Question 4

What is a pilot study?

Answer 4

• A simple study using different participants to confirm the experiment works
• Is a model before the larger study to check the basics

Question 5

What is external validity?

Answer 5

• The hardest for experiemental work because lab settings are artificial, so generalizing to other people is hard
• Labs often use convenience sampling, such as college students who are: 18-22 yo, smarter than average, more money, etc… so is this truly generalizable

can replicate with similar experiments + stimuli to help counteract

Question 6

What is statistical validity?

Answer 6

• For determining how large the effect is, and how big is the difference between the groups
• To measure, you look at data/stats
• Calculate effect size (d). Large d=large effect size.
• Confidence interval: 95% conrident we get a score in this range (if the effect is true). Shows the effect is real and meaningful
