a researcher is studying whether average gpa is dependent on whether the students are in a 2-year college, public university, or private university. the researcher should use a 1-way anova for this study. True or False and why?



Answer :

The researcher should use a 1-way ANOVA for this study - True

The term ANOVA stands for analysis of variance. In the given case a one-way ANOVA would be an appropriate statistical test to use. It is used to test for significant differences between the means of two or more groups. In this case, the researcher is interested in determining whether the average GPA of students at different types of institutions namely the two-year college, public university, or private university which is is significantly different from one another.

To conduct a one-way ANOVA, the researcher would ideally need to gather the entire data on the GPA of a sample of students from each type of institution and calculate the mean GPA for each group. The researcher would then use statistical software to conduct the test and determine whether there is a statistically significant difference between the means of the groups.
