Mode, median, mean pros + cons

A u B

That either A or B or both occur

P(B/A)

Prob that b will occur given that A as already happened

P(AnB)=0

Mutually exclusive events

Coding

P=x-a/b. Q=y-c/d

Regression line equation

Y=a+bx

Why use coding

To simplify calculations

Interpolation and extrapolation

Interpolation - when the x value is in range so a reliable estimate


Extrapolation- when the x value is out of range so not a reliable estimate

Discrete random variable

Variance

Measure of the spread relative to the mean

Discrete uniform equations only

Normal distribution equation

Variance equation

Mathematical models pros and cons

What does and doesn't effect coding

Stem and leaf pros and cons

What tells you how skewed the data is

Quota sampling

Standard deviation

Ncr

Normal distribution qualities

Percentages for nd
