A test taken in Year 10 accurately predicts exam results in Year 11. What type of validity is shown?
Predictive validity
A psychologist checks if participants score similarly on the first and second halves of a test. What is being tested?
Split-half reliability
A researcher wants to understand a rare condition, he choses one patient adn then conducts multiple studies involving this participant using a verity of methods. What method is this?
Case studies
A psychologist states their study 'seeks to explore the relationship between sleep and memory.' What is this an example of?
Research Aim
A psychologist wants to show how student preferences are split among 4 course options. What chart fits best?
Pie Chart
A psychologist uses fMRI to study memory-related brain activity. how would you describe this method of collecting data?
Brain scans
Participants say a questionnaire on anxiety looks like it measures anxiety. What type of validity is this?
Face validity
Interview responses describing how participants felt during a test are what type of data?
Qualitative data
A person completes a mood diary for 7 days. What kind of method is this?
Self-reports
A university team checks whether a study on anxiety meets ethical standards. What Ethical Process does it describe
Ethics Committee
A form of independent groups design where the experimental and control participants are deliberately similar
matched pairs
Observation carried out in the participants' usual environment without interference or manipulation
naturalistic observation
A study investigates whether sleep hours are related to stress levels. What method is this?
Correlational studies
Test scores ranged from 10 to 40. What is the range?
30
A research method where the researcher watches and records participants’ behaviour without interfering in any way (from a distance).
non-participant observation
A study compares exam results of people who experiences childhood trauma using an experimental method. What type of experiment is this?
Natural (quasi) experiments
A researcher studies development in the same group of children from ages 5 to 15. What method is this?
Longitudinal studies
A sampling technique where every member of the target population has an equal chance of being selected
Random Sampling
A diagram that represents frequencies of non-continuous data.
Bar chart
A participant finds out the study was about stress but was told it was about sleep. What ethical issue is this?
Deception
A behavioural observation technique where observations are made at fixed intervals
time sampling
Sampling technique where participants choose to take part,
A study measures attention before and after coffee in the same group. What design is used?
Repeated measures design
A study looks at whether hours studied correlates with exam score. What graph should be used?
Scatter graph
A technique where every nth person on a list of the population is selected
Systematic
A researcher counts how often themes of aggression appear in TV shows. What method is this?
Content analysis
A study records reaction time across 5 trials. What graph best shows this progression?
Line graphs
The extent to which a measure or study produces consistent results when repeated over time or with different researchers. Often tested using test-retest method.
External Reliability
A method where the population is divided into key subgroups (strata), and participants are randomly selected from each group
Stratified sampling
A researcher starts with fixed questions but probes deeper based on answers. What type of interview is this?
Semi-structured interviews
A researcher claims 'temperature will affect test performance.' Is this a directional or non-directional hypothesis?
Non-Directional
In a loud testing room, all participants struggle to focus. What kind of variable is this?
Extraneous variables
what does this mean "<"
Less than
A researcher defines aggression as 'number of times a child hits a doll.' What is this process called?
Operationalisation of variables
A research location where study is conducted in a controlled setting
Lab
The variable the psychologist manipulates and controls to see how it affects behaviour.
Independent Variable
A psychologist adds all test scores and divides by the number of participants. What measure is this?
Mean (measure of central tendency)
A psychologist records sleep and anxiety scores. What are these variables called in correlation research?
Co-variables
A complete list of the target population from which a sample is drawn.
sampling frame
A researcher compares stress levels of teens, adults, and elderly people on one day. What method is this?
Cross-sectional studies
The larger group of individuals a researcher is interested in studying and to whom they intend to generalise the results. Samples are selected from this group.
