The mode of a data set can be found by...
subtracting the minimum from the maximum
choosing the middle number
choosing the number that occurs most
finding the sum of the numbers and then dividing by the total amount of numbers in the data set

a way of describing how limited a set of data is
a way of describing how spread out a set of data is
The mean of a data set can be found by...
subtracting the minimum from the maximum
choosing the middle number
