The teachers are then randomly selected to teach one of the classes. At the end of the course, all students take the same exam and the grades for the two classes are compared. Comment on the design of this experiment. 9. Design a study comparing student scores on a standardized test after using two different types of textbooks. 10.

The study design is dependent on the question asked, the theoretical model, and the type of analysis that will be applied. This phase is a reflection of what is already known (methodologically & conceptually) and it functions as a method for collecting data that can contribute to the development of a theoretical model.

Non-experimental design. Without the use of a comparison or control group, has little control over the factors that affect the validity of the results. The most powerful design is the experimental design, in which participants are randomly assigned to the experimental and control groups. The difference between I.1.

The design of the experiment should be such that the effect of other factors is limited or controlled. Comparison of the test and control group allows us to determine the extent of the change that is due to the independent variable only. This type of experimental design is called the ‘after with a control group’.
Introduction
She decided to investigate the response of bees to five different perfumes- Ralph Lauren, Armani, Mark Jacobs, Vera Wang, and the last is an odorless liquid. She placed a saucer containing 20ml of perfume A 10 meters from a beehive.

This is the classical type of experimental design and has good internal validity. The external validity or generalizability of the study is limited by the possible effect of pre-testing. The Solomon Four-Group Design accounts for this. Solomon Four-Group Design
