Research questions are formulated in a study to inquire about variables, both independent and dependent variables, and the relationship between them. Research questions are categorized into two, that is, qualitative and quantitative research questions. Qualitative questions are used in qualitative research like case studies, surveys and action research where the approach is non-numerical and analyses special phenomena that occur in nature. Quantitative research on the other hand is more of a systematic approach with measurable numerical quantities that go through analysis to prove a hypothesis. Finally, the research hypothesis is either approved or disapproved with regards to the results of the analysis (Laureate Online Education B.V. …show more content…
It must be logical, and provide a concrete base for any differences between the variables. It must also be simple and clear.
A hypothesis can state the following: there exists a positive relationship between employee performance and flexible working hours. Whereas a research question could generally be: do flexible working hours affect workers productivity? You can clearly see that the hypothesis states clearly and it is more specific in its prediction unlike the research question (eNotes.com, Inc 2011).
Hypothesis is typically used in quantitative research only. Moreover, when a question poses an inquiry on the relationship between two variables, a hypothesis is a statement declarative in nature of the relationship between different variables (Pajares 2007). A researcher chooses whether to use a question or a hypothesis depending on the purpose of the research, its objectives, the methodology for the research and the preference of the audience to receive the research. A researcher must be able to interpret the final outcome with reference to the research questions or the hypothesis used (Pajares 2007). A research requires a minimum of two hypotheses namely a null and an alternative hypothesis.
So, somebody can make a certain observation and come up with a hypothesis about how and why a phenomenon occurs the way it is. Hypothesis could be
Frame a research question/state a hypothesis as to what you will be looking to demonstrate in your work.
Select one (1) project from your working or educational environment that you would use the hypothesis test technique. Next, propose the hypothesis structure (e.g., the null hypothesis, data collection process, confidence interval, test statistics, reject or not reject the decision, etc.) for the business process of the selected project. Provide a rationale for your response.
For the following research questions, create one null hypothesis, one directional research hypothesis, and one non-directional research hypothesis.
In an experimental research, the use of a research question answers the thesis statement that enables one to research about a problem (Yin, 2013). From the experiment, the research question can be clearly stated as “which vaccine is more effective for preventing getting the flu”. In this case, the problem being researched about is the flu the possible solutions to this problem which the use of vaccines is being analyzed. The null hypothesis of this experiment states that there is no effective vaccine for preventing getting the flu while the alternative hypothesis states that there is an effective vaccine for preventing getting the flu.
A hypothesis is an explanation that can be tested based on observation. A statistical hypothesis is testable explanation based on observation and different variables. A null hypothesis explains what the results of the experiment will be if the original hypothesis is wrong. An alternate hypothesis is the opposite result if there is or isn’t a null hypothesis. Semmelweis hypothesized that bacteria/virus filled extremities resulted in higher death rates.
~ From the example above, the dependant variable is banana quality and the independent variable is time
The researchers included both a hypothesis and research questions. They stated a hypothesis, however it is a research hypothesis versus a null hypothesis. A research hypothesis explains there is correlation between two or more variables. A null hypothesis is a classification of hypotheses that states there is no connection between the independent and dependent variables. Statistical testing is performed to determine whether the statement is acceptable or not. Whereas the research question is an analysis statement detailing the variables and population of the specified research study (Adams, 2015). The hypothesis, the authors were hoping to prove, was whether the use of music would reduce pain and anxiety in postoperative pain in a particular patient population during a defined time frame (Allred et al., 2010). An example of a null hypothesis for this study would state music would have no effect on postoperative pain in a particular patient population during a defined time frame. There were four research questions the researchers attempted to answer. Three of the four questioned the effect of music on the patient’s pain, anxiety, and physiologic parameters. However the fourth question pertained to the impact of music on the amount of opioids taken from the beginning of the intervention until six hours later (Allred et al., 2010). The clinicians had not mentioned this component of the study before
When discussing the research question and hypothesis, one might interrelate these two concepts when in fact these terms differ from one another. The research question guides the research by creating a question that pertains to a particular topic one might be interested in gaining more knowledge in that particular area (L. Sabol, personal communication, April, 2016). Research questions can come from values, theories, or previous research (L. Sabol, personal communication, April, 2016). The research question within the article that the researcher wanted to examine is, “To what extent do pre-college characteristics and the academic performance of Black male student-athletes differ from their student-athlete peers?”(Horton, 2015, p. 289). With this research question the author Horton (2015), is attempting to figure out whether there is a relationship between Black male college student
The research question and hypothesis are extremely important to conduct any type of research study. The research question presents the idea that is to be examined in the study and is the foundation of the research study. Where, hypothesis attempts to answer the research question. The hypothesis is a prediction of what the study will find (Wood & Haber, 2014). The research question being studied in this quantitative study is “ Does tobacco cessation program has an impact on veterans with substance use disorder (SUDs) in reducing the use of tobacco, alcohol, and other drugs?” The researcher is trying to evaluate the impact of the tobacco cessation program on veterans seeking treatment with the substance abuse disorder (SUDs). The hypothesis being studied is “The tobacco cessation program will have a positive impact on veterans with SUDs in reducing the use of tobacco, alcohol, and other drugs”. According to the article, the tobacco cessation program does have a positive impact on veterans with SUDs. At 1-month follow-up, 88 participants out of 97 reported abstinence from alcohol, 89 reported abstinence from other drugs and 14 reported abstinence from tobacco (Vest, Kane, DeMarce, Barbero, Harmon, Hawley, & Lehmann, 2014).
Step 1: During this step of hypothesis testing, the query is stated again as a research theory and a null theory regarding the populations. The null and research hypothesizes are the opposites of each other. This step is necessary because it explains the theory and recognizes the populations, which will be worked throughout the study.
2. Explain the difference between quantitative and qualitative research questions. What is the scientific objective of each type of question? How is each related to deductive and inductive inquiry?
There is also a lack of direction in the hypothesis that aims to explore the positive or negative correlation of the independent or dependent variable. Furthermore, the hypothesis is a factual statement that can be immediately verified after a quick search on the Internet.
The researcher will answer the said questions in the light of theoretical and practical reason. The researcher will conduct simply survey to be able to arrive at the proper conclusion.
Research methodology is a way how the research is conducted step by step and in order. There are two methods used for data collection which is the primary data and secondary data. These data can be obtained and used many ways. The data is taken and analyzed in advance to produce a result that we can use for research and future reference. This study will relate to the objective we want to achieve and finding the answer to every objective we seek. In order to successfully achieve the objectives we seek, we must know
Formulating a research question is one of the most important aspects of research itself. There are two
