A histogram is a type of bar graph that represents the frequency distribution of a set of data. It is used to show the distribution of numerical data and helps to visualize the shape, center, and spread of the data.
1. Bars: The bars on a histogram represent the different intervals or ranges of the data. The height of each bar corresponds to the frequency or count of data points within that interval.
2. X-axis: The x-axis of a histogram represents the intervals or categories of the data. It is a number line that shows the range of values being analyzed.
3. Y-axis: The y-axis of a histogram represents the frequency or count of data points within each interval. It measures how often a particular value or range of values occurs in the data set.
To create a histogram, follow these steps:
When interpreting a histogram, consider the following:
Here are some key points to remember about histograms:
Remember to practice creating and interpreting histograms with different sets of data to strengthen your understanding of this important visual representation of data.
