Read the following scenario, select the best test, calculate the answer, and interpret the results.

Many research studies have focused on pre-school for all children.Since many districts face budget cuts, funding pre-school programs may impact other offerings. Before making recommendations, administrators in a large district took a random sample of 50 seventh graders and compared the pre-algebra achievement levels of those who attended pre-school to those who did not. Based on these results, is there an association between attending pre-school and pre-algebra achievement?

A Spearman's r_swould be the best choice.Theresults indicate no relationship between the variables,(r_s[50] = -1.00,p> .05).There is no relationship between performance and pre-school attendance.

A chi-square test would be the best choice because you have frequency (observed) data.The results indicate that there is no relationship between the variables, (X²[1, N =50] = 1.34,p> .05).Whether or not a student attended pre-school did not impact performance in pre-Algebra.
