A sample of 88 students participated in a longitudinal study

A sample of 88 students participated in a longitudinal study of 386 students in northwestern Vermont to evaluate behaviors related to the students’ social functioning (whether or not they had social problems in the 9^th grade) and school performance (whether or not they dropped out of school during high school) to determine if there is an association between the variables and if so to what extent they are associated. What statistical technique should be used to analyze the data?

a.) one-way analysis of variance (ANOVA)

b.) chi square

c.) independent samples t-test

d.) pearson correlation.

Solution

Since both variables are binary, this can be tested using chi-square test of independence, it will also show how strongly they are associated.

b.) chi square
