Experimental Research It is a collection of research designs which use manipulation and controlled testing to understand causal processes. Generally, one or more variables are manipulated to determine their effect on a dependent variable. The experimental method is a systematic and scientific approach to research in which the researcher manipulates one or more variables, and controls and measures any change in other variables. Experimental Research is often used where: There is time priority in a causal relationship (cause precedes effect) There is consistency in a causal relationship (a cause will always lead to the same effect) The magnitude of the correlation is great. The word experimental research has a range of definitions. In the strict sense, experimental research is what we call a true experiment. This is an experiment where the researcher manipulates one variable, and control/randomizes the rest of the variables. It has a control group, th...

Descriptive Research Focused towards the present Gathering information and describing the current situation May or may not involve hypothesis testing Answers the question “What is?” Many types of research fall within this classification Descriptive research does not fit neatly into the definition of either quantitative or qualitative research methodologies, but instead it can utilize elements of both, often within the same study. The term descriptive research refers to the type of research question, design, and data analysis that will be applied to a given topic. Descriptive statistics tell what is , while inferential statistics try to determine cause and effect. The type of question asked by the researcher will ultimately determine the type of approach necessary to complete an accurate assessment of the topic at hand. Descriptive studies, primarily concerned with finding out "what is," might be applied to investigate the following questions: Do te...
