H8: Experimental Research

Question 1

Experimental Research

Answer 1

Manipulating at least one variable and measure at least one other variable

Question 2

lab experiment

Answer 2

artifical environment (when you maximum control)

Question 3

field experiment

Answer 3

natural setting (when to measure real-world situation and long-term effects of manipulations)

Question 4

control group

Answer 4

level of IV that represents a neutral condition

Question 5

threatment group

Answer 5

the other levels of the variables

Question 6

between subjects design

Answer 6

different group of subjects are assigned to different levels of the IV

Question 7

within subjects design

Answer 7

each subject is presented with all levels of IV

Question 8

why only use a posttest-only design?

Answer 8

pretest could influence behaviour

Question 9

factorial design

Answer 9

• design with more than one IV
• test for interaction/moderating effects

Question 10

mixed factorial design

Answer 10

one IV is manipulated as between-subjects. One iV is manipulated as within-subjects

Question 11

reliability multi-item

Answer 11

cronbach’s aloha (>.070)

Question 12

validity measured/manipulated variables

Answer 12

• providing precedence
• using sound logic
• manipulation check (to determine effectiveness of a manipulation)
