Which set of population data is the least dispersed from its mean?

a) 2, 3, 2, 9
b) 4, 0, 4, 0
c) 6, 2, 2, 2
d) 9, 3, 5, 3

The set of population data in option C is the least dispersed from its mean.

Step-by-step explanation:

The observations of first option are 2,3,2,9.

The observations of second option are 4, 0, 4, 0.

The observations of third option are  6, 2, 2, 2.

The observations of fourth option are 9, 3, 5, 3.

Since the variance of third option is minimum, therefore the set of population data in option C is the least dispersed from its mean.

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
