How do you determine the total number of students represented in a histogram?

Back

To determine the total number of students, add the heights of all the bars in the histogram, which represent the frequency of each category.

Front

What does the x-axis represent in a histogram?

Back

The x-axis represents the intervals or bins of the data being measured.

Front

What does the y-axis represent in a histogram?

Back

The y-axis represents the frequency or count of data points within each bin.

How can you find the number of people in a group from a diagram?

Back

What is the purpose of a data display?

Back

The purpose of a data display is to visually represent data to make it easier to understand, analyze, and interpret.

Front

What is the difference between a bar graph and a histogram?

Back

A bar graph displays categorical data with rectangular bars, while a histogram displays numerical data and shows the frequency of data points in continuous intervals.

Front

How do you interpret the data from a histogram?

Back

To interpret a histogram, look at the height of the bars to understand the frequency of data points in each bin and identify trends or patterns.

Front

What does it mean if a histogram is skewed to the right?

Back

If a histogram is skewed to the right, it means that most of the data points are concentrated on the left side, with fewer high values stretching out to the right.

Front

How can you find the mode from a histogram?

Back

The mode is the bin with the highest bar in the histogram, indicating the most frequently occurring data range.
