Standard distribution is assumed as above formula. Thanks a lot for the reference. Get notified when new articles including pbs sample are posted. Of the five methods listed above, students have the most trouble distinguishing between stratified sampling and cluster sampling. Therefore the data i used above is taken exactly from the survey from students. We neglect the factors like genetic, races and sex iv. But I would like to ask about my test statistic.

The probability of success, p, is assumed to be constant for each family member. Below are parts of the data collected. It is important to note that, unlike with the strata in stratified sampling, the clusters should be microcosms, rather than subsections, of the population. With p known or p unknown? Each family member trial has two outcomes; wearing glasses and not wearing glasses. Non-probability Sampling The following sampling methods that are listed in your text are types of non-probability sampling that should be avoided: The number of restrictions is 2 when the parameter is unknown.

I have conducted survey on the number of family members wearing glasses in 5-member families. The sample values are independent of each other. Sampling Methods can be classified into one of two categories: Scroll down for all the sample answers and solutions.

I calculated it by applying binomial distribution formula but I dont seem to be able to obtain the same answer as yours after several attempts. If you need further explanation, please google.
