Question

I need help with a median problem.

Answer 1

Hi there! Can you find the median? Once you do that we will move on to the next step :)

Answer 2

45?

Answer 3

Well that would be the case if there were an odd set of numbers, but since there is an even amount, you take the two numbers that are in the middle, add them together, then divide by two.

Answer 4

in this case the 2 numbers are 55 and 45.

Answer 5

50 :)

Answer 6

Yes! awesome, now they ask how it would effect the median if the eldest employee resigns, so find the greatest number in the set, take it out then find the median.

Answer 7

Once you've done that, you will have all the elements to get your answer.

Answer 8

The median decreases by 5.

Answer 9

You got it :)
