Measures of Center: Mean, Median, Mode

The video tutorial explains how to find the measures of center in a data set, focusing on the mean, median, and mode. It starts by calculating the mean by summing all data points and dividing by the number of points. Then, it demonstrates finding the median by ordering the data and identifying the middle value. Finally, it explains how to determine the mode as the most frequently occurring number in the data set.

What are the three types of measures of center discussed in the video?

• Mean, Median, Range

• Mean, Range, Mode

• Mean, Median, Mode

• Median, Mode, Range

How do you calculate the mean of a data set?

• Add all numbers and divide by the number of numbers

• Subtract the smallest number from the largest

• Find the middle number

• Identify the most frequent number

What is the mean of the data set if the total sum is 240 and there are 10 numbers?

• 26

• 22

• 24

• 28

What is the first step in finding the median of a data set?

• Add all numbers together

• Identify the most frequent number

• Arrange numbers from least to greatest

• Divide the total by the number of numbers

If the two middle numbers in a data set are 24 and 28, what is the median?

• 24

• 26

• 25

• 28

Which number is the mode in a data set where 28 appears more than once?

• 30

• 26

• 28

• 24

What is the mode of a data set?

• The middle number

• The average of all numbers

• The difference between the highest and lowest numbers

• The number that appears most frequently
