Sample Space

gives set to all outcomes

TERM 2

odds in favor of event A

DEFINITION 2

P(A) | P(A)

TERM 3

mutually exclusive events

DEFINITION 3

when 2 events have no sample points in common

TERM 4

addition rule

DEFINITION 4

P(A or B) = P(A) + P(B) - P(A and B)

TERM 5

Probability distribution

DEFINITION 5

equation or table that links the outcome of an experiment

with the probability of occurrence

Central Limit Theorem

states that the sampling distribution of the mean will be

normal or nearly normal if the sample size is large enough

TERM 7

Statistic

DEFINITION 7

numerical measurement that describes characteristics of a

sample

TERM 8

Parameter

DEFINITION 8

numerical measurement that describes characteristics of a

population

TERM 9

DEFINITION 9

sub collection from population in which you are observing

TERM 10

census

DEFINITION 10

data collected from entire population

Null hypothesis

value of population parameter is equal to some claimed

value

TERM 17

type 1 error

DEFINITION 17

reject null hypothesis when true

TERM 18

When to Use T distribution:

DEFINITION 18

when mu isnt known

TERM 19

R

DEFINITION 19

linear correlation coefficient for the sample data

TERM 20

r

DEFINITION 20

square of R and coefficient determination variation in 'Y'' that

us explained by linear relation to 'X"

Correlation

exists between 2 variables when the values of the one

variable are somehow associated with the values of the other
