Four Components Of An Experimental Method Plan In Experimental Planning

In a laboratory study of sleep deprivation, researchers employed a variety of techniques to keep

Box 3.2: Why do it this way? is especially relevant, as it considers an important advantage of the experimental method. Chapter 6: No experiments are discussed in this chapter, however, the essay question requires you to discuss the value of experiments. Consider if there are certain aspects of human behaviour and/or performance that cannot be meaningfully investigated using experiments. What are the alternative methods of studying behaviour? Sections 2 and 3 of Chapter 6 are relevant in this respect.

f. Specify with diagrams and justify which methodology would be more appropriate? Methodology used in part ‘a’ or in part ‘e’. What are the names of these respective methodologies?

Instructions: This is a group activity that you will start in class and complete at home. For each of the following, note, whether the research design used is an experiment, a quasi-experiment, or a correlational approach and why. If a study is an experiment, identify the independent variable and the dependent variable. Please type your answers in complete sentences.

3. A _(B) Small n design has many observations on a single case or a few subjects.

Materials and methods describe the resources used in the experiment and how it was performed. Reading the methods of previous studies enables scientists to repeat the experiment and collect their own data. This data can be used to support other’s findings.

19. The text points out a common misconception about the term “controlled experiment”. In the

Quantitative and qualitative methods differ from one another as to their research design elements as listed below:

What is the research method (i.e.: survey, participant observation, experiment, secondary sources) used by the researchers?

One known research method is the Scientific Method which is a uniform way of creating observations, assembly data, establishing concepts, testing predictions, and understanding outcomes. These observations are made in order to observe and define behaviors. The first step to take in using a scientific method is to develop an issue or question. Next step is to perform a research and observation on the issue or question that was developed. Then a hypothesis needs to be formulated after these steps have been made.

b. Sample selection techniques and control of constant variables (e.g. Are samples randomly selected. What attempts are made to control variables).

In any mixed methods study, you should clearly indicate that you are collecting both quantitative and qualitative data. Methods of data collection are typically associated with either numbers or numeric data and words or text and image data. Mixed methods researchers collect both quanti­tative and qualitative data.

According to Hair et al. (2003), in the research, the sampling process enables identifying, developing and understanding an interested object that need to be determined (p.333). Hence, in order for the researcher to carry out the sampling appropriately, advantages and disadvantages of the various sampling methods should be considered along with the theoretical component of the study (Hair et al. 2003, p. 368 f). Theoretically, the sampling procedure is divided into two major types which consist of probability and nonprobability sampling. In probability sampling, individuals have a known chance of being selected. While, in non-probability sampling, individuals do not have a known possibility to be selected (Sekaran 2003, p. 269 f). Also, the different sampling methods provide different advantages and disadvantages. Hence, the researcher should consider this point before choosing the sampling method for the

Quasi-experimental research, which was once considered ‘flawed’ and less superior to true experimental research, has become increasingly popular over the last three to four decades in many areas, especially the social sciences (Coolican, 2014, p. 121). It differs from true experimental research design in the way that quasi-experimental research doesn’t involve random assignment of participants to groups and often has less control over the independent variable (Follmer Greenhoot, 2003, p. 94; Coolican, 2014, p. 121). An

A study design is the procedure that guides a researcher on how to collect, analyze and interpret observations. It is a logical model that guides the investigator while he navigates through the various stages of the research. Study types can be classified severally depending on the research strategy employed. A study type can be non-interventional that is ‘observational’ where a researcher just observes and analyses researchable objects or situations without intervening. Non-interventional study designs can be exploratory, descriptive or comparative. A study can also be
