Research Methods Assignment
1. The 8 steps of a psychological research.
a) Identifying the area and aim of research
- In this steps you are required to find out the area of research you will undertake and what the research will achieve.
b) Gather information
- Gather all necessary information about the area of research.
c) Identify research question and Formulate hypothesis
- Ask questions about what the research is trying to depict and form a hypothesis about what you assumptions are.
d) Design a method to test the hypothesis
- Create a method/experiment that will test if the hypothesis is either correct or incorrect.
e) Collect and analyses the idea
- Gather the result of experiments and examine the results.
f) Draw conclusion about if the result approves of the hypothesis
- Conclude and articulate whether the hypothesis was approved by the result.
g) Report result
- Report the result as a scientific research.
h) Test the conclusion
- Test this same idea using the same method in different areas (different samples).
2. Independent (IV) and Dependent variables (DV) are the two features that best differentiate between an experiment and other research methods as they test the relationship of the cause and effect.
3. See last page for Glossary*
4. The term cause-effect refers to the relationship between the IV (cause) and DV (effect). Since the DV depends the characteristics of IV, the IV can be manipulated and designed to specifically alter the value of DV to test a certain idea or hypothesis.
5. Identifying IV and DV
a. IV = receiving the reward. DV= increase of time spent by students while studying.
b. IV = people being in love. DV = more positive perception of eac...

...al condition The procedure that is manipulated in order to estimate the effect of a variable with a comparison to a controlled condition.
Exposure to IV is considered an experimental condition.
Control condition A normal condition of experiment from which other scientific experiment with different conditions are compared.
Experimental group An experiment carried out to test a hypothesis, providing an insight to the relationship between the IV and DV.

Identify the hypothesis (testable question) that the study was trying to answer and describe the methods of research used in each study.
Going into details of the article, I realized that the necessary information needed to evaluate the experimental procedures were not included. However, when conducting an experiment, the independent and dependent variable are to be studied before giving a final conclusion.
Experimental research is the one type of research that allows psychologists to make causal statements. It is where the researcher changes one or more variables that may have an effect on some other variables (King, 2016). The hypothesis is a specific expectation about what is going to happen in the experiment (King, 2016). In the research, the hypothesis was that women would perceive fat talk to be more socially acceptable than men (Katrevich et al., 2014). The other elements of experimental method are dependent and independent variables. The independent variable (IV) is the cause of the results, and it is changed by the experimenter to find the effects, but the dependent vari...

Unlike a random experiment, a natural experiment is mostly observing what has occurred. What's more, a natural experiment gives researchers limited control over a study. Like a random experiment, variables are separated and compared to determine the effect of an independent variable on a dependent variable. At any rate, Dr. Dee selected to go with a natural experiment on the grounds that a random experiment was not a viable option. In particular, Dr. Dee's natural experiment focused on the results of a 1988 National Education Longitudinal Survey of 8th grade teachers. Specifically Dr. Dee examined the effect that a teacher's gender had on student test scores. Dr. Dee takes this a step further by considering the size of a classroom, the race of a teacher, years of experience a teacher has, and whether a teacher was certified in their subject of teaching. It is important to remember that Dr.Dee uses the results of one year and does not take into consideration following years. Beyond this, Dr. Dee also examines student perception about the four core subjects. In short, Thomas Dee examined and manipulated what had occurred to come to his
Do you think its fair that players are credited for what they do, when cheating the game? Mark McGwire excelled at the game of baseball and got credit for all of his accomplishments, yet he cheated the game and used steroids. Babe Ruth, considered one of the greatest baseball players to play the game of baseball, who never cheated and set a great example for all who play baseball. Baseball has drastically changed over the years, especially in the cheating scandals of steroids; Babe Ruth set a great example by excelling in the sport and doing it clean, contrasting with Mark McGwire. Their existence shows how society accepted honesty and doing it the clean way in Babe’s era and how society accepts the scandals and dishonesty of Mark’s era.
The information gained may support or yield opposite results based on predictions being tested. My independent variable would be time and the dependent one would be the enzyme pectinase. I believe the key feature of my experimentation is the control of most factors so that the influence of a single factor can be seen clearly.
The research question is the first and foremost initial step in the research process, because it defines the expected outcomes and drives the project design. So it should be clear and concise once the research question is formulated, the next is defining the terms and concepts used in the research process. A literature review is needed to clarify issues, gives an understanding to the researcher how others have formulated similar research questions and defines concepts.
The study is usually described as an experiment with the independent variable being, the condition the participants are ...
The first method to be discussed and analysed are experimental methods. There is a variety of experimental methods including; laboratory, field and natural experiments. These methods are the most scientific method due to them being highly objective and systematic. In addition, this method is regarded as the most powerful research method used in psychology because of the potential to investigate the causes of events and therefore, identifying the cause and effect relationship. When carrying out an experiment the researcher intervenes directly in the situation being investigated. The researcher manipulates an independent variable (IV) in order to investigate whether there is a change in the dependent variable (DV). Any other variables that could have an
A researcher uses an experiment to scientifically test out a hypothesis. In an experiment there are many different factors that are involved. There is the independent variable, which is the cause, it is the one that is being manipulated, and the dependent variable, which is the effect, is the response. When conducting a experiment it is important to make sure that the only thing than can affect the dependent variable is the independent variable. This is known as internal validity. Using random assignment to separate the participants into groups helps eliminate any outside factors, and creates an equal chance for all participants to be apart of the experimental conditions. There are many pros and cons to this type of method. The experimental method creates a strong control of the variables involved in the experiment, which allows an easier determination on cause and effect. If needed, it is fairly easy to replicate an experiment and is less time consuming than other research methods. However there are many downfalls as well. When conducting an experiment the setting of where the experiment is taking place is more artificial which may cause certain behaviors that wouldn’t occur in real life. This is known as external validity, which is the measure of how much the results of a study can be generalized and used in different situations, and people. To improve external validity cover stories are created when conducting experiments so the participants are not aware of what is really going on, or experiments are done in a natural setting as opposed to in a laboratory. However, this creates less control over confounding variables that can affect the experiment, which can create bias results (Aronson,
... tested in the same manner for a specified purpose in order to maintain consistency and validity within results.
The measure of the dependent variable is a significant element in experimental and quasi-experimental designs and allows for comparison of groups. Both designs can show probability of cause and effect relationships, which is important in research (Writing @ CSU, 2010).
After establishing the research problem and what results are wanted, it will define how it will find the answers. Research is a form of collection and interpretation of information that will form the basis of finding answers to questions. The research uses theories and methods that h...
Research which is also known as the search for knowledge is an art of scientific search for specific information. According to Clifford Woody, the research includes defining and redefining problems, formulating hypothesis and suggested solutions, collecting, organising and evaluating data, making deductions and reaching conclusion and further testing whether the conclusion will fit into formulating hypothesis. Research Methodology is a scientific and systematic way of finding solution to a problem. In this research, researcher has studied various steps for research like problem along with the logic behind them. For this study, researcher must know various research techniques like mean, mode,
