Exam 8: Analysis of Variance

The question below refers to the following situation: A social researcher is interested in studying the relationship between religious affiliation and years of education. Here is the data she is working with: What are your conclusions about the null hypothesis?

The question below refers to the following situation: A social researcher is interested in studying the relationship between religious affiliation and years of education. Here is the data she is working with: Calculate the mean square between groups (MSbetween).

The question below refers to the following situation: A social researcher is interested in studying the relationship between religious affiliation and years of education. Here is the data she is working with: Calculate the within-group sum of squares.

In ANOVA, the dependent variable is measured at the interval level.

The question below refers to the following situation: A social researcher is interested in studying the relationship between religious affiliation and years of education. Here is the data she is working with: Calculate the F ratio.

Groups in an analysis of variance are typically formed based on a __________ measure.

The sum of squares is the method for measuring variation:

The question below refers to the following situation: In an analysis of variance with 4 groups, each containing 12 respondents: Calculate the total degrees of freedom.

The __________ sum of squares is defined as

The question below refers to the following situation: A valet parking attendant is interested in whether daytime temperature affects the size of tips. To study this question, she records the size of the tip given by her customers on 3 extremely hot summer days, 3 warm spring days, and 3 cold winter days. Complete an analysis of variance to test the differences between mean tips with significance (α = .05), to determine if the groups differ from each other. Calculate mean square between.

The normality assumption required for using an F ratio holds if

The question below refers to the following situation: A social researcher is interested in studying the relationship between religious affiliation and years of education. Here is the data she is working with: Are your results statistically significant, and if so, at what level?

The mean square is:

Analysis of variance yields a(n) __________ whose numerator represents variation between groups being compared, and whose denominator contains an estimate of variation within those groups.

In Analysis of Variance, the dependent variable is measured at the nominal level.

The question below refers to the following situation: A researcher is interested in the effects of family size on leisure time. He questions 16 families on the number of "free hours per week." He polls 4 families at each size, from 1 to 4 children. The data are as follows: Calculate the mean square between groups.

The __________ sum of squares is defined as

The question below refers to the following situation: A researcher is interested in the effects of family size on leisure time. He questions 16 families on the number of "free hours per week." He polls 4 families at each size, from 1 to 4 children. The data are as follows: Calculate the total sum of squares.

In an analysis of variance with three groups, the null hypothesis states:

The distance or deviation of raw scores from their group mean is known as:
