M1 Flashcards
branch of applied mathematics that involves the collection, description, analysis, and inference of conclusions from QUANTITATIVE DATA
STATISTIC
means possibility; deals with the occurrence of a random event.
PROBABILITY
value is expressed from zero to one
PROBABILITY
___ is used to show possible outcomes; S{ }
SAMPLE SPACE
the subset of sample space
EVENT
the number of ways an event can occur; subset of sample space
PROBABILITY OF AN EVENT
what is P { }
PROBABILITY OF AN EVENT
____ is the arrangement of every possible outcome of an experiment
SAMPLE SPACE
function that associates a real number with each element in the sample space; variable whose value are determined by chance; A NUMERICAL OUTCOME
RANDOM VARIABLE
can take on finite number of distinct values
DISCRETE RANDOM VARIABLE
uncountable number of potential values, regularly measurable amounts
CONTINUOUS RANDOM VARIABLE
term if X is a discrete random variable?
PROBABILITY MASS FUNCTION (PMF)
PMF 3 FORMS
TABULAR, FORMULA, GRAPHICAL
property where the probability of each value of the random variable is non negative
NON NEGATIVE PROPERTY
what property is 0 ≤ P(x) ≤ 1
NON NEGATIVE PROPERTY
a property where the sum of values of PMF of x cant exceed/must be equal to 1
NORMING PROPERTY
∑ P(X) = 1
NORMING PROPERTY
what property involves standardizing variables to have a common scale or distribution
NORMING PROPERTY
what random variable that values are exact and can be represented by non negative whole numbers
DISCRETE RANDOM VARIABLE
what random variable are often result of measurement, can be represented by fractions, decimals, and non negative whole numbers
CONTINUOUS RANDOM VARIABLE
