Discrete Uniform Random Variables Flashcards
1
Q
what does it mean for a variable to be uniform
A
it is equally likely to take any number in the set
2
Q
what is the expected value of a constant uniform random variable
A
the constant itself
3
Q
what is the variance of ax + b
a and b are constants
A
a^2 Var(x)
4
Q
as the number of variables in a uniform set gets larger, how does the variance change
A
variance gets larger
