What is an interval in a histogram?

How do you determine the frequency of an interval in a histogram?

Back

The frequency of an interval is determined by counting how many data points fall within that range.

Front

What does the height of a bar in a histogram represent?

Back

The height of a bar in a histogram represents the frequency of data points within the corresponding interval.

Front

How can you tell which interval has the most data points in a histogram?

Back

You can tell which interval has the most data points by identifying the tallest bar in the histogram.

Front

What type of data is best represented by a histogram?

Back

Histograms are best for continuous numerical data, where data points can fall within a range.

Front

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

Back

A histogram displays the distribution of numerical data using intervals, while a bar graph compares categorical data.

Front

How do you create a histogram?

Back

To create a histogram, divide the data into intervals, count the frequency of data points in each interval, and then draw bars for each interval with heights corresponding to their frequencies.

Front

What is the x-axis in a histogram?

Back

The x-axis in a histogram represents the intervals or ranges of data.
