Question One

Steps of the ethical review and procedure

Determination of project ethical review requirement- At this step it describes that before starting of a research on the project, it requires approval from the Research Ethics Board. Impacts of Facebook on reality friendship project involves humans subject that requires approval from the research ethics board

Determination of which research board should review the project- This describes that on starting the project appropriate research board must approve the project. On the impact of Facebook on reality friendship project is appropriately reviewed by the Behavioral research ethics board.

Step three

Assessment of the level of risk of the project- This step describes that the risk of harm anticipated in the proposed project should be minimal or have smaller magnitude in the society.

Step four

Submission of ethics application form to ethics office- This describes that graduate submitting their research proposal for ethical review need to prepare the submissions as per the requirements of procedures and forms of appropriate ethics board.

Revisions suggested by the Research Ethics Board should be implemented- According to this step; researcher is required to modify the project as required by the Ethics office.

Receiving the Boards certificate of approval and begins the project- This is the last step that researcher research proposal meets the requirement of Research Ethics Boards and thus a consent of certification of beginning the project is granted.

Question two

Importance of each of the six steps of hypothesis testing in a mixed methods research project.

The six steps of hypothesis testing includes

  1. Stating hypotheses of the interest

  2. Determination of appropriate test statistic

  3. Specification of level of statistical significance

  4. Determination of decision rule on whether to reject or not the null hypothesis

  5. Collecting the data and performing the calculations required

  6. Deciding on whether to reject or accept the null hypothesis


  1. It provide a systematic paradigm of collecting and analyzing data in mixed research projects

  2. It provides sequential integrations of data based on the stated hypothesis.

  3. Its gives priority on forms of data with higher significance hence providing appropriate decision rule

  4. It defines procedures on the appropriate statistical inference to obtain a quality decision criteria based on research project.

  5. It specifies calculation framework and these procedures of obtaining quality decision precedent.

Question 3

Null Hypothesis

Null hypothesis refers to a statistical inference that accentuates the dissimilarity of the relationship between two measured research occurrences. The null hypothesis describes the hypothesis where the data pattern set up has occurred minimally by chance. It also assumes to be factual until statistical evidence nullifies it for a substitute hypothesis, it also assumes
that any kind of variant or impact on a set of data is due to chance. Null hypothesis is applied in evaluating the reliability of a hypothesis about a phenomenon the is relied in making an judgment on the research projects.

Confidence Interval

Confidence interval (CI) refers to a statistical technique that is used to measure the reliability of the approximation population parameter. The confidence interval is calculated majorly using the observations in account of different sample size. It is applied in determining the viability of research data between quantitative and qualitative research methods.

Test Statistics

Test statistic refers to an ideal single measure features of a sample used in statistical hypothesis testing. This test is normally specified in terms of a test statistic and considered to be arithmetical summary describing the data-set that condense the data to one value utilizing when performing hypothesis test. Generally, test statistic is clearly applied in quantifying research data in distinguishing the alternative hypothesis against null hypothesis.

Question 4

Pursing of research question is done through both qualitative research that includes interview, and quantitative research including questionnaires. This are describe as follows,

Qualitative research

Qualitative research refers to a methodical exploration of social phenomena through narrowed down formulated questions to describe and understands ideas, beliefs and values. The examples of qualitative research are interviews and observation.


Interviews refer to a methodical approach used to obtain facts trough face to face discussion with human subjects. This qualitative research approach will provide primary data such values ideas and believes of the interviewed persons. This research method is considered in obtaining accurate data but also it is time consuming and the use of interviews tend to distract contender personal activities.

Quantitative research methods:

Quantitative research defines procedural approach that aid in fitting research trough responses on the selected sample opinion that are analyzed statistically. Quantitative research method includes questionnaires.


Questionnaires are research tools that consist of logical and easy series of questions that is used in assembling information from respondent through statistical approaches. Questionnaire provides designed primary data about the norms of respondent since they receive immediate reaction from respondent. The use of questionnaires is actually difficult to design since the structure of questions determines the responses. This method is advantageous since the use of questionnaires minimizes the cost involves in the study as compared to the interviews.
