An experimental research design uses quantitative procedures to determine whether an activity or materials (an intervention) make a difference for participants. Two groups are formed: a control group and an experimental group. The experimental group receives the intervention and the control group does not. The performance of each group is assessed by measuring key variables and the measurements are compared statistically to see if the intervention made a difference.

An experimental research design uses quantitative procedures to measure the relationship between two or more variables using the statistical procedure of correctional analysis. This research design allows researchers to explain and predict the relationship among variables. Researchers do not attempt to control or manipulate the variables.
Pages 20-22 and Chapter 12.
An experimental research design uses quantitative procedures to describe trends in data rather than offering rigorous explanations. Researchers collect data quantitative data using questionnaires or interviews and statistically analyze the data. Surveys are given to a sample population to describe attitudes, opinion, behaviors, and characteristics of the population. The focus is directed at learning about a population and less on how variables relate or outcome predictions.
Grounded Theory Designs
Pages 20-22 and Chapter 13.
An experimental research design uses qualitative procedures that generate a theory when existing theories do not address your plan of study or participants. This design provides a systematic process for analyzing data to explain an educational process of events, activities, action, and interactions that occur over a span of time. Researchers identify and connect the categories to
