How many degrees of freedom are there for the between-group variance, the numerator of the F-statistic?
Assume you used Analysis of Variance to compare the student debt for 100 college graduates--25 from LSU, 25 from LCC, 25 from Stetson, and 25 from University of Phoenix.
How many degrees of freedom are there for the within-group variance, the denominator of the F-statistic?
Assume you used Analysis of Variance to compare the student debt for 100 college graduates--25 from LSU, 25 from LCC, 25 from Stetson, and 25 from University of Phoenix.
If the between-group variance equals 500 and the within group variance equals 50, what is the value of F
Homework Answers
Since total number of observation = 100
Number of factor = k = 4
So degree of freedom of numerator
= k-1 = 4-1 = 3
The degree of freedom of denominator
= n-k = 100-4 =96
Since MST = 500
MSE = 50
F = MST/MSE = 500/50 = 10

Analysis of variance compares the means of a response variable for several groups. ANOVA compares the variation within each group to the variation of the mean of each group. The ratio of these two is the F statistic from an F distribution with (number of groups - 1) as the numerator degrees of freedom and (number of observations - number of groups) as the denominator degrees of freedom. You intend to conduct an ANOVA with 4 groups in which each...

Problem 3. (Life cycle hypothesis) A student graduates from college at age 25 without any initial wealth or savings and starts working. The annual income of the student is S60,000. When the student retires later in life at the age of 65 she doesn't expect to get any retirement benefits and will rely on her savings. We assume that the person does not earn any interest on the savings and that her life expectancy is 85 years. Also, assume that...
