1. Create a bar graph using the data below
Actions humans would take first in a
zombie apocalypse
Actions humans would take first in a
zombie apocalypse
Action
How many chose it as their first response
Seek refuge 22
Start hoarding
food 85
Make a video Diary 77
Be excited that “it’s really happening” 99
Quickly finish your bar graph because you know it’s due 49

2. Calculate the Y axis scale Calculate the Y axis scale
Highest number ________
Minus
Lowest number ________
= the “Range” ________
Divided the “Range”
by 50 = ________
Rounded this number
UP! To “nice number” _______

Look at your data table these numbers

****NICE NUMBERS*****
These numbers are what your round to
Use them to number your Y axis scale with:
Under
1.0 and above —2.0—5.0—10.0—20.0—25.0—50.0 etc…

3. Steps to Completing a Bar Graph: Steps to Completing a Bar Graph:
****REMBER NEATNESS COUNTS***********
The Set-up
Re-draw the “X” and “y” axis lines.
Title your graph
Full name and class period
Find and label the IV and DV
Label the IV= what is being “purposely changed” and is graphed in the “x” axis.
Label the DV= what is being “measured” and is graphed on the “y” axis.
Lay-out the “x” axis
Space out the number of bars evenly across the “x” axis.
Place bars in ascending order (lowest to highest).
Below each bar place a label.
Calculating the “y” axis SCALE:
Find the highest number in your data set.
Divide that number by the number of lines on the “y” axis =50 (if your paper is oriented “portrait”)
Take the quotient and ROUND-UP to the NEXT highest “NICE NUMBER TO COUNT BY”. Use this number to count the “y” axis scale all the way to the top of the graph.
Draw the Bars
USE A RULER to draw the bars.
Make sure the top of the bar is exactly where it belongs and it is FLAT.
Label each bar at the top with it’s value.
NEATLY shade in the bars as time allows.
