DSRT 734: Choosing a Test From the Blue Versus White Scatterplot — Item 23

DSRT 734 Question

Given the following scatterplot of the variables Blue versus White,
choose the most appropriate test to analyze the data.

Blue vs White Scatterplot

[SCATTERPLOT IMAGE]


Option A

Spearman's rho correlation


Option B

Pearson's chi-square


Option C

Pearson's correlation


Option D

Independent samples t-test

What this question assesses

This question assesses selection among rank correlation, count-table association, linear correlation, and independent-group comparison using an unavailable scatterplot whose option order must remain intact.

How to approach this type of question

The missing image means the source does not reveal the pattern required for selection. When the original scatterplot is supplied, verify that Blue and White are paired measurements and identify their scales. Examine whether the cloud is linear, merely monotonic, curved, clustered, tied, or influenced by outliers. Link those observations to each candidate’s data requirements rather than using the word “scatterplot” as an automatic test selector. A contingency-table method needs category counts, while a group-comparison method requires an outcome split by independent groups; correlation methods require paired measurements but differ in the forms and scales they summarize. Treat Item 23 independently from Items 14 and 15 because its original image may have differed and its options are ordered differently. No image is inferred and no option is selected.

Keep notes for Item 23 separate and retain the exact option sequence shown in this question. If the missing image becomes available, inspect its axes before analysis. Compare linear and monotonic form separately, and note ties or outliers that could change method selection. Also record the variable scales, point pattern, clusters, and any influential observations before evaluating the available methods. Until that evidence exists, do not borrow the visual interpretation or proposed option from either related item. Confirm that the image belongs to Item 23 before connecting any direction, form, or choice. Keep the original visual without redrawing points.
