What is a histogram primarily used for?

• Showing relationships between different categories.

• Providing a visual representation of a data frequency distribution.

• Displaying data over time.

• Comparing discrete data points.

What is a key difference between a histogram and a vertical bar graph?

• Histograms use horizontal bars, while bar graphs use vertical bars.

• Histograms represent categorical data, while bar graphs represent numerical data.

• Histograms have no gaps between bars, unlike vertical bar graphs.

• Bar graphs show frequency, while histograms show percentages.

What does the Y-axis in a histogram typically represent?

• Class limits

• Sales figures

• Frequency or the amount of data points in each class

• Class boundaries

What is the largest frequency value in the frequency distribution?

We use class boundaries to avoid _____ between the bars when constructing the histogram

When data consists of whole numbers, how are class boundaries calculated to ensure no gaps between bars in a histogram?

• Subtract 0.5 from the lower class limits and add 0.5 to the upper class limits.

• Add 0.5 to the lower class limits and subtract 0.5 from the upper class limits.

• Round all class limits to the nearest whole number.

• Use the exact class limits as boundaries.

What does a "broken axis" symbol on a histogram's X-axis indicate?

• The data is incomplete.

• There are no values in that range.

• The values in that section are condensed.

• The axis is not drawn to scale.

The next value that you would write on the y axis is ____________

In the video's example, how many classes were used to construct the histogram?

• 4

• 5

• 5

• 7

• 8
