Research can either be experimental or no-experimental. Between the two research methods, experimental research is the most scientifically and also the most sophisticated research method. This makes the experimental be defined as observation that is under controlled conditions. Experimental research design method is concerned with examination of the effect of independent variable on the variable that is dependent. I this, the independent variable is manipulated via intervention or the treatment. The dependent variable is used in the effect of those interventions (Donald A., Lucy J., Asghar R. and Christine S. 2014). Accurate research done through experimental research must consist of the following features: manipulation, control and randomization. Whereby, manipulation refers to consciousness of the independent variable by the researcher. This is via the interventions or treatment of the dependent variable by observing its effect. Control on the other hand refers to the use of control group and controlling the effects of extraneous a variable on the dependent variable in which researcher is interested. Finally on the characteristics of experimental research method, randomization explains that, each subject has an equal chance of being assigned to experiment or to the study that is being carried out randomly.
The following is an example of experimental research question carried out. Assuming a certain researcher of a university wanted to know the effect of providing online feedback to students immediately after unit examinations. The researcher decides to make use of two groups of economics that were taught by the same lecturer, the researcher making use of a random method selects one group to receive feedback immediately through online means about the way they performed in the test then the other group is scheduled to receive their feedback

    The researcher doesn’t have full control over the environment in which the experiment takes place and cannot control any variables. This means that participants may not behave as they normally would. Because of this, the results may be affected which doesn’t show a valid representative of the research.…

    In an experimental research design the researcher is able to control the variables in the study, to determine how one variable affects another. In an ex post facto research design the variables cannot be controlled, and the researcher can only observe what is happening.…

    An experimental group is the group that will receive the protazen pill. This group is the one that will experience manipulation. On the other hand, the control group serves as a baseline for comparison; therefore, this group will receive a placebo pill. The placebo pill is an affect where participants will experience no physiological affect. The subjects in this experiment will be chosen by random assignment, so that every subject in the study has an equal chance of being placed in either the experimental or the control group. By choosing randomization it will help avoid false results. To avoid bias results in the experiment there will also exist the double-blind affect. This is an experimental design where neither the experimenter, nor the participants are aware of which participants are in the experimental or the control groups until results are calculated. This allows researchers to identify the specific effects of the independent variable, avoiding experimenter…

    An experiment establishes the relationship through manipulation of the study sample. For an accurate estimate of the relationship between variables, an experiment may need only tens of subjects. Experimental designs are often called true experimental research which can be identified by three characteristics: (1) pre-posttest design, (2) a treatment group and a control group, and (3) random assignment of study participants. Trochim, W. M. K., & Donnelly, J. P. (2008).…

    The second form of psychological research method is Experimental Design Research. This type of research is used to prove the causes of certain psychological problems. In the Experimental Design the researchers use as much control when presenting the variable as possible. The research presents the issue (variable) and then uses that variable in different situation, one may contain the variable and the other would not. The situation that is contained in the text is alcohol and date rape and in order to get a viable perspective and accurate results the researcher must present the dependent variable and the independent variable and with these the researchers manipulates the variables to see what the results…

    Experiments (or randomized controlled trials [RCTs]) involve manipulation (the researcher manipulates the independent variable by introducing a treatment or intervention); control (including use of a control group that is not given the intervention and represents the comparative counterfactual); and randomization or random assignment (with people allocated to experimental and control groups at random to form groups that are comparable at the outset). P. 232…

    Cause and effect experimental research involves a situation where a researcher manipulates a variable called an independent variable. Once that is done, he evaluates another variable called a dependant variable and checks to see if it reacts to the manipulated independent variable. If the dependant variable is reacting to the independent variable in a predicted way, than the researcher can conclude that the independent variable is the cause of the change of the dependant variable. This is the process of a cause and effect experimental research test. In a field experiment, subjects are observed in their natural outdoor environment so that researchers can study their behavior. Most of the time, the subjects are not aware of the researchers and so usually the conclusions are mostly accurate. For example, researchers may follow lions and research how they live, eat, breed and also migrate in order for them to stay close behind on their prey. As long as the researchers are not interrupting the lion’s routine, their findings should be highly accurate. The drawback to this experiment is that the researchers have little to no control of the experiment if something happens. The last experiment is a laboratory experiment. This is where a subject is put in a controlled environment so that the researcher can manipulate the setting and see if it causes any reaction in the subject. The advantage to this research is that the researcher has a high amount of control of the setting so that he or she can manipulate the environment and way they see fit in order to get a response from the subject. One example could be putting a subject in a empty room and administer different drugs to him to see what would be the results. Since the room is empty and nothing can interfere with the subject, the researchers can monitor the subject closely and record accurate readings since there are…

    All sociological researchers make use of the data collected to test their hypotheses, but the way and methods used differ from one sociological study to another. There are four general techniques, the case study, the experiment, the observational study and the survey. An experiment is a scientific method in which data are collected to be tested to prove a hypothesis using either independent variables in a closed environment or dependent variables in an opened environment.…
