3. From what I can make out, the only change is the 16 in the first set to 106 in the second set. The way this will change the mean, median, and mode is as follows:
The mode is the one that occurs most often and it doesn't change in this case. Which number is seen the most times in each set?
The median is the number that is in the middle when you put the numbers in order from least to greatest. In this case you have to add the middle two then divide by two since there are 10 numbers in the set. This is different for each of the above.
The mean, or average, will change because you get it by adding all of the numbers the dividing by 10 (the amount of numbers in the set)
Do these things and you will be able to see the results. Good Luck!
