Prof. Gersch's brother, often wondering why Prof Gersch goes through all the trouble of collecting random samples for his analysis, figures that it would be a lot easier to just stand in the lobby of Pace and ask the first fifty passers-by about their height. Prof. Gersch's brother collected a: Cluster Sample Convenience Sample Stratified Sample Snowball Sample Probability Sample Even for a well-collected sample, a good statistician should be aware of: the wording of questions in the study the wording of answers in the study non-response and missing data undercoverage of some part of the population biases that may be present in the research all of the above The Central Limit Theorem (CLT) states: that the distribution of mu becomes more normal as the sample size increases that the distribution of.v becomes more normal as the sample size increases that the distribution of p becomes more normal as the sample size increases that the t distribution becomes a z distribution as the sample size increases that the t distribution becomes a z distribution as the degree of freedom increases
