Mean is the average of a given set of numbers. Find the median by adding all numbers in the set & dividing by the quantity of numbers in the set.
Median is the middle number of a given set of numbers. Put list in chronological order and take the center number. In a case of even numbers, average the two center numbers.
CURRENT MEAN (Average)
653 + 667 + 780 + 872 + 885 + 954=
4811
4811 ÷ 6 employees= 801.83
CURRENT MEAN (Middle #)
Since there are 6 numbers, find the average of the two middle numbers
653 667 780 872 885 954
780 + 872= 1652 ÷ 2= 826
NEW MEAN
695 + 667 + 780 + 872 + 885 + 954=
4853
4853 ÷ 6= 808.83
NEW MEDIAN
667 695 780 872 885 954
780 + 872= 1652 ÷ 2= 826
No change in median
ANSWER: The mean goes from 801.83 up to 808.83. The median remains the same at 826.
Hope this helps! :)
