The more realistic it is the easier it can be applied to the population.

Q

What are Extraneous variables?

A

Extraneous variables are things about participants that affect results. (eg. age gender, culture)
Also does not change systematically with the independent variable but may have an affect on the dependent variable.

Q

What is the Confounding variable?

A

Confounding variables are mistakes that the researcher has made(situational factors) (time,location) .

  • They do not vary systematically with the IV.

  • Have high internal validity
  • Tend to have low ecological validity
  • Has confounding variables

Q

What are the features of a Natural experiment?

Q

What is Temporal validity?

A

Temporal validity is how well results apply as time goes on.

32
Q

What is Construct validity?

Q

What is a Pilot study?

A

Small scale test run of study. (looking for possible improvements.)

37
Q

What is a Directional hypothesis?

A

A hypothesis that states the expected direction of results. (People who work in front of tv produce LESS work than without.)

38
Q

What is a Non directional hypothesis?

A

A hypothesis that states the difference but not the direction. (people who work in front of the tv produce a different amount of work than people who don’t.)
