The scientific method is a process for experimentation that is used to explore observations and answer questions. It allows psychological data to be replicated and confirmed in many instances, under different circumstances, and by a variety of researchers. (Lumen Learning). Scientists have different versions of the Scientific Method, here are the typical six parts: Purpose- What do you want to learn? Research- Find out as much as you can. Hypothesis- Try to predict the answer to the problem. Experiment- The fun part! Design a test or procedure to confirm or disprove your hypothesis. Analysis- Record what happened during the experiment. Also known as ‘data’. Conclusion- Review the data and check to see if your hypothesis was correct.

Dependent variable (the one that alters because of what we do), in this case reaction time. The dependent variable is usually the one we measure or record. The problem is always remembering which is which, simply to think of the dependent variable as the one that depends on what the researcher does! In this case reaction time (DV) depends on whether or not the participant has had a cup of coffee. Crucially an experiment allows researchers to establish a causal link between the IV and the DV. Following an experimental procedure, scientists should be certain that the alteration they have made in the IV has caused the change in the DV. Internal (or experimental) Validity Are the effects that have been caused due to the independent variable? For example, if researchers found that coffee (the I.V.) does increase speed of reaction (the D.V.), can researchers be certain that this increase is due to the coffee or could it be due to a confounding variable such as the time of day or just faster reactions of the second group. Common confounding variables include, the intelligence of participants, personality, gender, time of day, weather or the temperature. Because of these confounding variables in an experiment the researcher can take steps to minimise these, for example they could ensure that the procedure is carried out at the same time of day, in the same room, with similar temperature
Our dependant variable in this experiment was the dissolved oxygen parts per million in each sample. We recorded this data on the white board back in our classroom, writing down the specific parts per million that we found in the water. The variables that were the same for all
One is to “articulate the research problem and objectives”. Two is to “develop the overall research plan”. Three is to “collect the data or information”. Four is to “analyze the data or information”. Five is to “present or disseminate the findings”.
a biology class wants to perform an experiment to investigate the effect of different colors of light of green, yellow, red and clear cellophane and plant three seeds in each one. What part do the three seeds experiment? A,Confounding variables B.Independent variables C.Control variables D.Dependent variables 40. Iodine directly helps which of the following glands to function properly?
VARIABLES: There are independent variables, dependent variables, and controls. the one that is being tested and the one that is the inconsistent variable in the Independent variable like the volume and surface area of the agar cubes. The variable that is kept consistent is the dependent variable such as the percentage of diffusion of pigment in the agar cubes. The constant variable is the features of the experiment that is kept the same throughout the entire experiment such as, the amount of time the agar cubes are left in the beaker and the amount of acid in the beaker.
It’s a quantitative method that is specifically used in psychology researches and it examines whether two variables such as events, behaviuors, properties, and characteristics are casually related. In other words, it is a scientific and systematic approach to research, in which the researcher can manipulate and control the variables i,e an independent variable is manipulated and the dependent variable is measured and it could be called a true experiment. The main advantage of this method is that it allows us to determine and regulate cause and effect, and further it allows us to control the effects of extraneous variables. Experimental method involves some kind of measurement and a mathematical calculation is frequently involved.
Assignment: Explain how the scientific method works. The scientific method is fundamental to successful experimentation. It consists of four main stages: observation, hypothesis, experimentation, and analysis. A successful scientific endeavor covers each of these stages thoroughly.
They are all part of the second step in scientific method, designing and executing an experiment. Hypotheses come from theories. Theories are broader than hypotheses and may suggest many different hypotheses. The operational definition defines the variables in a hypothesis. 3.
The scientific method is a series of steps used by scientists everywhere around the world to work through data, hypotheses, observations and experiments. One of the most excellent examples of how scientists have used this to further progress in the human race is in the curious case of Legionnaires disease. The elusive disease first struck in 1976 at a convention in Philadelphia, causing an epidemic that would be researched for many months to come. Scientists finally came to a conclusion about the disease after following the scientific method with vigor. Understanding the problem in any situation is how you first approach solving it.
The definition of experiment is to try something to gain knowledge of the results or outcome of the experiment. Some of the ways that this has been used by Psychology were mention in the lesson such as the Monster study and different studies about attachments. I believe that dealing with the Experimental study the best term from the lecture would be the third perspective which is the cognitive perspective. The reason I chose this perspective is
In this experiment, the independent variable is turning the stairs into a piano, or making the stairs “fun” to passerby’s since it is being changed in the experiment. On the other hand, the dependent
The Scientific Method is when we take in information and observe what is going on so that we can test out our observations afterwards. We observe people so that we can find out their behavior. We test out our observations multiple times to make a theory. Scientific Method is related to the model because we observe how the patient’s anxiety levels change when gerbils and hamsters are used in waiting rooms.
Scientific methods provide limitations and boundaries that focus a study and organize its results. The scientific method involves developing and testing
There are 6 steps of the scientific method which are used in order to understand and answer a question. The first step of the scientific method asks a question you do this so you have a problem to solve because you can't just do an experiment while using the scientific method. The second step of the scientific method does background research you do this so you know more information about the question or problem you are trying to solve or answer. The third step is to construct a hypothesis this is when you make a guess of what the result will be. The fourth step is to test your hypothesis by doing an experiment this is when you can see the variables such as controlled, dependent, and independent variables.
The Scientific Method ties in with the ideas of rationalism and inductive reasoning. It indulges our desire to gain knowledge of ourselves and the world we live in. The Scientific Method was not developed by a scientist, but a philosopher named Francis Bacon. He believed that knowledge of nature should be gained through observation and reasoning. Clearing your
Scientists will create a hypothesis to condense what they expect to discover when investigating. One of the most critical steps in the scientific method is experimenting to test your hypothesis which sets up a person to review data and form a conclusion.
