well when answering the mean you take the average of all the numbers so it be approxiamently around the answers and each number can affect the mean in many ways while a median is when you put the numbers in order and you get the middle number, because it is a middle the number can be far away from the beginning number or ending number. Mode is when the numbers appear the most and when picking mode it can be a dramatic change from the numbers around it. That is why calculating the mean average is better than take the median and mode, but sometimes some problems work better dealing with mode or median.

Why calculate for the mean and median in relation to a sample?
Both the mean and median represent the center of a distribution. Calculating the mean is easier, but may be more affected by outliers or extreme values. The median is more robust.
How does the mean and the median compare?
mean is the average of a bunch of numbers. the median is the middle number of the bunch. if the bunch has an even amount of numbers, you average the middle 2 numbers to get the median.
What does an IQ of 116 mean?
You're in the top of the average group. so not exceptional, but better than most. the median IQ is about 100, which is perfectly average.
How does the mean compare to the median?
The mean and the median are both involved with a set of numbers. The mean refers to the average of the numbers. The median refers to the middle number of the numbers
Do extreme values affect the median?
No they do not (or at least they have less of a significant impact) and this is the benefit of using the median average over the mean average.
