Caution: Survey Ahead!

Lots of health data comes from surveys. Here are some issues to consider when looking at survey or estimated data:

Look at sample sizes and survey response rates - representative of your population? Enough responses to be valid?
Who was surveyed? - representative of population being compared to? Include group you are interested in?
Were the survey respondents from heterogeneous groups? Do the survey questions have a similar meaning to members of different groups?
How was survey conducted? Via telephone? - Many people only have cell phones. Random selection or targeted group?
What assumptions and methods were used for extrapolating the data?
Look at definitions of characteristics - Does this match your own definitions?
Who identified race/ethnicity of respondents/participants?
When was the data collected? Who collected it?

(Adopted from information on the UCSF Family Health Outcomes Project web site, and from How to “QuantCrit:” Practices and Questions for Education Data Researchers and Users)

Reliability and Validity

Reliable data collection: relatively free from "measurement error."

Is the survey written at a reading level too high for the people completing it?
Is the device used to measure elapsed time in an experiment accurate?

Validity refers to how well a measure assesses what it claims to measure

If the survey is supposed to measure quality of life, how is that concept defined?
How accurately can this animal study of drug metabolism be extrapolated to humans?
