Week 4 Overview

Welcome to Week 4!
In the first half of the course, you learned that scientific investigation proceeds by iterations of observation, explanation, and experimentation. This week, we dig deeper into one aspect of observation, sampling. Sampling is one of the techniques for gathering the data on which theories are built.
Sampling is a vital part of research. It can make or mar a study. An error or bias in sampling could produce questionable data and lead to erroneous conclusions. Suppose you want to investigate the health effects of weight training. It may seem that the sample should be drawn from people who do weight training. However, you must include in your sample some people who do different types of exercise and some who do not exercise at all. Only this type of a sample will allow you to compare the health status of those who work out with weights and those who don’t. Not only are the groups considered for each research important, the sample size is also extremely important. Suppose you selected 20 individuals out of a population of 2,000. This is only 1% of the population and may not be a representative sample.
