The table gives the mean and standard deviation of four data distributions.



Mean Standard Deviation

Distribution 1 22 0.2

Distribution 2 21 0.8

Distribution 3 19 1.2

Distribution 4 20 3.2
which Distribution has the greatest spread.? help please !

Verified Answer :

The sample with the greatest standard deviation relative to the mean has the greatest spread.  Since the means are all similar, we just look at the distribution with the highest standard deviation.  This is Distribution 4, with a standard deviation of 3.2.

The distribution 4 has the greatest spread because the value of the  standard deviation is 3.2

What is the standard deviation?

It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.

As we know, the standard deviation will give idea about the spread of the data.

As we can see in the distribution 4

The standard deviation = 3.2

And 3.2 is the bigger than all other distribution.

Thus, the distribution 4 has the greatest spread because the value of the  standard deviation is 3.2
