How to Find Mean, Median, and Mode of a Data Set

The video tutorial explains how to solve a standardized math test question using mean, median, and mode. It covers four parts: calculating the median, understanding the mode, finding the mean, and determining the time spent drawing on day 7. Each part includes a pause for students to solve the problem before the solution is explained.

What is the median of the following data set: 8, 15, 16, 20, 40, 45?

• 16

• 18

• 22

• 20

If a data set has no repeating numbers, what can be said about its mode?

• It has two modes

• It has no mode

• It has one mode

• It has three modes

How do you calculate the mean of a data set?

• Subtract the smallest number from the largest

• Identify the most frequent number

• Find the middle number

• Add all numbers and divide by the number of items

What is the mean of the data set: 8, 15, 16, 20, 40, 45?

• 28

• 26

• 24

• 22

If the mean of 7 days is 30 minutes, and the total for the first 6 days is 144 minutes, how many minutes were spent on the 7th day?

• 60

• 66

What is the total sum of minutes for 7 days if the mean is 30 minutes?

• 270
