Ans: Research is a systematic and organized process of inquiry aimed at discovering, interpreting, and expanding knowledge through the collection and analysis of information.

(b) Which type of Method is more effective when the size of the population is large?
Ans: A sampling method, particularly a representative and randomized one, is more effective when the size of the population is large.
(c) Collection of information through continuous watching and noting down information in the natural setting of the respondents is observational  method of data collection.

(d) What is Inductive Method?
Ans; The inductive method is an approach to reasoning in which general principles are derived from specific observations or cases, moving from the specific to the general.
(e) What is Reliability ?
Ans:Reliability refers to the consistency and dependability of research results, indicating the extent to which a measurement or test produces consistent and stable outcomes over time and across different conditions.
(f) What is the full form of ‘PRA’ technique of data collection?
Ans: The full form of ‘PRA’ is Participatory Rural Appraisal, a technique of data collection that involves collaborative and inclusive approaches, especially in rural development contexts.
(g) What do you mean by Primary source?
Ans: A primary source is an original, firsthand, or direct piece of evidence or information created at the time under study, providing direct insight into a particular event, phenomenon, or subject, often in its unaltered, original form.
(h) What is Participant Observation?
Ans: Participant observation is a qualitative research method where the researcher engages actively in the activities of the group being studied, observing and sometimes participating in their daily lives to gain a deep understanding of their culture, behavior, and social dynamics.
(i)What is the main purpose of Literature Review?

Ans: The main purpose of a literature review is to provide a comprehensive overview and synthesis of existing research and scholarly works on a particular topic, helping to identify gaps, establish the context for a new study, and highlight the current state of knowledge in the field.

(j) What is the difference between Research Proposal and Synopsis ?

Ans: A research proposal is a detailed plan outlining the research study’s objectives, methods, and significance, submitted for approval before the research begins. A synopsis, on the other hand, is a brief summary or outline that provides an overview of the research project, typically used for initial screening or presentation purposes.

GROUP-B

(a) What is Null and Alternative Hypothesis ?
Ans: The null hypothesis (H0) posits no effect or relationship, while the alternative hypothesis (H1) suggests a significant effect or relationship. In hypothesis testing, statistical analysis aims to accept or reject the null hypothesis based on the observed data.

(b) What is Interview Method?
Ans: The interview method is a qualitative research technique where a researcher conducts direct, face-to-face conversations with participants to gather information. It allows for in-depth exploration of topics, opinions, and experiences, providing richer insights compared to surveys.
(c) What is Non-probability Sampling?
Ans: Non-probability sampling is a sampling technique where the selection of participants is not based on random chance. Participants are chosen deliberately, often due to their accessibility, convenience, or the researcher’s judgment. This method may lead to biased samples but is practical in certain research situations.
(d) What do you mean by Research Ethics?
Ans: Research ethics involve principles and guidelines that ensure the responsible conduct of research. It includes integrity, transparency, and respect for participants’ rights. Adhering to ethical standards prevents harm, maintains confidentiality, and upholds the credibility and validity of the research process.

GROUP-C

(a) Discuss the characteristics of a good Sample.
Ans: A good sample in research possesses several key characteristics. Firstly, it should be representative of the larger population under study to ensure the findings are generalizable. Random selection enhances representativeness. Secondly, the sample size must be sufficient for statistical reliability; too small a sample may lead to skewed results. Additionally, the sample should be homogeneous concerning relevant variables, minimizing confounding factors. The sample should also align with the research objectives, ensuring relevance and applicability of the findings. Moreover, the sampling method, whether probability or non-probability, should be clearly justified and described. Ethical considerations are paramount, requiring informed consent and protection of participants’ rights. Longitudinal studies may demand specific sampling strategies to capture changes over time. Lastly, a good sample enhances external validity, enabling researchers to generalize findings beyond the study context. Balancing practical constraints with these characteristics is crucial. Careful consideration of these aspects contributes to the overall rigor and reliability of the research outcomes.

(b) What is Research Design? What are the features of a good Research Design.?
Ans: Research design refers to the plan or blueprint outlining the structure and strategy of a research study. It involves decisions about data collection methods, sampling, time frame, and analysis. Features of a good research design include:

  1. Clear Objectives: Clearly defined research objectives guide the design, ensuring that the study addresses specific questions or issues.
  2. Validity: The design should measure what it intends to measure, ensuring the accuracy and relevance of the collected data.
  3. Reliability: The design should yield consistent results upon repetition, providing stability and dependability in the findings.
  4. Feasibility: The design must be practical and achievable within resource constraints, including time, budget, and available expertise.
  5. Sampling Strategy: The sampling method should be appropriate, considering the research objectives and ensuring the representation of the target population.
  6. Data Collection Methods: Selecting suitable tools and techniques for data collection, whether qualitative or quantitative, ensures the research’s success.
  7. Time Frame: A well-defined timeline helps manage the research process efficiently and ensures timely completion.
  8. Ethical Considerations: A good research design adheres to ethical standards, safeguarding participants’ rights and ensuring the integrity of the study.
  9. Flexibility: The design should accommodate unforeseen challenges or changes, allowing adjustments without compromising the research’s validity.
  10. Analysis Plan: Clearly outline the data analysis methods to draw meaningful conclusions and interpretations from the collected data

(c) Discuss its Merits and Demerits of Interview .
Ans: 

Merits of Interviews:

 

  1. In-depth Information: Interviews allow researchers to gather detailed and in-depth information, providing insights into participants’ perspectives and experiences.
  2. Flexibility: The interviewer can adapt questions based on responses, probing further into interesting areas, allowing flexibility in exploring complex issues.
  3. Non-Verbal Cues: In face-to-face interviews, non-verbal cues such as body language and facial expressions provide additional contextual information.
  4. Clarification: Interviewers can clarify ambiguous responses, ensuring a better understanding of participants’ viewpoints.
  5. Personal Connection: Interviews facilitate a personal connection between the researcher and the participant, fostering a comfortable environment for open communication.

Demerits of Interviews:

  1. Subjectivity: Interviews may introduce interviewer bias, influencing participants’ responses based on the interviewer’s characteristics or preconceptions.
  2. Time-Consuming: Conducting interviews is often time-consuming, especially in qualitative research where in-depth exploration is necessary.
  3. Resource Intensive: Interviews require skilled interviewers, training, and substantial resources, making them potentially more expensive compared to other data collection methods.
  4. Social Desirability Bias: Participants may provide socially desirable responses, conforming to perceived societal norms rather than expressing their true opinions.
  5. Limited Generalizability: Findings from interviews may be specific to the interviewed individuals and may not be easily generalized to a broader population.
  6. Interviewer Effect: The personality, demeanor, or characteristics of the interviewer can influence participants’ responses, affecting the reliability of the data.


(d) Discuss different types of Probability Sampling.

Ans: 

  1. Simple Random Sampling:

    Every individual in the population has an equal chance of being selected.

    Selection is entirely random, often facilitated by random number generators.

  1. Stratified Random Sampling:

    Population divided into subgroups (strata) based on certain characteristics.

    Random samples are then taken from each stratum proportionate to its size.

  1. Systematic Random Sampling:

    Researchers choose every kth individual from a list after randomly selecting a starting point.

    Useful when a complete list of the population is available.

  1. Cluster Random Sampling:

    Population divided into clusters, and a random sample of clusters is selected.

    All individuals within the chosen clusters are included in the study.

  1. Multistage Sampling:

    Involves a combination of various sampling methods.

    Researchers may use a mix of, for example, cluster and stratified sampling.

  1. Probability Proportional to Size Sampling:

    Selection probability is directly proportional to the size of each unit in the population.

    Larger units have a higher chance of being selected.

  1. Adaptive Sampling:

    A form of sequential sampling where the sampling process adapts based on the data collected.

    Adjustments made during the study based on emerging patterns.
