Methods of Enquiry in Psychology
Class 11 · Psychology
4 ideas in Class 11 Psychology, explained in plain words, with games and quizzes to practise.
Goals of Psychological Enquiry
Part of: Goals, data and first methods
Psychological enquiry has clear goals: first describe what happens, then predict what may happen, explain why it happens, control conditions to check causes, and apply findings to real life. A study of exam fear moves from noting shaking hands to forecasting who struggles, finding the causes, testing a calm-down routine and guiding schools.
Why it matters. Without these goals, learners collect random facts or jump to quick fixes. Knowing the goals helps them ask sharper questions and judge whether a claim merely describes or truly explains.
Key words
- Description
- : Careful noting of what happens, when and with whom.
- Prediction
- : A forecast of what may happen based on known links.
- Explanation
- : Finding the causes behind an observed pattern.
- Control
- : Holding conditions steady so one factor can be checked.
- Application
- : Using tested findings to solve real-life problems.
Try it in two minutes
- Ask the learner to name one behaviour they have noticed, such as phone use at night.
- Ask what they would forecast about marks from that habit.
- Ask what hidden cause might explain the link.
- Ask how they would test one small change fairly.
Try at home. Pick one home habit and write one line for each goal: describe it, predict from it, explain it and change it.
Observation and Experiment
Part of: Goals, data and first methods
Observation means watching behaviour with a plan, either openly in daily life or from hiding so people act naturally. An experiment goes further: the researcher changes one factor, keeps the rest steady and measures the result. The changed factor is the independent variable, the measured result is the dependent variable, and the untouched group is the control group.
Why it matters. Learners often accept any single lively example as proof. These methods teach them to separate careful watching from tested causes, a skill useful in every subject.
Key words
- Naturalistic observation
- : Watching behaviour in its usual setting without changes.
- Participant observation
- : Watching while joining the group being studied.
- Independent variable
- : The factor the researcher changes in an experiment.
- Dependent variable
- : The result the researcher measures in an experiment.
- Control group
- : The untouched group used for comparison.
Try it in two minutes
- Ask the learner to watch birds or traffic for two minutes and note three facts.
- Ask what they changed and what they only watched.
- Ask what they would change and measure in a small test.
- Ask who would form the untouched comparison group.
Try at home. Watch a busy shop corner for ten minutes, note who stops, and list one factor you would test.
Correlation Survey Testing and Case Study
Part of: More methods, analysis and ethics
When experiments are not possible, psychologists use other tools. Correlation measures how two traits move together. Surveys ask many people the same questions quickly. Psychological tests measure traits like aptitude in a fixed way. A case study follows one person or unit deeply over time, which suits rare conditions.
Why it matters. Learners often read a survey result as proof of cause or trust any printed test. Knowing what each tool can and cannot show protects them from such mistakes.
Key words
- Correlation
- : How strongly two traits change together, from minus one to plus one.
- Survey
- : Same questions asked to many people to map views fast.
- Psychological test
- : A fixed task set that measures a trait in the same way.
- Reliability
- : Giving steady results when used again.
- Case study
- : Deep study of one person or unit over time.
Try it in two minutes
- Ask the learner to name two habits that rise together, such as practice and scores.
- Ask if one surely causes the other, and why not.
- Ask when asking many people fast would help.
- Ask when studying one person deeply would help.
Try at home. Survey five neighbours on one question, note the pattern, and write what it cannot prove.
Analysis Limits and Ethics
Part of: More methods, analysis and ethics
After gathering data, psychologists analyse it: numbers and graphs give quantitative results like averages, while words and diaries give qualitative meanings. Enquiry has limits because people change, hide facts and differ across settings. Ethics then demands free consent, privacy, no harm and an honest debrief at the end.
Why it matters. Learners may trust any average blindly or ignore the rights of people studied. This idea teaches them to read numbers with care and to insist on fair treatment of participants.
Key words
- Quantitative method
- : Analysis using numbers, counts and graphs.
- Qualitative method
- : Analysis using words, meanings and lived events.
- Average
- : A single number summing up a set of scores.
- Informed consent
- : Free agreement to join after learning the study.
- Debriefing
- : Explaining the true purpose after the study ends.
- Confidentiality
- : Keeping participant names and details private.
Try it in two minutes
- Show the learner five family ages and find the middle value together.
- Ask what one very old value does to the average.
- Ask what must be told before someone joins a study.
- Ask what must be told after a study that hid its aim.
Try at home. List the ages of five relatives, find the average and the middle value, and note how they differ.
