Circle Graphs/Histograms

Front

What is a circle graph?

Back

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

Front

What is a histogram?

Back

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.

How do you interpret a circle graph?

Back

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

Front

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

Back

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

Front

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

Back

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

Front

How do you find the total number of data points in a histogram?

Back

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

Front

What is the purpose of using a circle graph?

Back

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

Front

What is a frequency distribution?

Back

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

Front

How can you determine the mode from a histogram?

Back

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

Front

What is the range of data in a histogram?

Back

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