GUESS THE GRAPH

100

This graph is a way of displaying categorical data using rectangular bars with heights or lengths proportional to the values they represent.

BAR CHART

200

This type of graph is used to represent the cumulative frequency or relative cumulative frequency of the data points

CUMULATIVE FREQUENCY GRAPH

300

This graph represents the distribution of a single variable and is useful for showing the frequency of individual values or ranges of values in a dataset.

HISTOGRAM

400

This type of graph is used to represent ordered pairs in the coordinate plane, often to determine the relationship between two variables.

CARTESIAN COORDINATE GRAPH

500

This graph type combines a line graph and a bar graph, with bars for individual values and a line to show the overall trend.
