|
THE ASSUMPTIONS OF POWER
|
AS SAMPLE SIZE INCREASES POWER INCREASES
THE SMALLER ALPHA IS THE LOWER THE POWER AS POWER INCREASES GAMMA INCREASES |
|
|
WHAT IS GAMMA
|
THE DEGREE TO WHICH THE NULL HYPOTHESIS IS FALSE
hOW LARGE OF AN EFFECT THE IV HAD ON THE POPULATION |

SAMPLE SIZE IS RELATIVELY THE SAME CONTROL GROUP AND EXPERIMENTAL GROUP HOMOGENEITY OF VARIANCE SCORES |
|
|
HOMOGENEITY OF VARIANCE
|
THE LARGEST VARIANCE CANT BE MORE THAN DOUBLE THE SMALLEST VARIANCE, NEEDS TO BE PRESENT IN ORDER TO CONDUCT A T-TEST
|
|
|

|
SHOWS THE EFFECT OF THE IV WHEN THE STD DEV IS NOT KNOWN, USED WITH MATCHED GROUPS OR REPEATED MEASURES DESIGN
|

|
BETWEEN GROUP VARIANCE
|
IN THE ANALYSIS OF VARIANCE IT IS THE DIFFERENCES IN MEANS BETWEEN THE DIFFERENT GROUPS BEING STUDIED
|
|
