Study Notes

Data Collection and Organization

Free model
  • Surveys/Questionnaires: You ask people questions directly, often through written forms or online polls. This is great for opinions, attitudes, or demographic information.
    • Example: Asking 10th graders about their favourite school subject.
  • Observations: You watch and record behaviours or events without directly interacting. Useful for studying natural phenomena or behaviour.
    • Example: Counting how many cars pass a certain intersection during rush hour.
  • Experiments: You manipulate one or more variables to see their effect on another variable. This is common in science to establish cause-and-effect.
    • Example: Testing if a new teaching method improves test scores by comparing two groups of students.
  • Existing Data (Secondary Data): You use data that someone else has already collected. This could be government reports, company records, or previous research studies.
    • Example: Using census data to find out the average household income in your city.
