Question 2

research question

Answer 2

classifies your study-able answer

Question 3

Answer 3

why do you expect to find

Question 4

theories (), hypothesis () research ()

Answer 4

explain
predict
tests

Question 5

deductive reasoning

Answer 5

Theory testing: allows us to collect evidence that may show a theory to be a good/bad explanation for the way people behave
Theory → observation (general premise to specific cases)
Theory driven

Question 6

inductive reasoning

Answer 6

Theory building: allows researchers to suggest explanation ofr the way people behave
Observation → theory (specific → general observation)
Data driven

Question 16

Longitudinal

Question 17

types of experiments

Answer 17

true experiments, field experiments, quasi experiments, natural experiments

Question 18

true experiments

Answer 18

Participants are randomly assigned to the conditions to control for extraneous variables. True experiments are excellent for showing a cause-and-effect relationship

Question 19

field experiments

Answer 19

Experimental investigation carried out in a natural environment- the deliberate manipulation of IV

Question 20

quasi expeiments

Answer 20

A change is implemented, but participants are not randomly assigned to conditions

Question 21

natural experiments

Answer 21

The researcher makes use of naturally occurring differences in IV- the IV is not directly manipulated

Question 22

between group designs

Answer 22

Compare different participants in different conditions

Question 23

within group designs

Answer 23

Compare same participants in both conditions

Question 24

validity

Answer 24

Are you measuring what you hope you are measuring
Accuracy
The ability of a test to measure what is designed to measure, or the degree to which a test accurately measures what it’s supposed to measure

Question 25

reliability

Answer 25
