One Common Use of Statistics in Education Is to Compile

Multiple Choice

One common use of statistics in education is to compile a composite score for each university on a list of universities. Suppose you thought that being a private university would contribute to having a higher ranking and that public universities would generally have lower ranks. To make sure that the age of the university didn't influence the comparison, you matched each private university with a public one that was founded at about the same time. Which statistic should you use to make this comparison between kinds of universities?

A) Mann-Whitney U test
B) Wilcoxon matched-pairs signed-ranks T test
C) Wilcoxon-Wilcox multiple comparisons test
D) Spearman r_s.
