STA630 Final Term Past Papers File 1 Subjective by Tanveer Online Academy

Question: Three advantages of Internet Surveys? Short

Answer: Following are the three advantages of internet surveys

•  Speed and Cost Effectiveness
•  Visual Appeal and Interactivity
•  Respondent Participation and Cooperation

Question: Why sample used rather than whole population? Short

Answer: Sampling is more practical and cost-effective than studying an entire population. It allows researchers to draw valid conclusions about the population by studying a smaller, representative subset, reducing time and resource requirements.

Question: What are major ethical dilemmas? Short

Answer: Following are the major ethical dilemmas:

•  Deception
•  Confidentiality
•  Involvement with deviants
•  The powerful
•  Publishing field reports

Question: Disadvantages of content analysis? Long

Answer: Following are the disadvantages of content analysis:

Bias: Documents used in research, such as autobiographies, may be biased because they are often written for profit, leading to exaggeration or fabrication. They tend to highlight positive aspects and omit negative ones.

Selective Survival: Common people's day-to-day documents, like letters and diaries, are often lost or inaccessible due to poor preservation. Famous people's documents are more likely to be preserved.

Incompleteness: Personal documents, not intended for research, assume prior knowledge and can be incomplete. Diaries, for instance, may contain more introspection than descriptions. Letters assume the reader's prior information. Lack of Availability: In addition to the bias, incompleteness, and selective survival of documents, there are many areas of study for which no documents are available. In many cases information simply was never recorded. In other cases, it was recorded, but the documents remain secret or classified, or have been destroyed.

Sampling Bias: One of the problems of bias occurs because persons of lower educational or income levels are less likely to be represented in the sampling frames. The problem of sampling bias by educational level is more acute for document study than for survey research. It is a safe generalization that a poorly educated people are much less likely than well educated people to write documents.

Question: Give suggestions for conducting interviews accurately? Long

Answer: Following are the suggestions for conducting interviews accurately

Prepare Thoroughly: Familiarize yourself with the research topic and relevant literature before the interview. Develop a well-structured interview guide or set of questions.

Establish Rapport: Create a comfortable and non-threatening environment to build trust with the interviewee. Begin with an introduction, explaining the purpose and confidentiality of the interview.

Active Listening: Pay close attention to the interviewee's responses, body language, and nonverbal cues. Avoid interrupting, and allow the interviewee to express themselves fully.

Open-Ended Questions: Use open-ended questions to encourage detailed and meaningful responses. Follow up on answers with probing questions to delve deeper into the topic.

Stay Neutral: Maintain a neutral and non-judgmental stance to avoid influencing the interviewee's responses. Avoid expressing personal opinions or biases.

Avoid Leading Questions: Frame questions in a way that does not lead the interviewee to a specific answer. Use neutral language to prevent bias.

Use Clarifying Questions: If the interviewee's response is unclear or ambiguous, ask follow-up questions to clarify their meaning.

Respect Silence: Allow for moments of silence to give the interviewee time to collect their thoughts and provide thoughtful responses. Record Accurately: Use a reliable recording device to capture the conversation accurately.

Ensure that all parties are aware of the recording and consent to it.

Take Notes: If recording is not feasible or as a backup, take detailed notes during the interview. Note key points, quotes, and important observations.

Question: Is it possible to use cause and effect relationship by using one shot case study design? Justification. Long

Answer: Using a one-shot case study design to establish cause-and-effect relationships is challenging due to its lack of control, temporal ambiguity, potential for alternative explanations, limited generalizability, and potential bias. This design can, however, be justified in preliminary exploration, when dealing with unique or uncommon events, when feasibility constraints are present, or for descriptive and exploratory research. While it may offer valuable insights, researchers should be aware of its limitations and consider complementary research methods for stronger causal inference.

In a one-shot case study, researchers observe a single group (or case) after exposure to an independent variable (the "treatment") and then measure the dependent variable to draw conclusions about causation. However, this design lacks a control group for comparison, making it difficult to attribute observed effects solely to the independent variable and rule out alternative explanations. Additionally, the absence of baseline measurements of the dependent variable complicates establishing a clear temporal sequence, a key criterion for demonstrating causation. While the one-shot case study can provide preliminary insights and be justified in certain contexts, researchers should exercise caution, acknowledge its limitations, and consider more robust research designs, when possible, to strengthen causal claims.

Question: Why unit of analysis is important during data collection explain with example?

Answer: The unit of analysis is critical in research as it defines what is being studied and profoundly shapes data collection, analysis, and interpretation. For example, in a study of educational performance, choosing individual students as the unit of analysis enables an in-depth exploration of factors affecting each student's performance, but it may not capture broader trends or systemic factors. On the other hand, if the unit of analysis is schools or educational districts (macro-level), the research may focus on the impact of policies, funding, or teacher qualifications, providing insights into larger-scale educational outcomes. Thus, the unit of analysis is pivotal in determining the scope, generalizability, and relevance of research findings
