TABLES AND GRAPHS NOTES
Vocabulary
 Tables are ways of organizing large amounts
of numbers in an easy to read format
 Graphs are a way of visualizing those
numbers in a clean way so that they are
easier to read
Is this a table or a graph?

Types of graphs
 There are three main types of graphs
 Bar graphs
 Line Graphs
 Circle Graphs
Bar Graphs
 Bar graphs are used to show relationships
between distinct different groups
 There is no possible way for there to be a
connection between them

Line Graphs
 Line graphs are used to show continuous
relationships
 There would be a measurement that could be
made in between two data points

WORKING WITH AVERAGES
How To Find an Average
 Add all of the numbers
together
 4
 7
 6
 8
 5
 4+7+6+8+5 =30
 Divide the sum by how
many numbers you
have
 5 numbers
 30/5 = 6
Why should we use averages
 Not all measurements are perfectly accurate
 If you repeat a process it will always be
slightly different
 To correct for errors that can occur in
experiments
