Week 3: Research Methods

  1. Please indicate which of the following is true about surveys as a design study.
    1. Surveys belong to the category of True Experiments.
    2. Surveys belong to the category of Quasi Experiments.
    3. Surveys belong to the category of Non-Experiments.
    4. All of the above are true.
  2. You have been tasked by TU Delft to administer a survey to first year MSc students on the perceived study-life balance. This survey is intended for the first year MSc students of all faculties within TU Delft. Describe how you will define the different strata within your target populations and what aspects will you consider while conducting stratified random sampling to ensure less bias and error in survey responses?
  3. Suppose you are planning to conduct a survey to capture the different usage patterns of ChatGPT among students at TU Delft. Therefore, you only recruit participants who have used ChatGPT in their studies. This kind of sampling approach is referred to as?
    1. Random Sampling.
    2. Snowball Sampling.
    3. Intercept Sampling.
    4. Non-probabilistic Sampling.
  4. Imagine that you and your friend have been tasked with the analysis of interview data. The interview was conducted with high-school teachers about the perceived relevance of a NEW smart awareness tool that can inform them about the levels of attention and fatigue of students in classroom. In this way, the teachers can potentially better self-regulate their teaching pace. Since, this is an entirely new product which has not been tested or analyzed in any other context, and assuming that no theoretical frameworks exist to explain the phenomena, which coding approach would you use (Emergent or A Priori) and why? Also illustrate the different stages of the coding process that you will follow.
  5. What is the primary objective of grounded theory in qualitative research?
    1. To test pre-existing hypotheses and theories.
    2. To establish causal relationships between variables.
    3. To generate new theories and conceptual frameworks based on data.
    4. To confirm the validity of existing theories through empirical evidence.
  6. Which of the following statements best describes Cohen’s Kappa in the context of inter-rater reliability?
    1. Cohen’s Kappa measures the absolute agreement between raters, disregarding chance agreement.
    2. Cohen’s Kappa measures the consistency between raters beyond what would be expected by chance.
    3. Cohen’s Kappa measures the correlation between raters’ scores on a continuous scale.
    4. Cohen’s Kappa measures the difference in ratings provided by different raters.
  7. For each of the following use cases, please identify the specific kind of sampling error.
    • Coverage, Measurement or Non-response Error
    1. Majority (85%) of the respondents to the survey are men.
    2. Your survey, which was designed for Zuid-Holland, was only distributed in Rotterdam.
    3. You asked a few questions which were double-barreled in your survey.
    4. Asking respondents in your survey (administered in March) to report their emotional response to the moment they broke their new year resolution promises.
