Circle Graphs/Histograms

A circle graph, also known as a pie chart, is a circular statistical graphic divided into slices to illustrate numerical proportions.

A histogram is a type of bar graph that represents the frequency distribution of numerical data, showing how many data points fall within specified ranges.

To interpret a circle graph, look at the size of each slice to understand the proportion of each category relative to the whole.

A histogram displays data in continuous intervals, while a bar graph represents discrete categories.

The height of a bar in a histogram represents the frequency or count of data points within that interval.

To find the total number of data points, sum the heights of all the bars in the histogram.

The purpose of using a circle graph is to show the relative sizes of parts to a whole, making it easy to compare proportions.

A frequency distribution is a summary of how often each value occurs in a dataset.

The mode can be determined from a histogram by identifying the interval with the highest bar.

The range of data in a histogram is the difference between the highest and lowest values in the dataset.
