Distribution Types
A finite number of values are equally likely to be observed
What is a Uniform distribution?
f(t) = ve-vt
What is the Exponential distribution?
Can take only a finite number of values
What is a discrete variable?
Probability distribution of a continuous variable
What is a PDF?
The most probable value of random variable x
What is the mode?
The number of event occurrences during a specified period of time or space
What is the Poisson distribution?
What is the Normal distribution?
The probability that a random variable X is less than or equal to a specific number, x
What is a CDF?
The value of this integral is 1
CDF is 50%, F(x) = 0.5
What is the median?
The probability of success is known and the trial can result in only one of two possible outcomes
What is the Bernoulli distribution?
1/(b-a)
What is the Uniform distribution with continuous variables?
This is the probability distribution for a discrete variable
What is a PMF?
What is P(X=any value)?
mean = median = mode
The variance is defined as np(1-p)
What is the Binomial distribution?
1/n
What is the Uniform discrete distribution?
The derivative of a CDF
what is a pdf?
What is a CDF?
The direction of the tail is to the right
What is positive skew?
Describes the recurrence time of a Poisson process
What is the Exponential distribution?
e-vt(vt)x/x!
What is discrete Poisson distribution?
A variable whose measured value can change from one replicate of an experiment to the next
What is a random variable?
A PDF is _________ probability?
The peak of the distribution is higher and narrower than normal
What is Leptokurtic?
