Which research method is the only method that can establish cause and effect?
|
Experimental research is research conducted with a scientific approach using two sets of variables. The first set acts as a constant, which you use to measure the differences of the second set. Quantitative research methods, for example, are experimental.

If you don’t have enough data to support your decisions, you must first determine the facts. Experimental research gathers the data necessary to help you make better decisions. Any research conducted under scientifically acceptable conditions uses experimental methods. The success of experimental studies hinges on researchers confirming the change of a variable is based solely on the manipulation of the constant variable. The research should establish a notable cause and effect. You can conduct experimental research in the following situations:

The way you classify research subjects, based on conditions or groups, determines the type of research design you should use. 1. Pre-experimental research design: A group, or various groups, are kept under observation after implementing factors of cause and effect. You’ll conduct this research to understand whether further investigation is necessary for these particular groups. You can break down pre-experimental research further in three types:
2. True experimental research design: True experimental research relies on statistical analysis to prove or disprove a hypothesis, making it the most accurate form of research. Of the types of experimental design, only true design can establish a cause-effect relationship within a group. In a true experiment, three factors need to be satisfied:
This experimental research method commonly occurs in the physical sciences. 3. Quasi-experimental research design: The word “Quasi” indicates similarity. A quasi-experimental design is similar to experimental, but it is not the same. The difference between the two is the assignment of a control group. In this research, an independent variable is manipulated, but the participants of a group are not randomly assigned. Quasi-research is used in field settings where random assignment is either irrelevant or not required.

Experimental research allows you to test your idea in a controlled environment before taking it to market. It also provides the best method to test your theory, thanks to the following advantages: 
Whether you want to know how the public will react to a new product or if a certain food increases the chance of disease, experimental research is the best place to start. Begin your research by finding subjects using Which method of research is causeCausal research, is the investigation of (research into) cause-relationships. To determine causality, variation in the variable presumed to influence the difference in another variable(s) must be detected, and then the variations from the other variable(s) must be calculated (s).
Which type of study is most effective at establishing causeRandomized controlled trials provide the best results when trying to find out if there is a cause-and-effect relationship. RCTs can answer questions such as these: Is the new drug A better than the standard treatment for medical condition X?
What is the only method of research that allows researchers to determine cause?While there are a number of different research techniques available, the experimental method is one that allows researchers to look at cause-and-effect relationships.
Which type of research design is best when you want to make a causeA randomized experiment generally is the strongest of the three designs when your interest is in establishing a cause-effect relationship.
