What is a histogram?

Back

A histogram is a type of bar graph that represents the frequency distribution of numerical data. It shows how many data points fall within specified ranges (bins).

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 continuous data and shows the frequency of data points within certain intervals.

How do you determine the number of students in a specific height range using a histogram?

Back

To find the number of students in a specific height range, locate the corresponding bar in the histogram and read the height of the bar, which represents the frequency of students in that range.

Front

What does the x-axis represent in a histogram?

Back

The x-axis in a histogram represents the intervals (bins) of the data being measured.

Front

What does the y-axis represent in a histogram?

Back

The y-axis in a histogram represents the frequency or count of data points that fall within each interval.

Front

How do you find the interval with the greatest frequency in a histogram?

Back

To find the interval with the greatest frequency, compare the heights of the bars in the histogram and identify the tallest bar.

Front

What is the purpose of using intervals (bins) in a histogram?

Back

Intervals (bins) are used in a histogram to group data points into ranges, making it easier to visualize and analyze the distribution of the data.

Front

How can you interpret the shape of a histogram?

Back

The shape of a histogram can indicate the distribution of the data, such as whether it is normal, skewed, or has multiple peaks.

Front

What is the significance of the area under the bars in a histogram?

Back

The area under the bars in a histogram represents the total number of data points in the dataset.

Front

How do you calculate the frequency of a specific interval in a histogram?

Back

The frequency of a specific interval is calculated by counting the number of data points that fall within that interval.
