Assume that the mean of a dataset is 100 and the standard deviation is 5. If we multiply each value in the data by 2, what would be the new standard deviation?

Sagot :

Answer:

7

Step-by-step explanation:

Using statistical concepts, it is found that the new standard deviation of the variable would be of 10.

When a constant is multiplied to each data in a variable:  

  • The mean is multiplied by this constant.
  • The standard deviation is multiplied by this constant.

In this problem, the standard deviation of the variable is 5, multiplied by 2, hence:

5 x 2 = 10

The new standard deviation of the variable would be of 10.
