Chapter 18, Action Research. Mixed Research Design. True experiments, whilst giving analyzable data, often adversely influence the normal behavior of the subject. Subsequent experimental designs have used more groups and more measurements over longer periods. However, researchers can often begin their investigations far too early, before they have thought critically about about what information is required to answer the study's research questions.
