Answer 1

Case Study

Question 2

What are the 3 perks of case studies?

Hard to generalize (can not assume everyone will be like this)

Question 4

What research method is to establish a relationship between 2 variables?

Answer 9

Research by experiment

Question 10

What is the difference between an experimental group and a control group?

Answer 10

Answer 11

Random assignment

Question 12

What are the two perks of random assignment?

Answer 12

1. Removes systematic differences between the groups
2. Any differences between groups are random

Question 13

What is the goal of research by experiment?

Answer 13

Hope to be able to prove the IV is what affects the DV

Question 14

What is the main perk of experimental design?

Answer 14

Better able to attribute causality

Question 15

What are the two disadvantages of experimental designs?

Answer 15

1. Certain variables cannot be manipulated
2. Expensive/time consuming

Question 16

Answer 16

Confounds

Answer 17

Confounds

Question 18

What is the extent to which you can be sure the IV caused the DV?

Answer 18

Internal validity

Question 19

What is the extent to which you can be sure the study is generalizable?

Answer 19

External validity

Question 20

Within group means that________________

Answer 20

everyone is getting the treatment

Question 21

As you increase internal/external, the other ____________

Answer 21

Decreases

Question 22

Compares to another group that are the same without the exposure to experimental treatment

Answer 22

Control group

Question 23

Hoping for a group with similar characteristics

Answer 23

Random assignment

Question 24

Neither researchers nor participants know who is in the experimental or control group

Answer 24

Double bind
