Chapter 12 Part 1 Summative Review

How do you calculate the mean?

• Put the data in order and find the middle number. If there are two numbers in the middle add them and divide by 2.

• Subtract the lowest number from the highest number.

• Subtract the first quartile from the third quartile.

• Find the sum of the data and divide by the number of data items.

How do you calculate the range?

• Put the data in order and find the middle number. If there are two numbers in the middle add them and divide by 2.

• Subtract the lowest number from the highest number.

• Subtract the first quartile from the third quartile.

• Find the sum of the data and divide by the number of data items.

When finding the median, you add up all the numbers in the data set and divide by how many numbers are in the data set.

• True

• False

How do you calculate the interquartile range?

• Put the data in order and find the middle number. If there are two numbers in the middle add them and divide by 2.

• Subtract the lowest number from the highest number.

• Subtract the first quartile from the third quartile.

• Find the sum of the data and divide by the number of data items.
