if the highest score in a distribution is raised by 10 what will happen? to the mean an median
Homework Answers
If the highest score in the distribution is increased by 10 then the mean will increase as it depends on all the samples. On the other hand, median will not change because median represents the middlemost value and doesn't depend on extreme values.
