Determine the objectives
Delimit the sample
Construct the questionnaire
Conduct the pilot study
Establish the distribution process
Analyze the data
1 st pilot – colleagues, peers
2 nd pilot – participants who are part of the intended population
What are we looking for?
Look for:
Questions that lack discrimination
(answered the same by all)
Unexpected responses
May be poorly worded
Questions people don’t respond to

Each question structure implies a
“scale of measurement”
Likert, semantic differential, etc.
Scales guide statistical analysis

Nominal Scales
Ordinal Scales
Interval Scales
Ratio Scales
Lowest level of measurement
Words & not # values….not a rating
Each value defines a distinct category
Needs to be coded for Excel/SPSS
Example…..
_____ (1) Male _____ (2) Female
Other examples
2. What was your favorite activity?
(pick one)
___ Golf ___ Soccer ___Baseball
___ Golf (1) ___ Soccer(2) ___Baseball (3)
3. Have you attended this program previously?
___Yes ___No
Unordered close-ended
Implied rank or order
Each category has a position higher than the previous
Distance between categories isn’t equal
Ie. 1st, 2nd and 3rd place
Example
AP Basketball poll
Ordered categories have meaningful size differences or distance between values
Distance between intervals is equal
Does not have a determined zero point
Distance makes sense, ratios don’t
Calendar year
2011 ---365 days ---2012 ----365 days ---2013
Outdoor temperature
Thermometer – degree increments are equal
Is 0 ° as cold as it gets?
100 degrees isn’t twice as hot as 50
Meaningful size differences and equal distances (unlike ordinal)
Likert scales…
Likert scales
Some believe ordinal
Categorical with order
Others believe interval
Ordered categories have meaningful size differences
What is the difference between strongly agree, and agree….and is that difference the same as the difference between agree and neutral?
Likert scales
Argument for interval
If there is symmetry in the responses
SA/A/N/D/SD
E/G/F/P – not symmetrical, uneven distances between categories
Has a true zero point
Makes ratios possible
Has ordering & distancing properties of interval
Weight
100 lbs. Is twice as heavy as 50 lbs.
Reaction time

Scale of measurement? Why?
Would you rephrase the question? Why?
How we ask the question may limit us
Scales of measurement have range from the least precise to the most precise
Nominal Ordinal Interval Ratio
Determines what statistics are possible
Nominal is most limiting ; yes/no questions
56% enjoyed the show, 44% did not
Why change YES/NO questions to Likert?
Degree of interest/opinions/attitudes
With ordinal, interval, and ratio we can compute averages and measure variability
Developing a Codebook
Before entering data into computer
Instructions on converting data
Details how to define & label each variable
Assign #’s (codes) to responses
List every variable…including the ID #
2. What is your current grad school sequence?
______ Athletic Training
______ Biomechanics
______ Exercise Physiology
______ Physical Education Teacher Education
______ Psychology of Sport & Physical Activity
______ Recreation Administration
______ Sport management
