1. Graphing In Science

2. Bar Graphs The bars have to be spaced out The data is non-continuous
Type of Candy
Vote
Coffee Crisp 4
Smarties 1
Sour Patch Kids 8
Swedish Berries
Kit-Kat 6
Caramilk
The bars have to be spaced out
The data is non-continuous
Is typically used to describe voting data

4. Histograms Height range # of individuals 5’-5’3” 4 5’4”-5’6” 9
5’7”-5’9”
5’10”-6’
6’1”-6’3” 2
The data in a histogram is continuous
This means that there are NO gaps between the bars
The data for each bar is a range

6. Line graphs Tend to be continuous
Time (seconds)
Distance (meters) 1 4 2 8 3 12 16 5 20 6 24 7 28
Tend to be continuous
A line is often used to connect the points
The points can also be discontinuous which produces a non-linear graph

8. Shapes of Graphs Direct relationship (a straight line with an angle)
A = kB
Exponential relationship (a curved line)
A = kB2
No relationship (A has no effect on B)
Inverse relationship or inverse square relationship
A = k/B OR A = k/B2
