Continuous Uniform Distribution Flashcards
How do you find the probability density function/ ‘f(x)’ for Continuous Uniform Distribution?
1 / (b-a)
How do you find the cumulative density function / ‘F(x)’ for Continuous Uniform Distribution?
- Integrate like you would for chapter 3
2. x-a / b-a
How do you find E(X) for continuous uniform distribution?
1
—- (a + b)
2
How do you find Var(X) for continuous uniform distribution?
1
—- (b - a) ^2
12
How do you find P(X
(X-the limit) * pdf
Aka find the area of the rectangle
Who do you find P(X=x) for a continuous uniform distribution?
It’s 0
It’ll always be zero for continuous
How do you work out P(A
(B-A) multiplied by pdf
How do you work out the UQ and LQ for continuous uniform distribution?
Find a quarter of the range of limits:
LQ- Go a quarter away from the lower limit, and multiply by the PDF
UQ- Go a quarter from the upper limit, and multiply by the PDF
IQR- UQ-LQ
What is meant by defining the pdf? (UUUI)
Integrate
What is the Proof for E(X) and Var (X) for continuous uniform distribution?
