# If A Particular Sample Has 36 Participants And The Other Sample Has 40 Participants, What Is The Total Degrees Of Freedom For The Study?

Degree of freedom is the number of independent values in a sample minus the number of population parameters estimated from that population.

v = n - k

v= degree of freedom

n= number of individual present in a sample

k= number of parameters which are estimated

In the given question, two samples are given. The first sample has 36 participants and second sample has 40 participants. The total degrees of freedom can be calculated as;

v = n1 + n2 - k

n1 = 36, n2= 40 and k=2

v = 36 + 40 - 2

v = 74
thanked the writer.
First sample size=n1=36

Second sample size=n2=40

For pooled variance degree of freedom is;

v=n1+n2-2

v=36+40-2

v=74

Degrees of freedom is the number of independent values in a sample minus the number of population parameters estimated from the sample.

For two populations the degrees of freedom is calculated as;

Degree of freedom = n1 + n2 - k

sample size of first sample = n1 = 36

Sample size of second sample = n2 = 40

k = 2

degrees of freedom = 36 + 40 - 2

Degrees of freedom = 74
