Tips to Remember:
Guidelines to Writing Survey Questions
-
Ask questions only if the
answers will give you the information that
you can use.
-
Make the questions so that
the answers will be in the form for your
purposes.
-
Write in everyday terms
that will express your idea.
-
Do not tell your opinions,
use neutral wording.
-
Ask only one thing at a
time.
-
Your questions should be
short, simple, clear, and to the point.
Be sure to use correct spelling, grammar,
and language usage.
-
If you use scales, for
example rating something from 1 to 5, be
sure to use the same rating scale throughout
your survey.
-
Think about the answers
your questions will receive. They need
to provide you the information need.

Red Flags in Survey Questions
-
The word "and" usually
means that the question may have two
or more questions within. Be careful
using the word "and".
-
Stay away from long questions.
-
Using the word "if" seems
to lead to confusing directions. Be careful
using the word "if" in your
questions.

Collecting Data
-
Know precisely the information
you are looking for.
-
Be sure to gather from a large
enough sample so the information you get represent
a large number of people. Asking just one
or two people won't get you the results you
need. The more people you are able to ask
the better your results and the information
you are looking to find.
-
Make sure that when you
collect data, you ask a random sampling
of people. In other words, don't just
ask all boys in one classroom, but be
sure to ask boys and girls from as many
different classes as you can.
