psychology chapter 2

Question 1

correlation method

Answer 1

descriptive finding can be analyzed to determine the relationship between different behaviours, events or any variable

Question 2

experimental method

Answer 2

formulate a hypothesis- design a study to test that hypothesis

Question 3

descriptive methods

Answer 3

provide different ways to describe behaviour without any attempt to interfere with the behaviour under study (naturalistic observation, case study, surveys)

Question 4

naturalistic observation

Answer 4

observing people in their natural habitats without them knowing

Question 5

case study

Answer 5

studying a single individual

Question 6

median

Answer 6

middle

Question 7

control condition

Answer 7

not exposed to the independent variable

Question 8

distributions

Answer 8

graph the data then understand how the scores are distributed

Question 9

evaluating research

Answer 9

sampling bias, placebo effects, double-blind study

Question 10

mean

Answer 10

add them all and divide by the amount AVERAGE

Question 11

positive and negative correlation

Answer 11

positive- both variables change in the same direction

negative- both variables change in opposite directions

Question 12

skewed distributions

Answer 12

mean, median and mode usually differ
negatively- goes to left towards lowest score
positively-goes to right toward higher scores

Question 13

the normal curve

Answer 13

symmetrical, mean median and mode are identical

Question 14

measures of variability

Answer 14

indicates the spread of the scores about the mean
low- near mean
high- distributed

Question 15

measures of central tendency

Answer 15

mean median and mode

Question 16

inferential statistics

Answer 16

differences found between groups due to chance or due to actual differences

Question 17

correlation coefficient

Answer 17

measure of both the direction and strength of a correlation (r)
+ change in the same direction
- one increases one decreases

Question 18

mode

Answer 18

most frequent

Question 19

experimentation

Answer 19

establishing the casual relationship between variables, allows for manipulation

Question 20

hypothesis

Answer 20

a falsifiable prediction made by a theory

Question 21

double-blind study

Answer 21

researchers and participants both don’t know how participants are supposed to behave
solution for bias

Question 22

scientific method

Answer 22

using empirical evidence to establish facts
