In this paper we show that centering the data can considerably increase attribute estimation accuracy, where data values can be read off approximately by projecting embedded points onto calibrated (i.e., labeled) axes, similarly to classical statistical biplots. In addition, this idea can be coupled with a recently developed orthonormalization process on the axis vectors that prevents unnecessary distortions.

Concretely, we study: the difference between the estimates of k as given by participants when using different multidimensional projections; the accuracy of user estimations with respect to the number of labels in the data sets; the perceived usability of each multidimensional projection; whether user estimates disagree with k values given by a set of cluster quality measures; and whether there is a difference between experienced and novice users in terms of estimates and perceived usability. The results show that: dendrograms (from Ward's hierarchical clustering) are likely to lead to estimates of k that are different from those given with other multidimensional projections, while Star Coordinates and Radial Visualizations are likely to lead to similar estimates; t-Stochastic Neighbor Embedding is likely to lead to estimates which are closer to the number of labels in a data set; cluster quality measures are likely to produce estimates which are different from those given by users using Ward and t-Stochastic Neighbor Embedding; U-Matrices and reachability plots will likely have a low perceived usability; and there is no statistically significant difference between the answers of experienced and novice users. Moreover, as data dimensionality increases, cluster quality measures are likely to produce estimates which are different from those perceived by users using any of the assessed multidimensional projections.

This leads to a significant performance gain both in terms of accuracy and computational efficiency.

In this article we take a few steps in the direction of establishing such a foundation. Our approach is based on graphical perception-the visual decoding of information encoded on graphs-and it includes both theory and experimentation to test the theory. The theory deals with a small but important piece of the whole process of graphical perception. The first part is an identification of a set of elementary perceptual tasks that are carried out when people extract quantitative information from graphs. The second part is an ordering of the tasks on the basis of how accurately people perform them. Elements of the theory are tested by experimentation in which subjects record their judgments of the quantitative information on graphs. The experiments validate these elements but also suggest that the set of elementary tasks should be expanded. The theory provides a guideline for graph construction: Graphs should employ elementary tasks as high in the ordering as possible. This principle is applied to a variety of graphs, including bar charts, divided bar charts, pie charts, and statistical maps with shading. The conclusion is that radical surgery on these popular graphs is needed, and as replacements we offer alternative graphical forms-dot charts, dot charts with grouping, and framed-rectangle charts.}, + file = {/Users/cbbcbail/Zotero/storage/6WYNCPNR/Cleveland and McGill - 1984 - Graphical Perception Theory, Experimentation, and.pdf} +} + +@article{converseRoleProminentNumbers2018, + title = {The Role of ``{{Prominent Numbers}}'' in Open Numerical Judgment: {{Strained}} Decision Makers Choose from a Limited Set of Accessible Numbers}, + shorttitle = {The Role of ``{{Prominent Numbers}}'' in Open Numerical Judgment}, + author = {Converse, Benjamin A. and Dennis, Patrick J.}, + year = {2018}, + month = jul, + journal = {Organizational Behavior and Human Decision Processes}, + volume = {147}, + pages = {94--107}, + issn = {0749-5978}, + doi = {10.1016/j.obhdp.2018.05.007}, + urldate = {2024-02-14}, + abstract = {Numerate adults can represent an infinite array of integers. When a judgment requires them to ``pick a number,'' how do they select one to represent the abstract signal in mind?

A sample of 3\,billion stock trades reveals that traders' decisions reflect Prominent-Number clustering (Study 1) and a ``natural experiment'' reveals more clustering in rushed trading conditions (Study 2). Three sets of subsequent studies provide evidence consistent with an accessibility-based account of Prominent-Number usage: Experiments show that judges rely more on Prominent Numbers when they are induced to rush rather than take their time (Studies 3a and 3b), and when they are under high versus low cognitive load (Studies 4a, 4b, and 4c); and a final correlational study shows that Prominent-Number clustering is more apparent for judgments that require judges to scan a wider range of plausible values (Study 5).

Furthermore, we analyzed how this difference in response distribution was related to the wisdom of crowds (the aggregated judgment is as accurate as, or sometimes better than, the best individual judgment in the group) using computer simulations.

Our study suggests that cut-out charts which include collocated full context and focus are the best alternative, and that superimposed charts in which focus and context overlap on top of each other should be avoided.}, + keywords = {Data visualization,Dual-Scale Charts.,Focus+Context,Image color analysis,Quantitative Experiment,Quantization,Shape analysis,Terminology}, + file = {/Users/cbbcbail/Zotero/storage/S4YSSU4I/Isenberg et al. - 2011 - A Study on Dual-Scale Data Charts.pdf;/Users/cbbcbail/Zotero/storage/PJTUFHCV/6065014.html} +} + +@article{kaleVisualReasoningStrategies2021, + title = {Visual {{Reasoning Strategies}} for {{Effect Size Judgments}} and {{Decisions}}}, + author = {Kale, Alex and Kay, Matthew and Hullman, Jessica}, + year = {2021}, + month = feb, + journal = {IEEE Transactions on Visualization and Computer Graphics}, + volume = {27}, + number = {2}, + pages = {272--282}, + issn = {1941-0506}, + doi = {10.1109/TVCG.2020.3030335}, + urldate = {2024-03-05}, + abstract = {Uncertainty visualizations often emphasize point estimates to support magnitude estimates or decisions through visual comparison.

We find that adding means to uncertainty visualizations has small biasing effects on both magnitude estimation and decision-making, consistent with discounting uncertainty. We also see that visualization designs that support the least biased effect size estimation do not support the best decision-making, suggesting that a chart user's sense of effect size may not necessarily be identical when they use the same information for different tasks. In a qualitative analysis of users' strategy descriptions, we find that many users switch strategies and do not employ an optimal strategy when one exists.

Concretely, we study: the difference between the estimates of k as given by participants when using different multidimensional projections; the accuracy of user estimations with respect to the number of labels in the data sets; the perceived usability of each multidimensional projection; whether user estimates disagree with k values given by a set of cluster quality measures; and whether there is a difference between experienced and novice users in terms of estimates and perceived usability. The results show that: dendrograms (from Ward's hierarchical clustering) are likely to lead to estimates of k that are different from those given with other multidimensional projections, while Star Coordinates and Radial Visualizations are likely to lead to similar estimates; t-Stochastic Neighbor Embedding is likely to lead to estimates which are closer to the number of labels in a data set; cluster quality measures are likely to produce estimates which are different from those given by users using Ward and t-Stochastic Neighbor Embedding; U-Matrices and reachability plots will likely have a low perceived usability; and there is no statistically significant difference between the answers of experienced and novice users.

In particular, confirmation bias can cause people to overweigh information that confirms their beliefs, and dismiss information that disconfirms them. We tested whether confirmation bias exists when people reason with visualized data and whether certain visualization designs can elicit less biased reasoning strategies. We asked crowdworkers to solve reasoning problems that had the potential to evoke both poor reasoning strategies and confirmation bias. We created two scenarios, one in which we primed people with a belief before asking them to make a decision, and another in which people held pre-existing beliefs. The data was presented as either a table, a bar table, or a bar chart. To correctly solve the problem, participants should use a complex reasoning strategy to compare two ratios, each between two pairs of values. But participants could also be tempted to use simpler, superficial heuristics, shortcuts, or biased strategies to reason about the problem. Presenting the data in a table format helped participants reason with the correct ratio strategy while showing the data as a bar table or a bar chart led participants towards incorrect heuristics. Confirmation bias was not significantly present when beliefs were primed, but it was present when beliefs were pre-existing. Additionally, the table presentation format was more likely to afford the ratio reasoning strategy, and the use of ratio strategy was more likely to lead to the correct answer.

We observe two significant limitations in translating graphical perception knowledge into actionable visualization recommendation rules/constraints: inconsistent reporting of findings and a lack of shared data across studies. How can we translate the graphical perception literature into a knowledge base for visualization recommendation? We present a review of 59 papers that study user perception and performance across ten visual analysis tasks. Through this study, we contribute a JSON dataset that collates existing theoretical and experimental knowledge and summarizes key study outcomes in graphical perception. We illustrate how this dataset can inform automated encoding decisions with three representative visualization recommendation systems. Based on our findings, we highlight open challenges and opportunities for the community in collating graphical perception knowledge for a range of visualization recommendation scenarios.}, + isbn = {978-1-4503-9421-5}, + keywords = {Human Perception,Literature Review,Visualization Design}, + file = {/Users/cbbcbail/Zotero/storage/QXIFYYB5/Zeng and Battle - 2023 - A Review and Collation of Graphical Perception Kno.pdf} +} diff --git a/estimation.md b/estimation.md index 0393cf8..43cb742 100644 --- a/estimation.md +++ b/estimation.md @@ -7,7 +7,7 @@ csl: ieee.csl # Studies on Estimation in Visualization -* Two user studies conducting perception estimation tasks of visual variables on tiled, high-resolution wall-sized displays.

Students in a college course were given a sheet containing a series of pie charts and were asked to label the parts in each chart. The following week they did the same with a sheet of bar charts. Speed is measured by how many charts the student has completed after 5 minutes in the 13 minute experiment. The time spent on pie charts is very similar to bar charts with pie charts being slightly faster. Pie charts were found to outperform bar charts in terms of accuracy where they had smaller error and fewer large errors (greater than 3 points) than bar charts. The author concludes the pie chart is the superior choice for this task contrary to many cited works describing their inferiority without evidence. + +[@eellsRelativeMeritsCircles1926a] + +### Further Studies in the Graphic Use of Circles and Bars: A Discussion of the Eell's Experiment +#### von Huhn, 1927 + +* The authors note several limitations to the study done by Eells including that there is no condition including a scale for the bar chart and there are no tests of comparison tasks which they suppose bar charts will perform better at. They conduct a study comparing two bar charts with the equivalent pie charts. Each chart has two segments one set with a ratio of 1:1.5 and the other with ratio 1:4. The users are asked to report their answer in terms of the ratio of part A to part B. In terms of correctness, they find the bar chart outperforms the pie chart in both conditions and in terms of error in one condition. + +[@vonhuhnFurtherStudiesGraphic1927] + +### Bar Charts Versus Circle Diagrams +#### Croxton and Stryker, 1927 + +* The authors conducted studies comparing the estimation of parts using pie charts and bar charts in a similar manner to the Eells study but with a larger number of participants. The charts are presented with 2 to 5 segments individually on cards in a determined order and the subjects are asked to give the values for each segment. The authors attempt to characterize the chart with the higher accuracy for the different conditions and find that the pie chart outperforms the bar chart in all cases except for two cases with only two segments. + +[@croxtonBarChartsCircle1927] + +### Save the Pies for Dessert +#### Few, 2007 + +* The author of this blog post describes the flaws of the pie chart and argues that they should not be included in a visualization design program. They state that the primary strength of the pie chart is that the part-whole relationship is built into it in an obvious way and that the only advantage of the chart is that it is superior for understanding the combined proportion of parts in a dataset based on the studies by Spence and Lewandowsky. He claims that a bar chart with a quantitative scale is only slightly less effective than a pie chart for a 25% segment and that pie charts are only effective in judging values at 0, 25, 50, 75, and 100 percent but that these values can be better visualized by a bar graph. He also claims that alignment is a significant aid in reading values from a pie chart. He notes that adding labels and values to a pie chart is equivalent to producing a poorly designed table and that a bar chart is a better visualization than either a table or a pie chart. He also notes that augmentations such as 3D effects, internal divisions, transparency and gloss are harmful to reading the charts. Finally he states that comparisons between pie charts are difficult and this task is much better served by bar, line, and area charts. + +[@fewPiesDessert2007] + +### Judgment Error in Pie Chart Variations +#### Kosara, 2016 + +* The authors conducted a study comparing four variations of pie charts to a standard pie chart acting and a control. The variations were an expanded slice, an exploded pie, an elliptical pie and a square pie. They find that all variations cause an increase in error including those that do not distort the central angle. They find no change in response time and are unable to show a difference between models for angle, arc, or area compared with the results. This supports the idea that all three methods are used in estimating values from pie charts. + +[@kosaraJudgmentErrorPie2016] + +### Arcs, Angles, or Areas: Individual Data Encodings in Pie and Donut Charts +#### Skau and Kosara, 2016 + +* The authors conducted a study comparing baseline pie charts to a donut chart, an arc length chart, an angle chart, an angle donut chart and a circular area chart. The goal is to determine which encodings cause an increase in error over the baseline pie chart in order to determine which method is used for interpreting pie charts. The error for the angle only charts was greater than for the other charts. They conclude that angle encodings work well for some people but arc length and area work well for all. They also note possible issues with the angle only encoding of the chart that could call into question this conclusion. They asked participants what they thought they were using to read the charts and show that people who said they used angle performed better on the angle charts than those reporting another method. They note that encodings seem to combine in an additive manner with none of the individual encodings matching all of them combined. Finally they compare 6 donut charts with inner hole of size 0% to 97% of the radius. They show no impact from the donut chart variations except at 97%. + +[@skauArcsAnglesAreas2016] + +### Evidence for Area as the Primary Visual Cue in Pie Charts +#### Kosara, 2019 + +* The author conducted a study comparing various angles of 3D projections of pie charts at 90, 60, 30, and 15 degrees with 90 degrees being the equivalent 2D pie chart. They created models for users reading the charts by area, arc length, and angle based on the distortions introduced by each projection and fitted them to the results. The models fit showed area as the best fitting model followed by angle and then arc length. This indicates that area is the likeliest method for reading pie charts but does not rule out other possibilities such as back-projection into 2D and using another method. They are also able to show increased absolute error for the 30 and 15 degree conditions compared with the 2D chart. + +[@kosaraEvidenceAreaPrimary2019] + +### Evidence for Area as the Primary Visual Cue in Pie Charts +#### Redmond, 2019 + +* The author conducted a series of studies comparing the performance of pie charts and horizontal stacked bar charts with various visual cues for estimating viewer estimation of part-whole relationships.
