Histogram and Frequency Table Concepts

This lesson teaches how to draw a histogram, a type of bar graph that displays data in equal intervals called bins. It uses an example of model airplane prices to explain frequency distribution. The video provides a step-by-step guide to creating a histogram, including scanning data, creating a frequency table, and drawing the graph. The lesson concludes with a summary and credits to Math Fun Academy.

What is the primary purpose of a histogram?

• To compare two different datasets

• To list data in a tabular form

• To show the frequency distribution of data

• To display data in a pie chart format

What are the intervals in a histogram commonly referred to as?

• Segments

• Bins

• Divisions

• Sections

In the example of the model airplane prices, how wide is each interval?

• $10

• $25

• $50

• $100

How many prices fall within the $25 to $50 interval in the model airplane example?

• 5

• 11

• 7

• 9

What is the first step in creating a histogram from data?

• Creating a pie chart

• Scanning the data for smallest and largest values

• Calculating the mean

• Drawing the axes

What is the range of the frequency table created in the lesson example?

• 150 to 450

• 200 to 500

• 100 to 400

• 50 to 300

Which interval does the number 209 fall into in the frequency table example?

• 250 to 300

• 200 to 250

• 150 to 200

• 100 to 150

What is the first number added to the frequency table in the example?

• 382

• 209

• 108

• 107

What is the interval width used in the frequency table example?

• 75 units

• 50 units

• 25 units

• 100 units

What is the largest data value in the example used for creating a histogram?

• 400

• 382

• 209

• 108
