A research report from an independent-measures study states that there are significant differences between treatments, F(3, 48)
Flura [38]

Answer:

k = 4 ;

N = 52

Step-by-step explanation:

Given the ratio F(3, 48)

F takes in degree of freedom values; degree of freedom of groups ; degree of freedom of error

Hence,

df group or treatment = 3

df error = 48

df treatment = k - 1

k = Number of groups

3 = k - 1

3 + 1 = k - 1 + 1

4 = k

Number of treatment condition = 4

df error = N-k

N = total number of observations

48 = N - 4

48 + 4 = N - 4 + 4

52 = N
