Question

When computing the degrees of freedom for ANOVA, how is the between-group estimate calculated?

n/k

k – 1

n – 1

N – k

When interpreting F(2, 27) = 8.80, p < .05, what is the between-groups df?

27

3

30

2 The ANOVA is like an extension of the: t-test Correlation Regression F-test A simple analysis of variance includes this many factors or treatment variables in the analysis: Only one Three or more Only two One or more

Answer 1

Degrees of Freedom in ANOVA:

Number of Groups : k

Degrees of Freedom between Groups : Number of Groups - 1 = k-1

Ans : k-1

When interpreting F(2, 27) = 8.80, p < .05, what is the between-groups df?

2 = Denominator Degrees of feedom for F = Degrees of freedom between Groups.

Ans : 2

ANOVA is like an extension of t-test:

A hypothesis test that is used to compare the means of two populations is called t-test. A statistical technique that is used to compare the means of more than two populations is known as Analysis of Variance or ANOVA.

Therefore ANOVA is like an extension of t-test:

Ans : t-test

F-test

A simple analysis of variance includes this many factors or treatment variables in the analysis:

Ans : Three or more

A statistical technique that is used to compare the means of more than two populations i.e three or more is known as Analysis of Variance or ANOVA.
