The Scientific Method Paper
The scientific method Researchers use the scientific method as an approach to identify a problem, conjecture a hypothesis that could solve the problem, collect data pertaining to the hypothesis, and examine the data to determine if it supports or solves the research problem. The scientific method requires the use of deductive logic and inductive reasoning, and they fuel each other during the scientific research process. Deductive logic is important for creating research hypothesis and testing theories. It begins with a theory or argument, and researchers gather data to test the theory (Levy, 2013). Inductive reasoning is when researchers draw conclusion about a large population from observations on a smaller sample of the population. This …show more content…
Rather, they choose a subset or sample of the people they are interested in studying. The conclusions drawn from the sample testing can be used to make generalizations about the entire populace if the sample is an accurate representation of the population. This refers to the research’s external validity. It is very important the researcher accurately writes in the study that he is using a sample or subset of a population. Cautious researchers say exactly what their intent is (Leedy & Ormrod, 2016). Some of the many types of sampling procedures are simple random sampling, stratified random sampling, convenience sampling, and snowball sampling. I prefer the simple random sampling procedure. Randomization ensures that the comparison groups are equal with respect to how they occur in the population (Morrison-Beedy & Melnyk, 2012). It is not practical for sampling large populations, but is effective for research done on small populations with known individuals (Leedy & Ormrod, …show more content…
Qualitative research is exploratory, and researchers use this to investigate a topic that is immature. An immature topic is when the variables are unknown and little research has been done. Other reasons to use qualitative research is when the available theory on the topic is incorrect, inappropriate or biased. It is also a good method to use when a need exists to explore and describe the topic and to develop a theory. This approach is also necessary when the nature of the topic or situation does not fit with the quantitative approach to research (Creswell, 2014). The most commonly used methods in qualitative research are participant observation, interviews, and focus groups (Leedy & Ormrod,

The Scientific Method In The Hot Zone By Richard Preston
568 Words | 3 PagesThe Scientific Method is a way to answer and ask scientific questions by creating a hypothesis and creating an experiment. The steps of the scientific method include: asking a question, background research, creating a hypothesis, test your hypothesis by doing an experiment, analyzing the data, drawing a conclusion, and finally publishing your results. There are many places in the book The Hot Zone by Richard Preston in which steps of the scientific method are used, the first one I found was during the Kitum Cave expedition. In the Kitum Cave expedition, Eugene Johnson set up an experiment to test if the source of the virus that infected Peter Cardinal and Charles Monet was inside Kitum Cave.
Write A Rhetorical Analysis Of The Scientific Method By John Barry
581 Words | 3 PagesScientific research is methodical. Created from a desire to make the unknown known, the “scientific method” was created in the 15th century based on common sense. As Barry analysis the scientific process, he says that the unknown must be made into a tool, even against one’s own ideas and beliefs. However, that concept is tenuous, so Barry uses logical situations to present the idea.

1137 Words | 5 PagesThis is called the scientific method and has been used not only in fields of science but also in politics and government. Document three is a model of the scientific method from 1999. The model consists of the 7 steps of this process. One: state the problem, two: collect information, three: form a hypothesis, four: experiment, five: record and analyze data, six: state a conclusion, seven: repeat the steps. The method was built using logic and reason to get from one step to the next.

So participants are selected on the bases of study’s purpose. The sample should comprise of the individuals who meet the category or criteria being set for the research objectives. For example researcher investing a cosmetic product which is designed only for the females between 50-60. The researcher does size up the individuals passing by who seems to meet that criteria or be in that category (only females between 50-60).
Scientific Method Steps
506 Words | 3 PagesThe scientific method is defined as procedures to pursuit knowledge while recognizing the formulation of a problem. This method contains six different steps to obtain a theory. Step one make an observations, step two form a question, step three form a hypothesis, step four conduct an experiment, step five analyze data, and finally step six is conclusion. These steps are documented very well so that other scientists researching the same field can refer back to the documentation. Making an observation or asking a question is step one in the scientific method.

824 Words | 4 PagesThe participants selected and the methods of selection will ultimately define the boundaries of the study results. Judging the external validity of a study (i.e.: Assessing to whom the study results may be applied) requires that a comprehensive description of the selection standards and selection methods and descriptive data regarding the study sample be provided. This subsection could begin with a brief introduction of the study setting, in order to contextualize the work showed. This should include the setting, location(s) and relevant dates of the study, indicating, for example, periods of recruitment, exposures or interventions, follow-up and data collection. After introduction of the work setting, there are three major issues that should
Sampling Frame For A Research Study
1174 Words | 5 PagesDetermining of the sample size is a crucial issue as the samples which are large can waste time, money and resources. Conversely, the examples that are very small can lead to inaccurate outcomes (Button et al., 2013). The sample size of the targeted population determines how well the targeted population gets represented. One of the merits of systematic sampling method is that the routine samples are easy to construct, compare, execute and understand. The process greatly helps my research study since it operates on a tight budget.

Qualitative research is a research method that is “conducted in a natural setting that seeks to understand a complex human behavior by developing a complete narrative description of that behavior” (Smith & Davis, 2013, pg. 52). Examples of qualitative research includes: naturalistic observation, ethnographic inquiry, participant observation, focus groups, narrative studies, case studies and artifacts
Scientific Method Steps
212 Words | 1 PagesThere 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.

Two ways to do this are inductive reasoning and deductive reasoning. In the following paragraphs, inductive and deductive reasoning will be compared and contrasted, as well as analyzing which would be best to use to establish cause and effect. First, how are inductive and deductive reasoning the same? In both inductive and deductive reasoning, a form of logic is used.
Three Types Of Research Methodology
700 Words | 3 PagesQualitative research method has been widely used to gather data on specific subjects. With in- depth analysis, this method helps the researcher to get greater insights on various phenomena. The major reason why it is usually preferred over other methods is that it not only examines the when, where and what of a decision making process but also the why and how. Debates, interviews and various other researches are the areas where this approach is commonly used. Depending on the requirement of the research, the data gets streamlined once the entire data is obtained and gathered.
