STA 1053 Study Guide - Final Guide: Interquartile Range, Blind Experiment, Response Bias
Document Summary
Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate. Determine which type of sampling is used: random, stratified, systematic, cluster, or convenience. Types of sampling: simple random sample. Probability sampling methods (those that use a random mechanism: systematic random sampling, stratified random sampling. Find the measures of center (mean, median, mode, and midrange) of the following data. Know graphs and which ones you use for data. Find the mean and standard deviation for binomial distribution. For the standard normal distribution, find the probability of a zscore. Use standard normal table to find z score. Find given confidence interval for the population mean. Find the point estimate and the margin of error. Given the sample statistics, determine if you should use the t distribution, normal distribution, or neither to construct a confidence interval to estimate population mean:
