That means the final data set would not be a random representative of the entire group because it would over-emphasize the nature of the periodic trait. The process of selecting a sample from a population without using statistical probability theory is called non probability sampling. sharing sensitive information, make sure youre on a federal The members are picked in view of the reason for the Sample, consequently the name. A common form of voluntary sampling is the customer satisfaction survey. So, intensive and exhaustive data are collected.
