Lesson 1 | Random Variable (MA'AM IVY) Flashcards
is a variable whose possible values are outcomes of a random process or experiment.
random variable
is a set of whose elements are the numbers assigned to the outcomes of an experiment.
random variable
It is usually denoted by uppercase letters such as X whose elements are denoted by lowercase letters
random variable
can only take finite (countable) number of distinct values.
discrete random variable
The values are exact and can be represented by nonnegative whole numbers.
discrete random variable
can assume an infinite number of values in an interval between two specific values
A continuous random variable
This means they can assume values that can be represented not only by nonnegative whole numbers but also by fractions and decimals.
A continuous random variable
These values are often the results of measurement.
A continuous random variable
When outcomes in an experiment are mapped to their corresponding probabilities by means of table of values, graphs or equations, a ____ is formed
Probability Distribution
it can be represented as function, table or histogram.
Probability Distribution
is a table showing all the possible values of a discrete random variable together with their corresponding with their probabilities.
discrete probability distribution
The probability distribution of a discrete random variable. Can be represent through function, table or histogram.
PROBABILITY MASS FUNCTION
provides a measure of the center of distribution of the variables.
