Histograms

Front

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).

Front

What is the purpose of a histogram?

Back

The purpose of a histogram is to provide a visual representation of the distribution of data, making it easier to see patterns, trends, and outliers.

Front

How do you determine the range of a histogram?

Back

The range of a histogram is determined by subtracting the smallest value in the data set from the largest value.

Front

What are bins in a histogram?

Back

Bins are the intervals or ranges into which data is grouped in a histogram. Each bin represents a specific range of values.

Front

How do you find the frequency of a bin in a histogram?

Back

The frequency of a bin is found by counting the number of data points that fall within that bin's 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 bin.

Front

What is the least value in a data set?

Back

The least value in a data set is the smallest number in the set.

Front

How can you identify the mode from a histogram?

Back

The mode can be identified from a histogram as the bin with the highest bar (greatest frequency).

Front

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

Back

A histogram displays continuous data and groups it into bins, while a bar graph displays categorical data with separate bars for each category.

Front

How do you calculate the total number of data points from a histogram?

Back

To calculate the total number of data points, sum the frequencies of all the bins.
