MSIT FINAL EXAM 2 STUDY GUIDE
TEST.
simulation - CORRECT ANSWER when we use a computer to pretend to draw random samples from
some population of values over and over
sampling distribution of the sample proportion - CORRECT ANSWER the distribution of the sample
proportion over many independent samples from the same population
standard error - CORRECT ANSWER the standard deviation of the sampling distribution. measures how
much the sample proportion may typically vary from one sample to the next, as well as how far it may
typically be from the true population proportion
independence - CORRECT ANSWER the sampled values must be independent of each other. there should
not be any common factors such as the same family, group of friends, snowstorm affecting everyone in
the region. In practice, this condition will usually be satisfied
randomization condition - CORRECT ANSWER if your data came from an experiment, subjects should
have been randomly assigned to treatments. If you have a survey, your sample should be a simple
random sample of the population, or some other unbiased sampling method
10% condition - CORRECT ANSWER if sampling was done without replacement, then the sample size, n,
must be no larger than 10% of the population
sample size - CORRECT ANSWER the sample size, n, must be large enough
