by straight lines.

• Bar Graph

• Pie Chart

• Line Graph

• Ogive

It is a graph that uses parallel bars, either horizontal or vertical, to represent different counts/ frequencies for several categories.

• Bar Graph

• Pie Chart

• Line Graph

• Histogram

In constructing a pie chart, which of the following instrument should be used to divide the circle into its parts?

• Ruler

• Compass

• Meter stick

• Protractor

These are effective visual tools that help us present or display data or information in a most convenient way that readers could easily analyze without browsing the numbers.

• Frequency Distribution

• Data and files 

• Graphs and charts

• Survey questionnaire

The data set represents the scores on a mathematics quiz. What is the frequency for the interval 70-79?
