Question

A counseling psychologist wants to

determine if the color of light in the
room helps people to feel more
relaxed. Volunteers are each placed in
waiting room for 30 minutes, with the
lighting color being either white, red,
pink, green, purple, or blue. Afterwards
the relaxation level of each person is
assessed, and averages compared
between all the groups. Which
statistical test would be most
appropriate for this scenario?
correlation (one-tail, positive)
correlation (one-tail, negative)
correlation (two-tail)
ANOVA (F-test)
paired/dependent t-test (one-tail)
O paired/dependent t-test (two-tail)
independent t-test (one-tail)
independent t-test (two-tail)

Answer 1

For a counseling psychologist that wants to determine if the color of light in the room helps people to feel more relaxed. The most appropriate statistical test for this scenario is

• ANOVA (F-test)

What is the ANOVA (F-test)

ANOVA, which stands for Analysis of Variance, is a statistical method used to analyze the differences among group means in a sample. The ANOVA test is particularly useful when comparing means of more than two groups.

The F-test is a key component of ANOVA that helps determine whether the means of these groups are significantly different from each other.

The ANOVA (F-test) is the most appropriate statistical test when the counseling psychologist wishes to evaluate if the hue of light in the room influences people's relaxation levels.
