Advantages Of Niamh Taking A Survey Approach

An experiment could be devised in which bats are taken in a large quantity and one

Independent: The independent variable in the following experiment is the temperature as it is what is being changed and will impact the overall outcome of the experiment.

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.

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.

* Independent variable coefficient – This is the measured effect the independent variables have on the dependent variable. This is the main output of the regression analysis.

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.

Dependent variables are ones that change due to the independent variable. Independent variables are variables that can be manipulated or measured. This influences the dependent variables.

 Explain how the data collected will provide the data necessary to support or negate the hypothesis or proposition

Answer = A visual representation of the relationship between the independent and the dependant variables. Either bar or line graph.

There are a number of methods of collecting data, some of them are – questionnaire, surveys, checklists, interviews, observations, focus group etc (Cordray, 1986; Einhorn and Hogarth, 1986).

For me, I do not have enough knowledge about this project and there are so many topics that I do not have an enough in depth knowledge.And I am serious about the part of doing a questionnaire survey.

Psychological research may be undertaken on a subset of society; however the importance of the results may have an effect way beyond the group tested. The value of psychological research varies and the same results can be used in different ways by different groups of society.

The strength of questionnaires is it can give an insight into respondent’s thoughts and opinions and also cost efficient as it is inexpensive.

The null hypothesis suggests that there is no difference between the means of the three samples, while the claim in the alternative hypothesis suggests that at least one mean is different.
