PSY220: Social Psychology Midterm 1
questions well answered
hypothesis - correct answer ✔✔a testable prediction about the conditions needed for an event
to occur
theory - correct answer ✔✔a set of principles used to explain observations
basic research - correct answer ✔✔expands our understanding of human behaviour, but is not
meant to test a hypothesis (ie. how does caffeine affect brain function, what are the
components of DNA)
applied research - correct answer ✔✔figures out how something works in the real world and
provides a solution to social issues (ie. how to encourage people to wear masks during a
pandemic, how to discourage bullying online)
validity - correct answer ✔✔the extent to which a test measures what it claims to measure
reliability - correct answer ✔✔the consistency of results /measurements when reproduced
interrater reliability - correct answer ✔✔the consistency of multiple judges to score in
agreement with each other
descriptive research - correct answer ✔✔describes observations and how variables interact
without experimental manipulation (ie. observing how kids interact with each other at the
playground)
, correlational research - correct answer ✔✔tests how similar/different variables are, how they
change together and whether we can predict their changes (ie. measuring job satisfaction of
high income earners compared to low income earners)
experimental research - correct answer ✔✔uses variable manipulation to determine a cause
and effect relationship, need controls and random assignment (ie. does amount of sleep predict
exam test scores)
random sampling - correct answer ✔✔random selection of people to participate in a study to
represent population
random assignment - correct answer ✔✔random selection of participants to the experimental
groups to ensure variable changes are not due to individual differences
independent variable - correct answer ✔✔variable that is manipulated (ie. hours of sleep)
dependent variable - correct answer ✔✔variable that changes to due the independent variable
and we measure (ie. exam score)
subject variable - correct answer ✔✔pre-existing variable (ie. stress levels, age, intelligence)
statistical significance - correct answer ✔✔determines the degree to which results arose due to
chance, statistically significant if results arose by chance less than 5% of the time
internal validity - correct answer ✔✔the extent to which results actually explain the population
external validity - correct answer ✔✔the extent to which results generalize to other
populations/situations
