Question

discrete random variable, what is it

Answer 1

i understand the basic definitions but the book i am using does not give a clear mean of discrete or continuous random variable in stats

Answer 2

A (random) variable is a type of measurement
taken on the outcome of a random experiment.
A discrete random variable is one which may take on only a countable number of distinct values such as 0,1,2,3,4,........ Discrete random variables are usually (but not necessarily) counts. If a random variable can take only a finite number of distinct values, then it must be discrete. Examples of discrete random variables include the number of children in a family, the Friday night attendance at a cinema, the number of patients in a doctor's surgery, the number of defective light bulbs in a box of ten.
