Document Summary
293: parameter: a fixed number that describes the population, statistic: a number that describes a sample, the value of a statistics is known when we have taken a sample, but it can change from sample to sample. Drawing a simple random sample using random digit table pg. 295: suppose we have a population of 80 students, numbered 1 ~ 80, want a simple random sample of 6 of them. Drawing a stratified sample: suppose we have a population of 100 students, numbered 1 ~ 60 females and 61 -99 and 00 male. Simple random sampling: # of every single word and the n sample from them. 10 words on each page: this is easier since you select a particular page and other words on the same page may more likely to be in the sample too, this is called cluster sampling.
