Answer 1

## Fifteen people are randomly assigned, so that 5 people exercise in the morning, afternoon, or night. After 8 weeks, their weight loss is measured in pounds. Compute the degrees of freedom for Within treatments.

Answer : we have three treatment = 3

degree of freedom for treatment or ( Between group ) = 3 -1 = 2 and

n = total observation = 15

therefore degree of freedom for total = ( n -1 ) = 14

# degree of freedom for within group or error = degree of freedom for total - degree of freedom for between group

= 14 - 2  

= 12

## degree of freedom for within group is = 12
