A simple analysis of variance is used to study participants who are tested:
Only once
The ANOVA is like an extension of the:
t-test
If you wanted to examine whether the degree of parental involvement differs based on students' grade in school (i.e. 1st, 2nd, 3rd, etc.), what is the independent variable of interest?
grade level
A researcher wants to create an intervention to improve the well being of first-semester graduate students, so she gives one group of students specific doses of rocky road ice cream, the next group of students specific doses of licorice, and the third gro
analysis of variance
If you wanted to examine whether the degree of parental involvement differs based on students' grade in school (i.e., 1st, 2nd, 3rd, etc.), what is the dependent variable of interest?
degree of parent involvement
When interpreting F (2, 27) = 8.80, p < .05, how many groups were examined?
3
What is the first step in the computation of the F statistic?
Stating the null and research hypotheses
If your MS within is higher than your MS between, your F value will be:
lower
If you perform multiple t-tests, which of the following is true?
Type I error increases
When computing the degrees of freedom for ANOVA, how is the between group estimate calculated?
k-1
The ANOVA can be used to test the differences between:
two or more group
Using ANOVA, a null hypothesis could look like:
H0 = �1 = �2 = �3
In order to increase the value of the F statistic, which of the following must occur?
MSwithin < MSbetween
When computing the degrees of freedom for ANOVA, how is the within group estimate calculated?
N - k
ANOVA first tests for an overall difference between the means. This is known as what type of test?
omnibus
If your MS between is higher than your MS within, your F value will be:
higher
In order to look at specific comparisons between groups, you need to conduct:
Post hoc comparisons
The variability within groups is due to ______________.
chance
If the amount of variability due to within group differences is equal to the amount of variability due to between group differences, your F value will be equal to:
1
A simple analysis of variance includes this many factors or treatment variables in the analysis:
only one
The variability between groups is due to ______________.
thr grouping factor
If your MS within is lower than your MS between, your F value will be:
H1 = 2 ? 3
A simple analysis of variance is also called:
The one-way analysis of variance
Computing the between-group variance first calls for summing the difference between grand mean (means of all scores) and the group means. This is known as the _______.
SS between
