If the variance of some data is 37.33, what is the standard deviation? 6.11 228.08

In statistics, the value for the standard deviation of the given set of data points is rather calculated very simply. The value is calculated by taking the square root of the variance.
If we let s be the standard deviation and the variance be v, the concept above can be expressed into,
                 s = sqrt (v)
If we substitute the given value for v from the problem written above, the answer would be,
                s = sqrt (37.33) = 6.11

Hence, the answer is the first choice. 

Median : 66 .

Step-by-step explanation:

Given : 66, 51, 77, 68, 60, 75, 54, 80 29 64 66 67.

To find : What is the median of this set of data.

Solution : We have given the data set 66, 51, 77, 68, 60, 75, 54, 80 29 64 66 67.

Arranging in increasing  order :  29, 51, 54, 60 , 64 ,66, 66, 67, 68, 75, 77,80.

There are 12 numbers of set

Median = average of two middle terms

Median :   term.

Median  :  66.

Therefore, Median : 66 .
