A student is interested in the effect of environmental conditions on task performance. She makes participants complete a series of math problems under different conditions of temperature-cold, warm, and hot, and different noise conditions-quiet and noisy. The most appropriate test to analyze the data would be a(n) _____.

A) t-test
B) Pearson r
C) chi-square
D) F-test

The experiment involves multiple independent variables (temperature and noise conditions) and one dependent variable (task performance). Therefore, the most appropriate test to analyze the data would be a two-way ANOVA, also known as an F-test. This test will allow the researcher to examine the main effects of each independent variable as well as the interaction effect between them.
