Research Scenario A: Question 1: Step 1 selection of test statistics Null hypothesis The null hypothesis is a statement that explains there is no difference between two variables (Salkind, 2013). Using the research question, a
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.
The first method utilized by the
n research methods, every researcher uses a procedure or a means of measurement to collect data. For example, three types of basic measurement collection are self-reports, observational, and physiological. Each method has their pros and cons in research. Depending on the research you are conducting these methods of measurement can either guide you to great discovery the pro, or skew your data making it unreliable the con. Observational measure is the method of measuring behaviors by directly observing subjects (Leary, M. R. (2011).
a. Water boils to produce steam at 100 C (212 F) b. Water produces gas with sodium metal c. Water and oil separate when combined d. Water dissolves sugar 22. In the experiment, students put brine shrimp in water with different concentration of salt and counted the number. Which of the following changes to the experiment will increase confidence in the validity of the result? a. Count the number of dead brine shrimp instead of living brine shrimp b. Add more brine shrimp to the water with the highest salt concentration c.
Give details so I know you understand the type of research design. a. The research design that seems best fit would be an experimental
Within this essay, define evolution and also physical anthropology. Discuss some of the general ways physical anthropologists investigate evolution. Find at least one appropriate outside source that identifies one specific research project in which physical anthropologists are studying evolution. Describe the research project and its significance in our understanding of evolution. Choose and define a second subfield of anthropology (cultural anthropology, linguistic anthropology, or archaeology).
The scientific processes used in the three videos were all very similar besides the final information that was found. The first scientific process all of the videos have in common is collecting data. In the video”Ancient Farmers of the Amazon”, a graduate student named Cameron Currie, went into the forest to collect ant colonies to later examine. In the video “The Red Queen”, scientists from Rutgers University in New Jersey, go to a series of small ponds in a mexican desert, to later examine the reason why they reproduce differently. The last video “Tale of the Peacock”, Marion Petrie, who has a farm of birds in captivity, measured the tail lengths of a captive population of peacocks.
The methodologies consist of physicians that conducted a study or knowledgeable about the diseases, evidenced-based literature reviews, experiments, laboratory blood work, X-rays, drugs, and educational programs. Before the study began, the physicians had to persuade and consult the authorities to give them
The three different research methods are naturalistic observations, surveys, and case studies. A naturalistic observation is when someone is observing people or animals in a natural environment or set. A naturalistic observation would be good to use when you observing people in a a cafeteria. For example under appropriate conditions, you can observe the amount of people who naturally order healthy food verses unhealthy food. Naturalistic observation are good only if you take the time to observe people in their natural environments.

Scientific method: Scenario 1 Scenario assigned by instructor: _ an unexpected road block/detour while driving to work, school, etc Often, application of scientific methods gives persons an opportunity to conclude about causes of their problems in an expedient manner. However, to successfully solve a problem, an individual has to start by identifying the problem at hand which is then followed by evaluation of solutions using scientific methods. A scientific method works best when an in this scenario begins by asking myself why is there an unexpected roadblock on this route?
In a briefly describing the methods,
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.
