Create a data set of 15 numbers where the mean and median are both 59 and the standard deviation is between 10 and 11. Then, add
Ann [662]

What we should do is create a set of 15 data.

To comply with the mean and median 59, what we will do is make our center point 59, we will add 7 values ​​backwards and 7 values ​​forward, always the same value adding in the case forward or subtracting in the case of backwards the same number so that the mean is not affected

So:

We will add 2.5 in the same proportion, we start with the forward ones:

59 + 2.5 * 1 = 61.5

59 + 2.5 * 2 = 64

59 + 2.5 * 3 = 66.5

59 + 2.5 * 4 = 69

59 + 2.5 * 5 = 71.5

59 + 2.5 * 6 = 74

59 + 2.5 * 7 = 76.5

Backward:

59 - 2.5 * 7 = 41.5

59 - 2.5 * 6 = 44

59 - 2.5 * 5 = 46.5

59 - 2.5 * 4 = 49

59 - 2.5 * 3 = 51.5

59 - 2.5 * 2 = 254

59 - 2.5 * 1 = 56.5

Therefore, the entire data set would be:

41.5, 44, 46.5, 49, 51.5, 54, 56.5, 59, 61.5, 64, 66.5, 69, 71.5, 74, 76.5

We guarantee the mean and median 59.

The standard deviation is equal to 10.8

Now if we change the first value of 41.5 by 1000, we will see what happens:

New dataset:

1000, 44, 46.5, 49, 51.5, 54, 56.5, 59, 61.5, 64, 66.5, 69, 71.5, 74, 76.5

The mean changes to 122.9

And the standard deviation to 234.62

In other words, there is a significant increase in the mean, but in the standard deviation the growth is abysmal.

I attach an excel to check all this data.
