Interpreting Histograms: Key Concepts and Techniques

The video tutorial covers interpreting histograms with a focus on camera prices. It explains how to read a histogram, calculate the total number of cameras, identify cameras costing $200 or more, and determine the most common camera cost. The tutorial also evaluates statements to determine which must be true based on the histogram data.

What does the x-axis of the histogram represent?

• Camera models

• Camera brands

• Number of cameras sold

• Price ranges of cameras

How is the frequency on the histogram determined?

• By the color of the bars

• By the width of the bars

• By the height of the bars

• By the label on the x-axis

What is the total number of cameras represented in the histogram?

• 22 cameras

• 15 cameras

• 25 cameras

• 32 cameras

How many cameras cost between $0 and $99?

• 11 cameras

• 7 cameras

• 2 cameras

• 8 cameras

How many cameras cost $200 or more according to the histogram?

In which price range do most cameras fall?

• $400 - $499

• $0 - $99

• $100 - $199

Is it true that there is more than one camera that costs exactly $100?

• No, all cameras cost more than $100

• Yes, definitely

• No, it's not certain

• Yes, but only in one category

What can be said about the most expensive camera's price?

• Exactly $499

• Less than $499

• More than $200

• Cannot be determined

Do one fourth of the cameras cost between $200 and $299?

• Cannot be determined

• Only in certain conditions

• No

• Yes

Do over half of the cameras cost less than $150?

• Cannot be determined

• It's exactly half

• Yes

• No
