Bar graph,Dot plot, and Circle graphs

A bar graph is a visual representation of data using bars of different heights or lengths to compare quantities across categories.

A dot plot is a simple way to display data using dots above a number line, where each dot represents one data point.

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

You add the heights of the bars representing each category to find the total number of students.

Subtract the height of the bar for one category from the height of the bar for the other category.

Each dot in a dot plot represents one individual data point or observation.

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

Graphs help to visualize data, making it easier to compare, analyze, and interpret information.

Bar graphs are best for comparing categorical data.

Dot plots are best for displaying small sets of quantitative data.
