Understanding Range, Mean, Median, and Mode

The video tutorial explains how to calculate the range of a set of numbers by finding the difference between the greatest and least numbers. It provides examples to illustrate the concept. Additionally, it covers how to find the mean, median, mode, and range using a chart, with step-by-step instructions and examples.

What is the range of a set of numbers?

• The most frequently occurring number in the set

• The sum of all numbers in the set

• The average of all numbers in the set

• The difference between the least and greatest numbers

In the set {0, 15, 8, 23}, what is the range?

• 0

• 8

• 23

• 15

What is the purpose of using a chart in data analysis?

• To eliminate the need for calculations

• To make data look more colorful

• To increase the number of data points

• To organize and visualize numbers better

How do you calculate the mean from a set of numbers?

• Add all numbers and divide by the number of items

• Subtract the smallest number from the largest

• Find the middle number in the set

• Identify the most frequent number

What is the median of the set {1, 2, 2, 3}?

• 2.5

• 2

• 1

• 3

Which number is the mode in the set {1, 3, 2, 2}?

• None

• 2

• 3

• 1

How do you find the range from a chart?

• Find the middle number in the set

• Add all numbers and divide by the number of items

• Subtract the smallest number from the largest

• Identify the most frequent number

If a chart shows the number of siblings as {1, 3, 2, 2}, what is the range?

• 4

• 1

• 2

• 3

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

• Add all numbers together

• Order the numbers from least to greatest

• Identify the most frequent number

• Subtract the smallest number from the largest
