A confounding factor in a study is a variable which is related to one or more of the variables defined in a study. A confounding factor may mask an actual association or falsely demonstrate an apparent association between the study variables where no real association between them exists. If confounding factors are not measured and considered, bias may result in the conclusion of the study.

Nice hair! I must say, except for the hair, you still look like you did back in 84! Since I graduated in 82 and got married in 83 I was probably pregnant in 84...at least at the end of the year...oh my....time passes quickly! Oh yes....and living in a 14x60 mobile home on the UND college campus!
Oh....and I should have mentioned the music....I was listening to Keith Green (who had already died in the airplane accident) on my turntable.
But hey.....some things haven't changed.....I was listening to Keith Green last night.....only on my tiny little Ipod shuffle...how did they fit my LPs in that tiny little thing??? :)
