Provide 4 answers. Tell me why the correct answer is correct and why the incorrect answers are incorrect. 1. This occurs when a researcher fails to reject a null hypothesis that is
The scientific method includes the following steps: asking a question, do research, make a hypothesis, test your hypothesis by doing an experiment, analyze your data, draw a conclusion, and share your results. In this book, many scientists are mentioned. Some of the scientists mentioned are doing experiments on Henrietta’s cells. For example, George Gey and William Scherer did an experiment on Henrietta’s cells to test how they reacted to the polio virus (Skloot, Location 1553). They, like all other scientists, used the scientific method in order to do this.
Last but not least, science is characterized by its incessant evolution in a way that a single new anomaly can easily falsify a strong scientific theory. In simple English, even experts know that there is no ultimate certainty to
The third assumption being that natural events are caused by a natural phenomenon, you cannot just blame God or luck for things happening, and the last assumption stating that the simplest explanation that can explain the data is the best explanation to go with. While these assumptions are where scientists begin
The most public way are those that are medical in nature. For medical science has an impact on human health and life in different ways. Although, most medical experimentation is carried out using laboratory
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.
The first method is critical thinking, which carries about six steps, it starts from central issues and follows steps by finding evidence, evaluating, then lastly finding what data is supported toward solving the case. The next method is the scientific method, which means solving a case is like doing science project where you have a problem, hypothesis, and data. Then you interpret the data, if it proves your hypothesis or not, then support it with data, and lastly is conclusion, which is putting your findings together. The last method is criminal investigation, which is more focused towards crime, like what crime was committed and then how. Then if there's any suspicion toward any suspect they look for evidence; physical evidence, interviews, and the crime scene.
Moreover, when studying natural phenomena, physicists have two main methods for producing scientific knowledge: the scientific method, in which the physicists
2. Evolution- Until nineteenth century, many religious people believed
Sir Francis Bacon first introduced the scientific method in 1561 (Ullmer, 2011). Bacon said that his new method could produce much knowledge by observation and/or experience. The scientific method allows us to accept skepticism and use critical thinking for obvious explanations and to use experiments to make sure we test an alternative hypothesis (Blanchard, 1958). In 1879, Wilhelm Wundt founded the first psychological laboratory in Leipzig Germany (Blumenthal, 1975), where he used the scientific method by using objective measurement and control to analyze how the mind works (McLeod, 2008). Psychology allows one to explore how a person acts, feels, and thinks (Albee, 2002).
Methods of inquiry is part of the Scientific Method and can help to reconstruct the past as well as bring up some good questions in order to find answers. The Scientific Method is a prestigious set of methods that can be helpful in order to begin a crime scene as well as be a part of the reconstruction phase that would be going on. As we look at the methods within the Scientific Method we can see we have, hypothesis, theory, analysis, classification, inductive and deductive reasoning. This helps bring insight into being able to divide methods into two different categories; those that reconstruct the past and those that discover or create new knowledge. One method consists of historian, archeologist, epidemiologist, journalist and criminal
It builds upon preceding information, uses all of the facts obtainable to come up with a suitable hypothesis. It is reliable as it examines the testability of a theory and guarantees that the premises provide support for the conclusions. For example, the first observation Isaac Newton made before discovering the Law of Universal Gravitation was the apple that fell from a tree. His insight was that the force of gravity might not reach the orbit of the Moon if the force of gravity hits the top of the highest tree. He conducted a thought experiment which shows that as we fire a cannon from a mountain, the gravitational force directed toward the center of the Earth and the acceleration will cause the projectile to fall to earth as suggested by the shortest trajectory.
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.
A number of basic standards for determining a body of knowledge, methodology, or practice are widely agreed upon by scientists. One of the basic notion is that all experimental results should be reproducible, and able to be verified by other individuals.[13] This standard aim to ensure experiments can be measurably reproduced under the same conditions, allowing further investigation to characterize whether a hypothesis or theory related to given phenomena is valid and reliable. Philosopher Karl Popper (?) in one of his project attempted to draw the line between science and pseudo-science.
Knowledge we ascertain influences technological innovations we use today. It also mentioned the steps and guidelines we must follow to be effective and accurate when using he Scientific Method. The first step on doing so is to define the problem. You have to develop a concept you want to study. It is important for you to be specific with what you want to research on, as it is your basis and goal of your research.
