TRIBHUVAN UNIVERSITY

2080 Bachelor Level (4 Yrs.)/Science & Tech./ III Year

Research Methodology [R.M.305] (Compulsory)

Time: 3 hrs.

Full Marks: 100

New Course

Candidates are required to give their answers in their own words as far as practicable. The questions are of equal value.

10x10=100

Attempt any TEN questions.

  1. Define research. Explain the chief characteristics of scientific research.

  2. Define research problem. Explain the ways of selecting a meaningful research problem. Also, describe the methods of problem identification.

  3. What are the methods of data collection for the purpose of research? Discuss the ways of data collection activity by schedule. Also, describe different types of schedules.

  4. What is sampling? Discuss the needs of sampling for research work. A statistics practitioner would like to estimate a population mean within 15 units. The confidence level has been set at 99% and population standard deviation = 174. Determine the sample size.

  5. What are the methods of reducing the non-response rate? Discuss the methods of the random response technique with an example.

  6. Differentiate between descriptive and inferential statistics. Define the term standard error.

  7. Define the terms 'reliability' and 'validity.' A test is supplied to a population of large size. The mean score is obtained as 75 with a standard deviation of 12. The reliability coefficient of the test is found to be 0.9. If an individual X obtains a score of 60, what is his true score? Also, estimate the 95% confidence interval of the true score.

  8. What is a score? How can a score be transformed into a percentile score? In a test, six individuals A, B, C, D, E, and F scored the ranks 5, 2, 1, 6, 3, and 4 respectively. Find the percentile ranks of 'B' and 'E'.

  9. What is a case study and how does this method help in research work? Explain.

  10. What is a research report? Explain the various steps required to follow in the preparation of a final research report.

  11. What do you understand by 'Review of literature'? Discuss the importance of literature review in research.

  12. What is a thesis? Discuss the steps in thesis writing. Compose a format for the documentation of the topics in a thesis. 


Old Course

Full Marks: 80

Attempt any EIGHT questions.

8x10=80

  1. What does research mean? Explain why research is regarded as a scientific activity. Mention the chief characteristics of scientific research.

  2. What do you understand by 'Review of literature'? What purpose does it fulfill in research work?

  3. What is a case study? What are its types? Explain the steps to be adopted for a complete case study.

  4. What is a schedule? What are its purposes? Point out the different types of schedules.

  5. Define sampling and explain the characteristics of a good sample. A large manufacturing firm wishes to estimate the mean weight of 5000 packages of raw material. A simple random sample of 200 packages yields a mean of 36 kg. The population standard deviation is 3.4 kg. Construct a 95% confidence interval estimate of the true population mean.

  6. Define the terms "reliability" and "validity." A test has a reliability coefficient of 0.70. The test scores have a correlation coefficient of 0.85 with criterion 'C'. What will be the validity of the test criterion if the length of the test is doubled?

  7. What is a research proposal and what are the major steps involved in preparing a research proposal?

  8. What is a thesis? Discuss the steps in thesis writing. Provide a format for the documentation of the topics in a thesis.

  9. Define and discuss different kinds of research reports. Describe the qualities of a good research report.

  10. Write about reference citing. Discuss different approaches used in quoting 'Journals,' 'Books,' and 'Articles.'

5 Major Differences between Homeostasis and Hemostasis

Certainly! Here's the updated table with disorders that can affect homeostasis and hemostasis: ```html Homeostasis vs Hemostasis Homeostasis vs Hemostasis Aspect Homeostasis Hemostasis Definition and Purpose The body's ability to maintain a stable internal environment despite external changes. Involves balancing temperature, pH, electrolyte levels, etc. to support cellular function and organ health. The process of controlling bleeding or stopping blood flow after an injury. Involves vasoconstriction, platelet aggregation, and blood clotting to prevent excessive blood loss and promote wound healing. Scope and Applicability Applies to the entire body. Aims to maintain overall internal balance and stability. Specific to the circulatory system. Activated only in response to vascular injury or trauma. Regulation Mechanisms Primarily regulated by the nervou...
