STAT 246 Lecture Notes - Lecture 1: Sample Size Determination
Document Summary
Cumulative probability - proportion of observations in the distribution that lie at or below x. Standardizing the value of x, also known as z-scores if. Standardizing the value of (cid:1876) , also known as z-scores (cid:1876) . Sd of (cid:1876) = (cid:1876)= + (cid:1876) = (cid:1840)(cid:4666) , (cid:1866) (cid:4667) =(cid:1876) / (cid:1866) (cid:1868) =(cid:1868) (cid:1840) (cid:4666) =(cid:1866)(cid:1868), = (cid:1866)(cid:1868)(cid:4666)(cid:883) (cid:1868)(cid:4667) (cid:1840) (cid:4666) (cid:1868) =(cid:1868), (cid:1868) = (cid:1868)(cid:4666)(cid:883) (cid:1868)(cid:4667) (cid:4667) (cid:1866) (cid:1840)(cid:4666)(cid:1868), (cid:1866)(cid:1868)(cid:4666)(cid:883) (cid:1868)(cid:4667) (cid:4667) (cid:1866) When population is at least 20 times larger than population size, Statistic - number that can be computed from the sample data without making use of any unknown parameters. Standardizing the value of and with an unknown , also known as z scores.
