Week 4B Flashcards
Continuous Random Variable
a variable that can assume any
value on a continuum (can assume an infinite number of values)
-These can potentially take on any value, depending only on the ability to measure accurately (e.g. lab values, time required to complete a task wight, BMI, viral load)
Probability distributions
Discrete Probability Distributions
***Binomial
Poisson
Hypergeometric
Probability distributions
Continuous Prob. Distributions
***Normal
Uniform
Exponential
Normal Distribution
Shape:
Bell-shaped - symmetrical
Mean, median, and mode are equal
Central location is determined by the mean, μ
* Spread is determined by the standard
deviation, σ
* The random variable X has an infinite
theoretical range: + to
Translation to the standard distribution
Any normal distribution (with any mean and standard deviation
combination) can be transformed into the standardized
normal distribution (Z)
