(Correct) (C) Probability samples are easier and less expensive to obtain, while non-probability samples are more time-consuming. (Incorrect) (D) Probability samples are used in qualitative research, while non-probability samples are used in quantitative research. (Incorrect)
Probability samples (e.g., random sampling, stratified sampling) ensure every member of the population has a known chance of being selected, enhancing generalizability.
Non-probability samples (e.g., convenience sampling, snowball sampling) rely on non-random selection methods, making generalization to the population difficult. However, they can be useful for exploratory research or when obtaining a random sample is impractical.
62. What are some potential benefits of using a mixed methods research design (combining quantitative and qualitative approaches)?
(A) Mixed methods research is simpler and less time-consuming than using a single approach. (Incorrect) (B) Mixed methods research can provide a more comprehensive and nuanced understanding of a phenomenon. (Correct) (C) Mixed methods research is less rigorous compared to using a single method. (Incorrect) (D) Mixed methods research is the preferred approach for all research projects. (Incorrect)
Explanation: While more complex than using a single method, mixed methods research offers advantages:
Provides a more complete picture by capturing both quantitative data (numbers, patterns) and qualitative data (experiences, perspectives).
Allows for triangulation, where findings from different approaches are compared to strengthen the overall research conclusions.
63. What is the importance of reliability and validity in research?
(A) Reliability is more important than validity in research. (Incorrect) (B) Reliability and validity are independent concepts; you only need one for good research. (Incorrect) (C) Reliability and validity are interrelated; a study needs to be both reliable and valid to be trustworthy. (Correct) (D) Reliability and validity are only relevant in quantitative research, not qualitative research. (Incorrect)
Explanation: Reliability and validity are crucial for ensuring the trustworthiness of your research: Reliability refers to the consistency of your findings. Would you get similar results if you repeated the study? Validity refers to whether your research measures what it claims to measure. Are you truly capturing the phenomenon you're interested in?
64. What are some ethical considerations when conducting research online?
(A) There are no specific ethical considerations when conducting research online. (Incorrect) (B) Researchers should obtain informed consent from participants and ensure data privacy and confidentiality. (Correct) (C) Researchers can deceive participants online to avoid bias in their responses. (Incorrect) (D) Online research does not require ethical review since participants are anonymous. (Incorrect)
Explanation: Online research requires attention to ethical considerations like: Informed consent: Participants should understand the research purpose, data collection methods, and how their data will be used. Privacy and confidentiality: Researchers should take steps to protect participant anonymity and secure data storage. * Deception: Deception should be minimized, and if used, participants should be debriefed after the research.
65. What is the role of theory in research?
(A) Theory provides a step-by-step guide for conducting your research. (Incorrect) (B) Theory offers a framework for understanding your research question and interpreting your findings. (Correct) (C) Theory is not necessary for all research projects. (While not always required, theory can be very helpful) (D) The main role of theory is to impress reviewers with your knowledge of the field. (Incorrect)
Explanation: Theory plays a significant role in research by: Providing a foundation for your research question and guiding your data collection and analysis. Offering a lens to interpret your findings and situate them within a broader context of knowledge. * Helping you identify gaps in existing theory that your research can address.
66. What is the difference between a one-tailed hypothesis and a two-tailed hypothesis?
(A) A one-tailed hypothesis predicts a specific direction for the relationship between variables (e.g., higher X leads to lower Y), while a two-tailed hypothesis predicts just a difference (positive or negative) between X and Y. (Correct) (B) One-tailed hypotheses are easier to test statistically, while two-tailed hypotheses are more complex. (Incorrect) (C) One-tailed hypotheses are used in qualitative research, while two-tailed hypotheses are used in quantitative research. (Incorrect) (D) There is no difference; they are the same type of hypothesis. (Incorrect)
One-tailed hypothesis specifies the expected direction of the effect (e.g., studying if stress increases blood pressure).
Two-tailed hypothesis predicts a difference between variables but doesn't specify the direction (e.g., investigating the relationship between exercise and mood, which could be positive or negative).
67. What is the main purpose of a codebook in qualitative research?
(A) A codebook is a pre-determined set of categories for coding qualitative data. (Correct) (B) A codebook is a detailed record of all the references used in your research. (Incorrect) (C) A codebook is a script used when conducting interviews or focus groups. (Incorrect) (D) A codebook is not necessary for all qualitative research projects. (Incorrect)
Explanation: A codebook is a systematic way to organize and analyze qualitative data. It defines codes (categories, themes) and their definitions, ensuring consistency in how data is interpreted and categorized.
68. What is the difference between descriptive statistics and inferential statistics?
(A) Descriptive statistics summarize data from your sample, while inferential statistics make generalizations about the population. (Correct) (B) Descriptive statistics are used in qualitative research, while inferential statistics are used in quantitative research. (Incorrect) (C) Descriptive statistics are more complex than inferential statistics. (Incorrect) (D) Both descriptive and inferential statistics aim to make generalizations about the population. (Incorrect)
Descriptive statistics summarize data from your sample using measures like mean, median, mode, frequency tables, and graphs.
Inferential statistics use sample data to draw conclusions (inferences) about the population from which the sample was drawn (e.g., hypothesis testing).
69. What is the difference between content validity and face validity in research?
(A) Content validity refers to the instrument's ability to measure the intended construct, while face validity refers to whether the instrument appears to measure what it claims to measure. (Correct) (B) Content validity is more important than face validity in research. (Incorrect) (C) Content validity is assessed through statistical analysis, while face validity is based on subjective judgment. (Incorrect)** (D) There is no difference; they are the same concept. (Incorrect)
Content validity: Does the research instrument (survey, interview questions) adequately capture the intended concept or variable?
Face validity: On the surface, does the instrument appear to measure what it claims to measure? (Judged by researchers or participants)
70. What are some potential challenges of conducting research with a culturally diverse population?
(A) Researchers may need to adapt their research instruments and data collection methods to accommodate cultural differences. (Correct) (B) Culturally diverse populations are generally less willing to participate in research studies. (Incorrect) (C) Cultural diversity strengthens the generalizability of research findings. (Not always true) (D) Researchers with similar cultural backgrounds as the participants are best suited for such studies. (Incorrect)
Explanation: Conducting research with culturally diverse populations requires sensitivity to:
Language barriers: Translation issues, needing culturally appropriate instruments.
Cultural norms: Adapting data collection methods to avoid offending or misinterpreting responses.
Power dynamics: Ensuring informed consent and building trust with participants from different backgrounds.
You are interested in exploring the lived experiences of single parents raising teenagers during the COVID-19 pandemic. What research design would be most appropriate for this study, and why?
(A) Experiment: Not suitable as it involves manipulating variables, not exploring experiences. (B) Survey: Could gather general information but wouldn't capture the depth of lived experiences. (C) Case study: Useful for in-depth exploration of a single case, but limitations in generalizability. (D) Phenomenological research design: This qualitative approach focuses on understanding the lived experiences of individuals, making it a strong choice for your research question.
Explanation: Phenomenological research design is ideal for exploring subjective experiences and understanding how participants make sense of their experiences.
