This chapter investigates how to analyze and draw conclusions based on gathered data. This is also also known as statistical studies. Further, concepts like sampling, bias, randomization, and margin of error are introduced.
Statistical studies is a way to analyze gathered data from a population to answer different questions about the group. This is carried out by different methods such as collecting responses or observations from interviews or counts etc.
The chapter also discusses the issue of bias. When collecting a sample, it is necessary that the observations are collected in an unbiased fashion. There are different ways of accomplishing this to keep the selection randomized. This is because the sample should be representative of the population which allows us to then draw conclusions about the population depending on the sample. This means the selection of the sample is very important.
