Surveying, Calculating Percentages, & Graphing
Mr. Mitchell’s Social Studies
Designing and Implementing a Survey:
1. Write a question that can be easily answered. Ex: How many TV’s do you have in your residence?
2. Create a table to enter the data/answers collected. Ex:
# Participants |
0 |
1 |
2 |
3 or more |
IIII (etc. to 25) Need at least 25 participants for real survey |
- |
III |
IIII (etc. to 17) |
IIIII |
Total 25 |
- |
3 |
17 |
5 |
Calculating Percentages:
1. Once you’re finished surveying, divide each column total by the total of participants. Ex: If 17 people answered that they had two TV’s in their house, the equation would look like: 17/25 = 0.68
2. Then convert the answer to a percentage by moving the decimal over two places to the right. Ex: 0.68 = 68%
Graphing your results:
1. Go to the website: http://nces.ed.gov/nceskids/graphing/
2. Click “Start Making Graphs”
3. For this assignment, choose Pie Graph.
4. Choose the way it will look – understand that the printed copy from school will be in black and white. (Patterns work better here)
5. Click the “Data” tab on the right.
6. Title = Your question you asked.
7. Source = Survey of KOMS students
8. Pie Slices = How many types of answers/choices you gave.
9. Item label = The titles of each. Ex: “3 or more”.
10. Value = Enter the percentage for each column.
11. Click “Label”
12. Type = “% of total” Leave all else as is on this page.
13. Click “Preview” (Make sure it matches your results.)
14. Click “Print/Save”. Then print it! You can get Adobe Acrobat from my Helpful Downloads page.
