Experimental research designs are considered the standard for research. They involve assigning one or more dependent variables to different treatments and observing the results to draw conclusions. Experimental research has both advantages and disadvantages. It allows full researcher control but can be resource-intensive. It aims to determine relationships between dependent and independent variables by supporting or rejecting hypotheses. Data must be quantifiable and include measurements of variables like area, weight, temperature etc. Qualitative observations also supplement the research. Overall, experimental research uses a scientific approach to test business matters and understand customer behavior through product testing and experiments.
