Detailed explanation-1: -Simple random sampling is a type of probability sampling in which the researcher randomly selects a subset of participants from a population. Each member of the population has an equal chance of being selected. Data is then collected from as large a percentage as possible of this random subset.
Detailed explanation-2: -Definition: Random sampling is a part of the sampling technique in which each sample has an equal probability of being chosen. A sample chosen randomly is meant to be an unbiased representation of the total population.
Detailed explanation-3: -A simple random sample takes a small, random portion of the entire population to represent the entire data set, where each member has an equal probability of being chosen. Researchers can create a simple random sample using methods like lotteries or random draws.
Detailed explanation-4: -What Is a Sample? A sample refers to a smaller, manageable version of a larger group. It is a subset containing the characteristics of a larger population. Samples are used in statistical testing when population sizes are too large for the test to include all possible members or observations.
Detailed explanation-5: -1. Random Sampling: In the random sampling method each individual in the population has an equal chance of being selected in the sample. This method is used in a homogeneous population and the selection of one sample does not affect the selection of the previous sample.
