Question

provides examples of experimental and non experimental research design. Contrast the levels of control applied to each

Answer 1

• Experimental research is a quantitative research method
• non-experimental research can be both quantitative and qualitative depending on the time and the situation where it is been used.
• A example of a non-experimental quantitative research method is correlational research.
• The example of experimental research is laboratory experiments, which may differ in nature depending on the subject of research
• In experimental research the use of random assignment of subjects attempts to eliminate systematic bias. Random assignment is different from random sampling. Random sampling means that each subject had an equal chance of being selected from a larger group to participate in the study

Contrast

• In an experimental design, the researcher actively manipulates one or more variables.
• nonexperimental design the researcher explores relationships or differences among the variables.
• An experimental design can have a control group, but the control is not manipulated but naturally occurring.
