What is the mode?

• The middle number in an ordered set of data.

• The difference between the greatest and least amount in the data set

• The value that occurs the most often in a data set

• The sum of all the numbers in a data set divided by the size

Which is a synonym for "average?"

• median

• mode

• range

• mean

What do you do if there are two numbers in "the middle" when you are finding the median?

• Pick your favorite number

• They are both the median

• Find the mean of the two numbers

• None of the above

There can be more than one mean

• True

• False

There can be more than one mode

• True

• False

What is the first step when looking at a data set?

• Find the mean

• Sort the data into categories

• Find the range

• Put the data in ascending order

The mean of the data set can be found by...

• finding the sum of the numbers and then dividing by the total amount of numbers in the data set

• subtracting the minimum from the maximum

• choosing the middle number

• choosing the number that occurs most

What is the mode of the following data set...

4 , 8 , 5 , 17 , 5 , 4 , 9 , 5 , 6 , 82

• 4

• 9

• 6

• 5

If you score 76, 85, 97, and 83 on your math tests for the unit, what would your median score be?

• 84

• 90

• 85

• 88

Find the mean of these numbers:

5, 11, 2, 12, 4, 2

• 2

• 6
