You conduct an experiment and calculate for variable A (A goes from 0 to 100 and is approximately normally distributed) the mean, median, standard deviation, range and interquartile range. Afterwards you see that the two most extreme values of A wer not entered correctly. You change the minimum value from 0 to 5 and you change the maximum value from 100 to 90. After this change, these values are still the most extreme values.

How does the standard deviation change?
