Document Summary

Baskets of term/items to know for test: sample mean (x with line over it) (latin, mode, median, sample standard of deviation and formula, range, bar/histogram graph, represented sample, random sample, notation, = sum. = (x- )2/n: n = size of population (used in population mean calculation above, population standard deviation formula which is a measure of variability. If all numbers the same- variability is the same: data different forms (e. g. , ages, salary, # of kids, nominal aka qualitative the nominal scale is a type of measurement scale. Values assigned to variables represent a descriptive category, but have no inherent numerical value with respect to magnitude. If skewed to the right, mean will be larger than median: formula relative frequency. Portion of measurement (percentage) to left of the decimal point: leaf - corresponding row in second column to the right of corresponding stem number.
