Research Methods in Psychology

This video tutorial covers various research methods, including experiments, interviews, questionnaires, observations, case studies, and correlations. It explains the types of experiments (lab, field, and natural) and their evaluations, structured and unstructured interviews, and the use of open and closed questions in questionnaires. The video also discusses different types of observations, characteristics of case studies with examples, and understanding correlations with their representation.

Which type of experiment involves manipulating the independent variable in a controlled environment?

• Field experiment

• Natural experiment

• Case study

• Lab experiment

What is a key disadvantage of lab experiments?

• High ecological validity

• Unethical if participants are unaware

• Difficult to replicate

• Poor ecological validity

In a structured interview, how are the questions presented?

• In a random order

• In a pre-planned and fixed order

• Based on participant's responses

• Without any pre-planning

What is a potential issue with closed questions in questionnaires?

• They are difficult to standardize

• They are time-consuming to analyze

• They gather qualitative data

• They may not accurately capture participants' feelings

Which type of observation involves participants being unaware they are being observed?

• Covert observation

• Overt observation

• Controlled observation

• Participant observation

What is a strength of controlled observations?

• High ecological validity

• Lack of control over variables

• Ability to show cause and effect

• Participants are unaware of being observed

What is a characteristic of case studies?

• They involve large groups of participants

• They provide in-depth data

• They are easy to generalize

• They rely on quantitative data

What does a correlation coefficient indicate?

• The number of participants in a study

• The strength and direction of a relationship between variables

• The number of variables in a study

• The qualitative data collected

What is a limitation of qualitative data in case studies?

• It is highly objective

• It is easy to analyze

• It is open to interpretation

• It is always reliable

In a positive correlation, what happens to the covariables?

• There is no relationship

• Both decrease

• One increases while the other decreases

• Both increase
