Different List of values having the same mean and standard deviation may not contain the same values.

  • Mean gives the average value of the numbers in a list
  • Standard deviation measures the distance of the values from the average value of the distribution.
  • List of values with the same mean and standard deviation may not contain the same values.

For instance :

List A : [-1, -1, 0, 2]

Using a calculator ;

  • Mean = 0
  • Standard deviation = 1.1414

List B : [-2, 0, 1, 1]

Using a calculator ;

Mean = 0

Standard deviation = 1.1414

The mean and standard deviation of each list are the same, however, the values in each list are different.

Hence, Letitia is incorrect.
