Question

next, you play the song \bad guy\ while measuring billies brain activity from 5 different brain areas. which inferential statistic should you use to test if the 5 brain areas have different activity during the song? analysis of variance (anova) chi - square test correlation analysis t - test

Explanation:

• Analysis of variance (ANOVA) is used to test for differences among three or more group means. Here, we have 5 brain - areas (groups) and we want to test if their activity levels (means) are different.
• Chi - square test is used for testing the relationship between categorical variables, not for comparing means of multiple groups.
• Correlation analysis is used to measure the strength and direction of the linear relationship between two variables, not for comparing multiple group means.
• t - test is used for comparing means of two groups. Since we have 5 groups, a t - test is not appropriate.

Answer:

analysis of variance (ANOVA)
