Research Methods handbook

What is the primary difference between qualitative and quantitative research?

• Quantitative focuses on numerical data, while qualitative explores meanings and experiences
  

• Qualitative is more scientific than quantitative
  

• Quantitative only uses surveys, while qualitative only uses interviews
  

• Both methods always produce statistical results

When should a quantitative survey be used?

• When gathering in-depth opinions from a small group
  

• When collecting numerical data from a large population
  

• When analyzing historical records
  

• When conducting an unstructured interview

What is a key advantage of secondary data analysis?

• It allows researchers to control data collection
  

• It is time-efficient and cost-effective
  

• It always provides the most accurate information
  

• It does not require statistical analysis

What does ANOVA (Analysis of Variance) help researchers determine?

• The relationship between two qualitative variables
  

• Whether there are significant differences between multiple groups
  

• The number of participants needed for a study
  

• The total population size

5. Which of the following best describes a structured interview?

• A conversation with no pre-set questions
  

• An interview that follows a fixed set of questions systematically
  

• A group discussion where participants respond freely
  

• A type of statistical analysis

Why is pilot testing important in surveys?

• a) To make sure the survey questions are clear and understandable
  

• b) To increase the sample size
  

• c) To confirm that respondents will provide the same answers
  

• d) To eliminate the need for data analysis

What is the main purpose of confidence intervals in statistical analysis?

• a) To measure how much data is missing
  

• b) To estimate the range in which a population parameter is likely to fall
  

• c) To determine the relationship between two variables
  

• d) To compare two different research methods

What is a major limitation of using discussion groups (focus groups) in research?

• a) They do not allow open-ended responses
  

• b) Some participants may dominate the discussion, affecting results
  

• c) They are only useful for large-scale statistical research
  

• d) They always produce highly generalizable results

9. Which of the following is a qualitative research method?

• a) Regression analysis
  

• b) Social surveys with open-ended questions
  

• c) Hypothesis testing
  

• d) Descriptive statistics

What does the Chi-square test measure in research?

• a) The probability of obtaining the same results if the study were repeated
  

• b) Whether there is a significant relationship between categorical variables
  

• c) The differences in means between groups
  

• d) The total number of responses in a survey
