Instructions:
Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can
study here
.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

11. Extent to which a test yields consistent results - a measure is repeatable
reliability
correlation
double-blind procedure
experiment
12. Experimental factor that is manipulated; variable whose effect is being studied.

independent variable
random sample

13. Researchers takes subjects & conditions as they naturally occur - with little if any control over what happens. no random assignment so no cause and effect can be determined
positive (right) skew

range
14. Descriptive research that involves observing and recording behavior without trying to manipulate and control the situation.
naturalistic observation
random sample

alternate form reliability
15. Extent to which a test measures or predicts what it is supposed to - test accuracy

split half reliability
validity
construct validity
16. Effects of being born and raised in a particular time or situation where all other members of your group has similar experiences makes your group unique from others
scientific method
false consensus effect
frequency histogram
cohort effects
17. Not rejecting null hypothesis when in fact we should have rejected it - a false negative
type two error
random assignment
null hypothesis
hindsight bias
18. Graphed cluster of dots - each of which represents the values of two variables. The slope of the points suggests the direction of the relationship between the two variables.
quasi-experiment
p<.05
scatterplot
longitudinal research
19. Set of assumptions used to explain phenomena & offered for scientific study
case study
theory
interval data
experimental condition
20. A research method that looks like an experiment BUT subjects are not randomly assigned to control and experimental groups (no cause and effect can be drawn)
n
hindsight bias
meta analysis
quasi experiment
21. Condition of experiment that contrasts with experimental condition and serves as a comparison for evaluating the effect of the treatment.
illusory correlation
control condition
negative correlation
null hypothesis
22. Bar graph that shows frequency distributions
frequency histogram
control condition
quasi-experiment
cohort effects
23. Indication of how likely a result obtained occurred by chance - expressed as p or sig.

theory
split half reliability
26. Tendency to give socially approved answers to questions about oneself.
illusory correlation
placebo effect
ordinal data
social desirability bias
27. Relationship between variables in which as one variable increases - the other also increases - OR as one decreases so does the other. Both variables move in the same direction.
random assignment
quasi-experiment
positive (right) skew
positive correlation
28. A test is divided into 2 halves and scores on the halves are compared to see if test is consistent within itself. Ex. compare odds & evens
split half reliability
meta analysis
nominal data
frequency histogram
29. View that science flourishes through observation and experiment.
