What is a random variable?

A random variable is a function that assigns unique numerical values to all possible outcomes of a random experiment. A real valued function defined on a sample space of an experiment is also called random variable.


What is the Possible result of a probability event called?

It Is Called An Outcome :) ( YOur Welcome)


A numerical value calculated for a sample is called a?

A numerical value calculated for a sample is called a descriptive statistic.


What is the name of the variable plotted on the x axis?

the variable on the x axis is called the independent variable. the y axis is called the dependant variable


What is meant by probability distribution?

I will give first the non-mathematical definition as given by Triola in Elementary Statistics: A random variable is a variable typicaly represented by x that has a a single numerical value, determined by chance for each outcome of a procedure. A probability distribution is a graph, table or formula that gives the probabability for each value of the random variable. A mathematical definition given by DeGroot in "Probability and Statistics" A real valued function that is defined in space S is called a random variable. For each random variable X and each set A of real numbers, we could calculate the probabilities. The collection of all of these probabilities is the distribution of X. Triola gets accross the idea of a collection as a table, graph or formula. Further to the definition is the types of distributions- discrete or continuous. Some well know distribution are the normal distribution, exponential, binomial, uniform, triangular and Poisson.
