An independent variable is manipulated to determine the effects on the dependent variables. A true experiment is any study where an effort is made to identify and impose control over all other variables except one. The true experiment is often thought of as a laboratory study, but this is not always the case a laboratory setting has nothing to do with it. Experimental research, often called true experimentation, uses the scientific method to establish the cause-effect relationship among a group of variables that make up a study. ![]() When analyses and conclusions are made, determining causes must be done carefully, as other variables, both known and unknown, could still affect the outcome.Ĥ. Identified control groups exposed to the treatment variable are studied and compared to groups who are not. The researcher does not randomly assign groups and must use ones that are naturally formed or pre-existing groups. ![]() An independent variable is identified but not manipulated by the experimenter, and effects of the independent variable on the dependent variable are measured. These types of design are very similar to true experiments, but with some key differences. Causal-comparative/quasi-experimental research attempts to establish cause-effect relationships among the variables. *Sometimes correlational research is considered a type of descriptive research, and not as its own type of research, as no variables are manipulated in the study. Variables are not manipulated they are only identified and are studied as they occur in a natural setting. The data, relationships, and distributions of variables are studied only. Cause and effect is not the basis of this type of observational research. This type of research will recognize trends and patterns in data, but it does not go so far in its analysis to prove causes for these observed patterns. ![]() In this type of design, relationships between and among a number of facts are sought and interpreted. Correlational research attempts to determine the extent of a relationship between two or more variables using statistical data. Systematic collection of information requires careful selection of the units studied and careful measurement of each variable.Ģ. The analysis and synthesis of the data provide the test of the hypothesis. The researcher does not usually begin with an hypothesis, but is likely to develop one after collecting data. These research projects are designed to provide systematic information about a phenomenon. Descriptive research seeks to describe the current status of an identified variable. Present your findings in an appropriate form for your audience.ġ. Return to step 2 to form a new hypothesis based on your new knowledge. If not, the hypothesis has been proven false. If your prediction was correct, go to step 5. Formulate a plan to test your prediction. Make a prediction of outcomes based on your hypotheses.Hypothesize an explanation for those observations.Investigate current theory surrounding your problem or issue. Make your observations about something that is unknown, unexplained, or new.The basic procedure of a quantitative design is: It uses deductive reasoning, where the researcher forms an hypothesis, collects data in an investigation of the problem, and then uses the data from the investigation, after analysis is made and conclusions are shared, to prove the hypotheses not false or false. The overall structure for a quantitative design is based in the scientific method. What is the basic methodology for a quantitative research design?
