This lesson describes two important types of data sets - populations and samples. Along the way, we introduce simple random sampling, the main method used Composed of two groups - target population & accessible population Sampling frame = a list of all the elements in the population from which the sample is Population Sampling Techniques. Population sampling is the process of taking a subset of subjects that is representative of the entire population. The sample must have sufficient size to warrant statistical analysis. The field of inferential statistics enables you to make educated guesses about the numerical characteristics of large groups. The logic of sampling gives you a. In statistics and quantitative research methodology, a data sample is a set of data collected and/or selected from a statistical population by a defined procedure. The elements of a sample are known as sample points, sampling units or observations. The population is the set of entities under study. For example, the mean height of men. This is a hypothetical population because it includes all men A well chosen sample will contain most of the information about a particular population parameter but the relation between the sample and the population must In applied statistics, we have to differentiate strictly between populations and samples. Consider a box containing 500 balls of three different colors. This set of
