A variable whose possible values are determined by chance. |
Random Variable |
|
2 TYPES OF RANDOM VARIABLE |
DISCRETE RANDOM VARIABLE CONTINUOUS RANDOM VARIABLE |
|
can only take a finite ( countable ) number of distinct values. The values are exact and can be represented by nonnegative whole numbers. |
DISCRETE RANDOM VARIABLE |
|
Assume an infinite number of values in an interval between two specific values. These values are often results of measurement. |
CONTINUOUS RANDOM VARIABLE |
|
A listing of all ;possible values of a discrete random variable along with their corresponding probabilities . This can be presented in tabular, graphical or formula form. |
DISCRETE PROBABILITY DISTRIBUTION |
|
Possible outcome |
Sample space |
|
describes the probability of each specific value in a random variable. |
PROBABILITY DISTRIBUTION |
|
The probability distribution of a discrete random variable. |
PROBABILITY MASS FUNCTION |
|
The average outcomes |
Expected value of x |
|
Also called the expected value of x |
Mean of discrete random variable X |
|
is the average of the outcomes that likely to obtained if the trials are repeatedly over and over again. |
Expected value of x |
