Standard Deviations
1=68%
2=95%
3=99.7%
Positive skew
Mean>median>mode
graph looks like bell curve is on left with tail on the right
Type 1 error
“You convicted an innocent man”

Analysis of Variance
Chi-Squared
Checks difference between 2 or more percentages or proportions of categorical outcomes (not mean values)
example: comparing the % of members of 3 different ethnic groups who have essential HTN
Pearson correlation coefficient
R is always between -1 and 1
closer to 1 then there is a perfect correlation
R squared is usually the value reported
