Consider a dataset A with 55 observations, all distinct. Dataset D is created from A by adding 2023 to the largest observation in A and subtracting 2023 from the smallest observation in A. Which of the following is NOT true?

Given :- Consider a dataset A with 55 observations, all distinct. Dataset D is created from A by adding 2023 to the largest observation in A and subtracting 2023 from the smallest observation in A.

Concept used :- Adding and subtraction same value from data set does not change mean and standard deviation but median.

Solution :- Since observation in A and D are different then their middle values alter with the change in data set.

Hence Median of A is not equal to median of D
