Repeatability

From the National Institute for Standards and Technology, the definition of repeatability is "closeness of the agreement between the results of successive measurements of the same measurand carried out under the same conditions of measurement." This is a concept we deal with a lot as engineers and basically means your results are true when you can make it do the same thing over and over again.

Well, yesterday, to demonstrate to Daddy that I'm not crazy. I had Zara in the pack 'n play and got her to roll over from tummy to back 5 consecutive times. So she is rolling over and easily, but it is a location dependent event. I think it has to do with being on her tummy in the pack n play where she can't see anything. John alleges that since the pack 'n play is 'softer' (not really its just a thin pad in there, not a trampoline), she isn't really rolling over. I'd like him to break out the durometer and determine which surfaces qualify for the rolling over test then.

This concludes my geeked out baby analysis today.
