|
|
|
Hypothesis
|
Testable explanations of observed events; "If..then.."
|
|
|
Reliability
|
Study produces consistent results when replicated so it's ______
|
|
|
Validity
|
THE EXTENT TO WHICH A TEST MEASURES OR PREDICTS WHAT IT IS SUPPOSED TO
EX: A TEST THAT SAYS THAT THE CHANCES OF YOU GETTING CANCER DEPEND ON THE WEIGHT OF YOUR HEAD IS NOT VALID BECAUSE ITS NOT MEASURING WHAT ITS SUPPOSED TO. |
|
|
Content Validity
|
REFERS TO HOW WELL A TEST MEASURES THE BEHAVIOR FOR WHICH IT IS INTENDED
EX: A DRIVING TEST WILL MEASURE YOUR ABILITY AT CERTAIN DRIVING TASKS, SO ITS VALID |
|
|
Internal Validty
|
Study shows that only the experimental factor caused an affect
|
|
|
External Validity
|
results of study apply to other situations
|
|
|
Correlation Study
|
expresses the relationship between 2 variables; DOES NOT IMPLY CAUSATION
|
|
|
Experiment
|
the manipulation of an IV to understand its effect on a DV; Identifies Cause-effect
|
|
|
Sampling
|
The process of choosing subjects to study
|
|
|
Sample
|
Group of subjects selected for study; a subset of a population
|
|
|
Population
|

|
|
|
Random assignment
|
random placement of subjects into experimental or control groups
|
|
|
Control group
|
group that stays the same; not subjected to experimental manipulation
|
|
|
Variables
|
things that can vary among subjects
|
|
|
Independent Variable
|
Variable that I change; produces a change in the DV
|
|
|
Dependent Variable

measured by the researcher
|
|
|
Confounding Variable
|
any possible variable- other than the IV - that may cause the observed effect
|
|
|
Frequency distribution
|
an arrangement of data points based on how frequently they occur
|
|
|
Normal Distribution
|
Frequency distribution with the shape of a normal curve ( a symmetrical bell shaped curve)
|
|
|
Central tendency
|
measures of the center of the frequency distribution : Mean, Median, Mode
|
|
|
Variability
|
how the data are spread around the mean
|
|
|
Standard deviation
|
average distance of a data point from the mean; small = scores relatively close to the mean; large = scores have a wider range around the mean
|
|
|
Statistical significance
|
means that the differences observed are too big to have occurred by change
|
