Jamie has written seven books and co-authored one. The conception, implementation, advantages, disadvantages and possibilities of using the different study types are illustrated by examples.

Three main areas are distinguished: There are three main types of descriptive methods: Questions should be written so they are clear and easy to comprehend.

Open-ended questions allow for a greater variety of responses from participants but are difficult to analyze statistically because the data must be coded or reduced in some manner.

Descriptive research methods are pretty much as they sound — they describe situations. The article focuses on study types in primary research.
