Methods of Enquiry in Psychology Class 11 Notes: Chapter Overview

Chapter 2 explains how psychology becomes a scientific subject. Psychologists do not only ask interesting questions. They define problems, collect data, analyse evidence and revise conclusions. The safest exam line is simple: method makes psychological enquiry systematic, objective and testable.

Goals of Psychological Enquiry

NCERT lists five goals of psychological enquiry: description, prediction, explanation, control and application. Description records behaviour accurately. Prediction uses relationships to forecast behaviour. Explanation searches for causes. Control changes behaviour by changing conditions. Application uses knowledge to improve life.

• Description: record what the behaviour is.
• Prediction: forecast when it may occur.
• Explanation: identify determinants or antecedent conditions.
• Control: reduce, increase or produce a behaviour.
• Application: use findings in real settings.

Scientific Research Steps in Psychology

Scientific research begins with conceptualising a problem. The researcher then collects data through a suitable design, draws conclusions and revises the conclusion or theory if the evidence requires it. This cycle keeps research open to correction.

Nature and Types of Psychological Data

Psychological data are connected with context. A person may behave differently at home, in school, alone or in a group. Data are also tied to the method used, the theory guiding the study and the time of observation.

• Demographic data: age, gender, education, family and locality.
• Physical data: housing, facilities, transport and ecological setting.
• Physiological data: heart rate, fatigue, reaction time, sleep and blood pressure.
• Psychological data: intelligence, personality, values, emotions, motivation and subjective experience.

Observation, Experiment and Correlation

Observation records selected behaviour in a planned way. Experiment studies cause and effect by manipulating an independent variable and observing a dependent variable. Correlation studies relationship between two variables for prediction, but it does not prove causation.

Survey, Interview, Questionnaire and Testing

Survey research collects opinions, attitudes and social facts. Interviews allow depth and probing. Questionnaires are low-cost and useful for many people at once. Psychological tests measure attributes such as intelligence, aptitude, personality, interest and values through standardised items.

1. Structured interviews use fixed questions in a fixed order.
2. Unstructured interviews allow flexible questioning.
3. Questionnaires may use open-ended or closed-ended questions.
4. Tests must be reliable, valid and standardised.

Case Study, Data Analysis, Limits and Ethics

A case study gives an in-depth account of a person, small group, institution or event. It can use interviews, observation and tests together. Data analysis may be quantitative, using scores and statistics, or qualitative, using meaning, narrative and context.

NCERT gives three main limitations of psychological enquiry. Psychological measurement has no true zero point, psychological tools are relative to the context in which they are made, and qualitative data need careful interpretation. These points are important for NCERT Review Question 11.

Ethics are central because psychological research studies real people. Students should connect ethics with voluntary participation, informed consent, debriefing, sharing results and confidentiality. These five guidelines are the safest structure for NCERT Review Question 12.
