17
Q

Most crude, simplest measure of variability

A

Range

18
Q

How to get the range?

A

HS-LS=range

19
Q

Scores are spread, scattered and far from each other

A

High Standard Deviation

20
Q

Heterogeneous

A

Standard deviation (no singularity)

21
Q

Scores are clustered, near, and homogeneous

A

Low standard deviation

22
Q

Which performs better: High or Low standard deviation ?

A

Low standard deviation (because the scores of the students are near to each other)

23
Q

Stanine
Quartile

24
Q
