What is a Simple Random Sample?
« on: April 13, 2016, 10:28:24 AM »
A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen. A simple random sample is meant to be an unbiased representation of a group. An example of a simple random sample would be a group of 25 employees chosen out of a hat from a company of 250 employees. In this case, the population is all 250 employees, and the sample is random because each employee has an equal chance of being chosen.

In simple random sampling, if population is 250, then minimum sample size suppose to be 152 with 5% margin of error.

For random sampling , researchers should focus on this formula and the table available in those documents.
