Answer to Question #226068 in Statistics and Probability for Carrie

Question

Consider the following partial analysis of variance AN OV A table.

Source of variation d f SS M S F

Treatments    75 25   

Error    60   

TOTAL 19 135

The test statistic is

1. 28:75

2. 6:67

3. 0:15

4. 100

5. 6:067

Answer 1

Df treatments = SS_treatments/MS_treatments = 75/25 = 3

Df error = DF_total- Df_treatments = 19 - 3 = 16

MSerror= SS_error/Df_error = 60/16 = 3.75

Test statistic F = MS_Treatments /MS_Error = 25/3.75 = 6.67

Answer = 6.67
