Document Summary

Provided blank by instructor, fill out yourself as practice, tweaked by my preferences) Distinguishing characteristics properties of the scale of measurement. Categories/labels of data (if numbers are used to represent variables, numbers do not have any numerical value) 3rd) (still no degree of difference between variables) [1 and 2 do. Not have 1 unit a part from each other, order 1,2,3 is arbitrary] Equal units (there is a degree of difference between items, but no ratio cuz there is no true 0, 40 c is not twice as hot as 20 c) Range, sd etc, coefficient of variation yes mhm yis si se or. Distribution of a population of scores: xi ~n( x, x2) Inferential statistics: use sample characteristics to make inferences about population"s characteristics. Hypothesis testing: use an observed sample statistic to estimate population parameter. Mean is the expected value of that statistic over repeated sampling.
