Sampling is the process of selecting a representative subset of observations from a population to
determine characteristics (i.e. the population parameters) of the random variable under study.
Probability sampling includes all selection methods where the observations to be included in a
sample have been selected on a purely random basis from the population. Briefly explain FIVE (5)
types of probability sampling.

Sampling is the process or technique of selecting a suitable sample for the purpose of determining the parameters or characteristics of the whole population. To carry out a study, one might bear in mind what size the sample should be, and whether the size is statistically justified and lastly, what method of sampling is to be used. Analyze any TWO (2) differences between stratified random sampling and cluster sampling.

Which situation most commonly leads to convenience, availability, or accident sampling? When the researcher wants to maximize the likelihood that the sample is representative of the population from which it is selected. When the researcher is knowledgeable about the study topic and wants to make sure that the sample includes particular types of members. When the researcher is friendly with a few “informants” in the hypothetical population who can help locate other members best suited for the study, often those...

PART 1: Sampling How we select our sample will directly influence the external validity of the study. If a sample is representative, then our external validity is stronger. If a sample is non-representative, then our external validity is weaker. QUESTIONS: 1.
