Question

Assume a researcher wants to see if there are mean differences in body image between those who exercise in the front of an aerobic dance class vs. those who exercise at the back of the class. The researcher also wants to determine if the findings depend on whether the participants are male or female.

What is the DV?  What is the IV or IVs?

How many levels of each IV?

What are the three research questions that will be asked? Circle the one that is most important

What is the statistical analysis that will be used? Is this a one-way, two-way, or three-way ANOVA?

Assume that the researcher found that there was a significant (p < .05) interaction.

How would you graph this? (Indicate all axes and provide a legend; more than one way of drawing of this can be correct.)

Note: assumptions that must hold to use parametric statistics are:

Normality: Data have a normal distribution (or at least be symmetric)

Homogeneity of variances: Data from multiple groups have the same variance

Independence: Data are independent

Answer 1

What is the DV?

dependent variable (DV) : body image

What is the IV or IVs?

independent variable (IV): Exercise and Gender

How many levels of each IV?

there are two level of each IV

Exercise: 1.exercise in the front of an aerobic dance class and  2. those who exercise at the back of the class

Gender: 1.Male and 2. Female

What are the three research questions that will be asked? Circle the one that is most important

1.there is effect of exercise on body image,

2.there is effect of gender on body image and

3. there is interaction of gender and exercise

under line is most important

What is the statistical analysis that will be used? Is this a one-way, two-way, or three-way ANOVA?

two-way , since there are two independent variable
