Exploring the Impacts of Aspect Ratios on Visual Perception in Scatterplots
… effect of aspect ratio on visual perception in scatterplots. Four tasks explored how the aspect ratio affects participants' perception of distance, amount, and correlation in scatterplots. The results showed that square aspect ratio scatterplots are more suitable for detecting length and number, …

Visualization and differential privacy
… graphs, pie charts, heatmaps, linear plots and scatterplots, present information from statistical database queries. Visualization products showed seasonal, daily and weekly periodic consumption patterns such that power utilities can make a qualitative analysis of consumption profiles. We call …

Study of intuitive eating ratings and self-efficacy differences in women with Polycystic Ovarian Syndrome (PCOS)
… intuitive eating scales was investigated using scatterplots, Pearson’s correlation coefficient, and a simple linear regression model. Ratings on the intuitive eating scale were dichotomized as high or low and self-efficacy ratings were compared.</p> <p><strong>Results</strong>: Of the 120 …

Canada Thistle Management Systems for Sustainable and Organic Farms
… from the bulk of the USDA sorghums in CDA and scatterplots. Multi-stemmed accessions may be useful for breeding improved summer annual cover crops that are tall, produce copious amounts of biomass, and rapidly regrow after defoliation; although propensity to lodging, poor germination, and …

Visual encoding quality and scalability in information visualization
… motion outlier detection in complex multivariate scatterplots. The results suggest a saliency deficit effect whereby global saliency undermines support to tasks that rely on local saliency. Finally, I investigate how discriminability, a classic visualization criterion, can explain recent empirical …

Measuring comprehension of abstract data visualisations
… a concrete applicable level, three-dimensional scatterplots are found to be efficient in trend detection but not in outlier detection. On a methodological level, ‘pop-out’ methodology is shown to be suitable for assessing visualisation efficiency. On a theoretical level, the cognitive account of …

VISUAL ANALYTICS FOR OPEN-ENDED TASKS IN TEXT MINING
… Gatherplots, which eliminate overplotting in scatterplots while maintaining individual objects. Another limitation in clustering methods is the fixed number of clusters as a hyperparameter. TopicLens is a Magic Lens-type interaction technique, where the documents under the lens are clustered …

Effect of Negotiator Active Listening Skills on Crisis (Hostage) Negotiations
… were identified via Pearson’s correlations, scatterplots were constructed for visual inspection of the data, which indicated potential support of hypotheses II and IV when considering the limitations of the study.

Plant Successional Patterns at Sperry Glacier Foreland, Glacier National Park, MT, USA
… by Kruskal-Wallis tests, Dunn's tests, and scatterplots. Species richness and vegetation cover were greater on older terrain. Plant composition changed over terrain age, with Penstemon ellipticus favoring older terrain and Boechera lemmonii favoring moderately aged terrain. Moderate drainage …

Sensitivity of MEPDG Using Advanced Statistical Analyses
… procedures such as tests for nonrandomness in scatterplots, linear and nonlinear regression analyses, and nonparametric procedures such as multivariate adaptive regression spline, gradient boosting machine are employed to identify and rank the significant input variables. Results show that …

Robustness redressed : an exploratory study on the relationships among overall assumption violation, model-data-fit, and invariance properties for item response theory models
… and canonical analyses were conducted. Scatterplots were used to study possible non-linear relationships. The means and standard deviations of "a" and "c" parameter estimates obtained by applying the three-parameter model to a data sample were used as indices of equal discrimination and …

Quantitative analysis of amphiphilic properties of membrane interactive proteins
… with the role of proteins in some cases. Scatterplots of mean hydrophobicity and mean hydrophobic moment for different window sizes revealed that there is a negative association between the two variates and, that mean hydrophobic moment decreases as window size increases. It was also …

Orbital Constellation Design and Analysis Using Spherical Trigonometry and Genetic Algorithms: A Mission Level Design Tool for Single Point Coverage on Any Planet
… constellations found based on optimal fitness. Scatterplots of the constellation design solution space and the multi-objective fitness function breakdown are provided to showcase convergence of the evolutionary genetic algorithm. The results highlight the ratio between constellation altitude and …
