Graphing 1-3

Objective Create and analyze graphs based on numerical data. CLE 3202.Math.1 Understand the mathematical principles behind the science of physics.

Graphs Used to show numerical information in a useful format.

Each Graph must include: Title Units for each axis Label for each axis Scale Data

Example: Graph Title Data Y Axis X Axis

Variables Independent variable = X axis Dependent variable = Y axis

Three Main Types Bar Graph Line Graph Circle (Pie) Graph

A. Types of Graphs Bar Graph Shows information collected by counting

Bar Graph Data Ex:

Bar graph: used to compare quantities in different categories

A. Types of Graphs Line Graph shows the relationship between 2 variables Dependent Variable Independent Variable

Line graph: used to show change over time

Line Graph Continuous Change

Circle (Pie) Graph Percentages

A. Types of Graphs Pie Graph Shows distribution of parts within a whole quantity

Used to show how a part relates to the whole Pie Graph: Used to show how a part relates to the whole Needed to show percentages effectively NCHS’s Biology Ice Cream Survey Vanilla 21.0% Chocolate 33.% Strawberry 12.0% Raspberry 4.0% Peach 7.0% Neopolitan 17.0% Other 6.0%
