Question
We want to compare the average test scores for students exposed to one of three different teaching techniques (three levels of a single independent variable). Decide what statistical procedure would most likely be used to answer the research question. Assume all assumptions have been met for using the procedure.
Two independent samples Z or t test
Use a chi-squared test
One sample Z or t test
Construct confidence interval(s)
Use regression to test the effect of an independent variable on a dependent variable
ANOVA

Explanation / Answer
Here we need to compare more than two teaching techniques i.e. three different levels of teaching techniques and hence, we will use ANOVA in this case.
Option F is correct.
