7. ABOUT Y AXIS AND X AXIS
• Having the dependent variable on the Y-axis
and the independent variable on the X-axis
allows the viewer to see the results at each
level of the dependent variable on one
graph rather than having to consult multiple
figures.
8. ABOUT BAR GRAPHS
• A bar graph is a chart that use either horizontal or
vertical bars to show comparisons among categories.
• One axis of the chart shows the specific categories
being compared, and the other axis represents a
discrete value.
• Some bar graphs present bars clustered in groups of
more than one

10. About circle graphs
• A circle is the same as 360°.
• A part of a circle is called an arc and an
arc is named according to its angle.
• You can divide a circle into smaller
portions.
• A circle graph, or a pie chart, is used to
visualize information and data.
