Exploring Measures of Center: Mean, Median, Mode, and Range

The video tutorial explains how to find the measures of center: mean, median, mode, and range. It begins with an introduction to these concepts, followed by detailed steps to calculate each one. The mean is calculated by adding all numbers and dividing by the count. The median is found by ordering numbers and identifying the middle value. The mode is the most frequently occurring number, and the range is the difference between the maximum and minimum values. The tutorial provides clear instructions and examples for each measure.

What is the mean of the numbers 1, 1, 2, 3, 4, 5?

• 3

• 21

• 2.67

• 16

How do you calculate the mean of a dataset?

• Find the most frequent number

• Add all numbers and multiply by the count

• Add all numbers and divide by the count

• Subtract smallest from largest

If a dataset is ordered from smallest to largest, what position would the median be in for 6 numbers?

• 3rd

• 6th

• Between 3rd and 4th

• 4th

What is the median of the numbers 16 and 26?

• 20

• 22

• 42

• 21

What method is used to find the median in a dataset with an even number of elements?

• Average the two middle numbers

• Choose the larger middle number

• Choose the smaller middle number

• Sum all numbers and divide by two

What is the mode of the dataset where the numbers are 32, 5, 16, 26, 32?

• 32

• 26

• 16

• 5

How is the range of a dataset calculated?

• None of the above

• Divide the largest number by the smallest

• Add the smallest and largest numbers

• Subtract the smallest number from the largest

What is the range of the numbers 5 to 32?

• 32

• 27

• 37

• 25

Which of the following is a measure of center?

• Median

• Sum

• Difference

• Product

If the mode of a dataset is 32, what does it imply about the number 32?

• It is the smallest number

• It is the median

• It appears most frequently

• It is the largest number
