PSY 333 Midterm 1 Study Guide: Abnormal Psychology Foundations Review
What is the cutoff for normality in S-W and K-S tests? - ANS ✔✔0.05 where
-if p<.05, then reject null aka not normal
-if p>.05 you accept null and it is normal
What is Shapiro-Wilk test? - ANS ✔✔test for normality when sample size is less than 50
What is Kolmogorov-Smirnov (K-S) Test? - ANS ✔✔test for normality when sample size is greater
than or equal to 50
Nominal
1. Central Tendency
2.Measure of dispersion
3. Bar Type - ANS ✔✔1. Mode
2. None
3. Pie chart or Bar graph
Ordinal
1. Central Tendency
2.Measure of dispersion
3. Bar Type - ANS ✔✔1. Mode, Median
2. Range, IQR
