After deciding that MMR is suitable for the study, the researchers determine their rationale for using a mixed design. Participant enrichment involves blending quantitative and qualitative research to better the sample using approaches that encompass recruiting participants, dealing with activities such as institutional review board interviews assuring that each participant chosen is eligible for involvement. Triangulation seeks convergence, correspondence, and corroboration of results from different methods studying the same phenomenon. Instrument fidelity pertains to evaluating the convenience and/or effectuality of current instruments, by generating new instruments and observing performance of human instruments. Significance enhancement refers to interpretation and utility of findings.

Census is data collected from every member in the society by governments for official purposes and could vary from general demographic information such as sex, age, education, place of birth to questions about households. If the entire population is surveyed, meaning it is a census representing 100% the population.

Anonymity and confidentiality are the two strategies used to maintain/protect privacy. For example, there are several ways to secure the anonymity of personal information (i.e., research data). “The most obvious one is to replace actual names with invented ones [i.e., pseudonyms]. Another is to refer to people solely by the roles that they play: doctor, nurse, patient, relative, and so on. Alternatively, first names without second names, or just initials, may be used; or numbers or letters of the alphabet: Informant 1, Informant 2; Doctor A, Doctor B, etc. The correct answer is E. 

Regression analysis is a method used in quantitative analysis when carrying out complex statistical tests. The correct answer is D. 

Significance enhancement refers to interpretation and utility of findings.

A,B,C and D are the four principles of principle-based ethics. However, scientific validity stands to look at whether the proposed research is methodologically rigorous and it is one of the seven requirements Emanuel, Wendler and Christine (2000, pp. 2703- 2707) proposed as a coherent framework for making research ethical. Therefore, the correct answer is E.

There is a significant difference between the natural sciences and the social sciences.

C

Self-reflexivity is a representation of the researcher’s voice (i.e., the influence of the researcher’s values and assumptions on the process of inquiry). The correct answer is C. 

d

Parallel sampling: Sample for the quantitative and qualitative components of the study are different but are drawn from the same population of interest.

Conversion: The extent to which the quantitizing or qualitizing yields quality meta-inferences

Research instruments are the tools and approaches used to collect data to answer the research question / hypothesis. More than one technique can be employed, the commonest are questionnaires and interviews. Research instruments or measures are the source of the actual data. These can be surveys, interviews, observation and measurement of demographic characteristics (gender, age, height, weight etc.) of the participants. Describing the measure is important because measures are the source of your data. All the results rest on whether or not the measures are adequate, whether measures help the reader judge the validity of the results or not.

Quantitative research, or also called scientific research method, is a way of obtaining information that provides the researcher with accurate and reliable data that is numeric in nature and has been obtained through testing or comparing ideas in the public arena.

The national time series surveys generally are data collected over the years that are in the interest of political scientists. Indicators may vary from economic to social indicators, such as income levels, education level, employment or unemployment figures by education level, in or out migration trends within a nation.

-Questionnaires can be seen in three categories. The first is the closed ended or structured ones, the second is open ended or unstructured ones, and the last is a mixture of closed ended and openended questionnaires. 

-Actually it can be said that closed ended questionnaires give the researcher
quantitative or numerical data and open-ended ones give qualitative or text information.

-To exemplify, when a participant of study is distant, the researcher may send the questionnaire by post. But the return rate of them become quite low.
Moreover, they can be delivered online. In this process, the rate of return may be slightly higher as it is easier for respondents to reply.

-Experimental designs provide the researcher with the opportunity to determine the independent variable’s effect.

-The researcher should assign the participants in each group randomly. Subjects cannot decide which group they are going to be in.

-Classical experimental design employs randomization to assign participants to
groups whereas quasi-experimental design makes use of non-randomized procedures.
