Question 4

Answer 4

high control of variables within an environment
enables researcher to minimise extraenous variables
high IV so more control of IV
low external validity

Question 5

What is a field experiment?

Answer 5

takes place in a natural setting
more realistic than lab experiment
high external validity
lack of control of extraenous variables and ppts cannot consent in being part of the research initially
low reliabilityW

Question 6

What is a natural experiment?

Answer 6

IV is naturally occurring
researcher hasnt changed the IV and would happen regardless of research
high external validity
rare opportunities of research

Question 7

Answer 7

accept alternative hypothesis
instead of the null hypothesis

Question 8

What is a type 2 error?
