WHAT does this mean??--statitstic validity?

Question

HELP!

Answer 1

I'll put it in an example: If you are conducting an experiment, and you want it to be accurate (valid), you need lots of data (such as statistics). An experiment conducted on mice would have to have many, many mice to have statistical validity, because if there weren't enough mice, the results wouldn't be consistent every time you performed that experiment. Another example: In the case of a poll or survey, a random, diverse, and numerous group of people must be interviewed to have statistical validity. For instance, you can't discern the average height of high schoolers just by measuring 5 people.
I hope you get it - it's kind of a difficult concept, at least, the way I explained it.

Answer 2

You must be able to prove your information. Through an encyclopedia,an atlas or something of this sort
