Variables - ANSWER the events, characteristics, behaviors, or conditions that
researchers measure and study.
Subject or participant - ANSWER an individual person or animal a researcher studies.
Sample - ANSWER a collection of subjects researchers study. Researchers use samples
because they cannot study the entire population.
Population - ANSWER the collection of people or animals from which researchers
draw a sample. Researchers study the sample and generalize their results to the population.
The Purpose of Research - ANSWER -To find ways to measure and describe behavior
-To understand why, when, and how events occur
-To apply this knowledge to solving real-world problems
The scientific method - ANSWER a standardized way of making observations,
gathering data, forming theories, testing predictions, and interpreting results.
A theory - ANSWER an explanation that organizes separate pieces of information in a
coherent way.
Replicable - ANSWER when others can repeat an experiment and get the same results.
1
, Hypothesis - ANSWER a testable prediction of what will happen given a certain set of
conditions.
Naturalistic observation - ANSWER researchers collect information about subjects by
observing them unobtrusively, without interfering with them in any way.
Case study - ANSWER The researcher collects data about the subject through
interviews, direct observation, psychological testing, or examination of documents and
records about the subject.
Survey - ANSWER a way of getting information about a specific type of behavior,
experience, or event. When using this method, researchers give people questionnaires or
interview them to obtain information.
Experiment - ANSWER a researcher manipulates or changes a particular variable
under controlled conditions while observing resulting changes in another variable or
variables.
Occam's razor - ANSWER maintains that researchers should apply the simplest
explanation possible to any set of observations.
Correlation - ANSWER measurement of the strength of the relationship between two
variables
Reliability - ANSWER if a test produces the same result when researchers administer it
to the same group of people at different times, it has reliability.
Validity - ANSWER A test is valid if it actually measures the quality it claims to
measure.
