. One sample has M = 18 and a second sample has M = 14. If the pooled variance for the two samples is 16, what is the value of C

dalvyx [7]

Answer:

Cohen's d : 1.00

Step-by-step explanation:

We know that M₁ = 18, and M₂ = 14. Given that the pooled variance for the these two samples are 16, S²Pooled = 16, and therefore S - pooled = 4.

The formula to solve for the value of Cohen's d is as follows,

d = M₁ - M₂ / S - pooled,

d = 18 - 14 / 4 = 4 / 4 = 1

Therefore the value of Cohen's d = 1

3 x (7+2) all you have to do is add 7+2 and that is 9 and then you have to multiply 3 x 9
