Approaches to quantitative research

Full Answer Section

1. Quasi-experimental Research:

   • Focus: Similar to experimental research, but lacks random assignment to groups.
   • Methods: Non-equivalent groups designs, time-series designs.
   • Examples:
     • Evaluating the effectiveness of a new teaching method in different classrooms.
     • Studying the impact of a natural disaster on a community.

2. Survey Research:

   • Focus: To collect data from a large sample of individuals using questionnaires or interviews.
   • Methods: Questionnaires, interviews, online surveys.
   • Examples:
     • Measuring public opinion on political issues.
     • Assessing customer satisfaction with a product or service.

These are just a few examples of quantitative research approaches. The specific approach chosen will depend on the research question, the available resources, and the desired level of evidence.

Sample Answer

Here are 5 approaches to quantitative research:

1. Descriptive Research:

   • Focus: To systematically describe and summarize data about a population or phenomenon.
   • Methods: Surveys, observations, and case studies.
   • Examples:
     • Determining the prevalence of a disease in a population.
     • Describing the demographic characteristics of a particular group.

2. Correlational Research:

   • Focus: To examine the relationship between two or more variables.
   • Methods: Correlation coefficients (e.g., Pearson's r), regression analysis.
   • Examples:
     • Investigating the relationship between smoking and lung cancer.
     • Examining the correlation between income and education level.

3. Experimental Research:

   • Focus: To establish cause-and-effect relationships between variables.
   • Methods: Randomized controlled trials, laboratory experiments.
   • Examples:
     • Testing the effectiveness of a new drug compared to a placebo.
     • Determining the impact of a specific intervention on a particular outcome.
