What is the mode of a data set?

• The middle number.

• The average.

• The number that occurs the most.

What is the median of a data set?

• The largest number minus the smallest.

• Adding up all of the numbers and dividing by how many there are.

• The middle number in a data set.

• The most common number in a data set.

• The meanest number in a data set.

What do you think the difference is between the mean and the median in a set of data? They both give us a "middle" or "average" number. Why would I use one over the other?
