Exam 14: Two Too Many Factors: Factorial Analysis of Variancea Brief Introduction

When the lines representing the effects of two variables are parallel on a graph,you have ______.

What is it called when the analysis of data reveals differential effects of one factor across levels of another factor?

A researcher wants to create an intervention to improve the well-being of graduate students in a counseling program,so she gives one group of students specific doses of rocky road ice cream,the second group of students specific doses of licorice,and the third group of students specific doses of chewy fruit-flavored candies for their treatments.As a second factor,she includes students in their first semester of their first year of graduate school as one cohort and students in the first semester of their second year of graduate school as the other cohort.The first factor in this intervention would be ______,the second factor would be ______,and the dependent variable would be ______.

In a weight loss study you find that participants differ in amount of weight lost based on their gender.What type of effect is this?

Interaction effects are between independent variables.

In the main effect F_(1,9) = 1.67,p = 0.229,what is 0.229?

In the main effect F_(1,12) = 5.25,p < 0.05,what is the number of 5.25?

How many times are subjects measured in the factorial ANOVA?

The number of main effects is equal to the number of ______.

If you wanted to examine whether attitudes toward learning differ based on students' grade in school (i.e. ,first,second,third),what is the independent variable of interest?

The test statistic used in the factorial ANOVA is the T-test.

In the main effect F_(1,9) = 1.67,p = 0.229,what does F stand for?

When results show a difference between levels of a factor,this difference is called ______.

One of the easiest ways to see the magnitude of an interaction (or the absence of one)in a factorial ANOVA is to plot the means.

A factorial ANOVA is a(an)______ analysis.

A researcher wants to create an intervention to improve the well-being of graduate students in a counseling program,so she gives one group of students specific doses of rocky road ice cream,the second group of students specific doses of licorice,and the third group of students specific doses of chewy fruit-flavored candies for their treatments.As a second factor,she includes students in their first semester of their first year of graduate school as one cohort and students in the first semester of their second year of graduate school as the other cohort.To analyze the differences in well-being between the students in the three different "treatments" and two cohorts,she would use a(n)______.

When your analysis finds that participants in a weight loss study differ in amount of weight lost based on the type of weight loss program used,what type of effect is this called?

Use a factorial ANOVA when you have ______ variables.

When the lines representing the effects of two variables cross on a graph,you have ______.

When analysis of data reveals a difference between levels of a factor,what is this called?
