Analyzing Bar Graph Frequencies

The video tutorial explains how to analyze a histogram with unequal class widths. It covers calculating the total frequency of each bar and determining the percentage of apples weighing between 150 to 200 grams. The process involves calculating frequencies for different weight ranges and using these to find the percentage of apples in the specified range.

What is the main objective of the video tutorial?

• To understand the history of apples

• To learn about different types of fruits

• To explore different types of histograms

• To calculate the percentage of apples within a specific weight range

What is the first step in calculating the percentage of apples?

• Counting the number of bars in the histogram

• Measuring the weight of each apple

• Calculating the total frequency of each bar

• Finding the total number of apples

How is the frequency of a bar determined?

• By the type of fruit it represents

• By the number of apples it contains

• By its width and height

• By its color

What is the width of the bar with a frequency of 8?

• 40

• 80

• 20

What is the height of the bar with a frequency of 5?

• 0.25

• 0.4

• 0.5

• 0.05

Which bar has the smallest frequency?

• The bar with a width of 40 and height of 0.05

• The bar with a width of 20 and height of 0.25

• The bar with a width of 20 and height of 0.4

• The bar with a width of 40 and height of 9.1

What is the height of the bar with a frequency of 10?

• 0.25

• 0.4
