Inverse variation: y=k/x

1. plug in the values: (15,1)
1=k/15

2. solve for k

3. Now, plug in what you can for the second point: (n,5)
5=k/n (if you do the step above, you will know “k”.

4. Solve for “n”

For an independent-measures research study (i.e., independent measures t Test), the data show an 8-point difference between the

zloy xaker [14]

Answer:

C. 2

Step-by-step explanation:

Cohen's d is a parameter used to express the standardised difference between two means. It is defined as the difference between the means divided by the pooled standard deviation.

In this case, the difference between both means (M2-M1) is 8. As for the pooled standard deviation, simply take the square root of the given pooled variance:

$S=\sqrt{S^2}\\S=\sqrt{16} \\S= 4$

Therefore, the value of Cohen's d (d) is:

$d=\frac{M_{2} -M_{1}}{S} \\d=\frac{8}{4}\\d=2$
