The numbers of students in the 7 schools in a district are given below.

(note that these are already ordered from least to greatest.)

179, 229, 235, 244, 252, 291, 348

suppose that the number 348 from this list changes to 236.

what happens to the mean? does it decrease by what? or does it increase by what? or does it stay the same?

what happens to the median? does it decrease by what? or does it increase by what? or does it stay the same?
