First ask: How many people responded to the survey? Next, ask: How many people gave each answer to a question?
Then for each possible response, divide the number of responses by the total number of people who responded to the survey. If you do this on a calculator, you can generally round your answer to two decimal places. If you remove the decimal, now you have a percentage.
Example: A sample survey given to clients of Axl Healthcare included the following question: How would you rate the offerings in the convenience store? (circle one)
good
excellent
poor
below average Your count says 65 people completed the survey.
On this question, 41 answered “excellent;” 12 answered “good;” 6 answered “average;” 4 answered “below average;” and 2 answered “poor.” Your summary shows: Excellent:
Good: Average:
41 ÷ 65 = 0.6308 or about 63% 12 ÷ 65 = 0.1846 or about 18% 6 ÷ 65 = 0.0923 or about 9%
Below Average: 4 ÷ 65 = 0.0615 or about 6% Poor:
Total Responses: 99%
Note: The total percentages add up to 99% due to rounding; i.e., 0.0923 was converted to a percentage by multiplying by 100 (9.23%), then rounded to 9%.
