Answer #1

Variability refers to how spread out a group of data is. In other words, variability measures how much your scores differ from each other. Variability is also referred to as dispersion or spread. Data sets with similar values are said to have little variability, while data sets that have values that are spread out have high variability.

Therefore,

correct answers are

i)how much spread there is in a set of scores.

ii)how much scores cluster together.

iii)how much scores stretch out.
