1st Step: List and explain the Steps of the Scientific Method, then define the (10) scientific terms with an example (refer to attachment)Experimental Research Study Essay
2nd Step: Develop an Experimental Research Study using the scientific principles listed in step 1. Use any topic of interest (e.g., extracurricular activity, hobby or career interest). Make it simple! (Refer to Scientific Method attachments and the PPT slide 16-23 only).
3rd Step: Describe the Descriptive Research Study on the Milgram Experiment in a 1 page essay format: (Refer to link below)
You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes.Experimental Research Study Essay
Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages.
Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor.Experimental Research Study Essay
Experimental Research
Definition:
Experimental research is any research conducted with a scientific approach, where a set of variables are kept constant while the other set of variables are being measured as the subject of experiment. There are times when you don’t have enough data to support your decisions. In such situations, you need to carry out experiments to discover the facts. Experimental research can gather a lot of data that can help you make better decisions.
Experimental research is one of the founding quantitative research methods.Experimental Research Study Essay
The simplest example of an experimental research is conducting a laboratory test. As long as research is being conducted under scientifically acceptable conditions – it qualifies as an experimental research. A true experimental research is considered to be successful only when the researcher confirms that a change in the dependent variable is solely due to the manipulation of the independent variable.
Experimental research should establish a cause and effect of a phenomenon, i.e. effects are observed from an experiment due to the cause. As naturally, occurring event can be confusing for researchers to establish conclusions. For instance, if a cardiology student conducts research to understand the effect of food on cholesterol and derives that most heart patients are non-vegetarians or have diabetes. They are aspects (causes) which can result in a heart attack (effect). Experimental Research Study Essay
Experimental research is conducted in the following situations:
- Time is a vital factor for establishing a relationship between cause and effect.
- Invariable behavior between cause and effect.
- The eminence of cause-effect relationship is as per desirability.
Types of Experimental Research Design
There are three primary types of experimental research design:
- Pr-experimental research design
- True experimental research design
- Quasi-experimental research design
The different types of experimental research design are based on the how the researcher classifies the subjects according to various conditions and groups.
1. Pr-Experimental Research Design: This is the simplest form of experimental research design. A group, or various groups, are kept under observation after factors are considered for cause and effect. It is usually conducted to understand whether further investigation needs to be carried out on the target group/s, due to which it is considered to be cost-effective.

The per-experimental research design is further bifurcated into three types:
- One-shot Case Study Research Design
- One-group Pretest-post test Research Design
- Static-group Comparison
2. True Experimental Research Design: True experimental research is the most accurate form of experimental research design as it relies on statistical analysis to prove or disprove a hypothesis. It is the only type of Experimental Design that can establish a cause-effect relationship within a group/s. In a true experiment, there are three factors which need to be satisfied:
- Control Group (Group of participants for research that are familiar to the Experimental group but experimental research rules do not apply to them.) and Experimental Group (Research participants on whom experimental research rules do apply.)Experimental Research Study Essay
- Variable which can be manipulated by the researcher
- Random distribution
This experimental research method is commonly implemented in physical sciences.
3. Quasi-Experimental Research Design: The word “Quasi” indicates resemblance. A quasi-experimental research design is similar to experimental research but is not exactly that. The difference between the two the assignment of a control group. In this research design, an independent variable is manipulated but the participants of a group are not randomly assigned as per conditions. The independent variable is manipulated before calculating the dependent variable and so, directional problem is eliminated. Quasi-research is used in field settings where random assignment is either irrelevant or not required.Experimental Research Study Essay
Advantages of Experimental Research
- Researchers have a stronger hold over variables to obtain desired results.
- Subject or industry is not a criterion for experimental research due to which any industry can implement it for research purposes.
- Results are extremely specific.
- Once the results are analyzed, they can be applied to various other similar aspects.
- Cause and effect of a hypothesis can be derived so that researchers can analyze greater details.
- Experimental research can be used in association with other research methods.Experimental Research Study Essay
