Probability distribution parameters

Normal distribution

What distribution is this parameter for:

Bell curve shape

Normal distribution

What distribution is this parameter for:

Continuous and used with measured data (distance, mass, area)

Discrete variable

Usually a whole number, counting is involved. It is possible to calculate a value

Normal distribution

What distribution is this parameter for:

No upper or lower limit to the values it can take

Binomial distribution

What distribution is this parameter for:

Only two outcomes

Binomial distribution

What distribution is this parameter for:

Probability of sucess (π or p) must stay the same

Binomial distribution

What distribution is this parameter for:

Number of trials (n) must be fixed with a lower limit of 0

Binomial distribution

What distribution is this parameter for:

Each occurence is independent of others

Meaning of π in binomial

Probability of success

Meaning of n in binomial

Number of trials

Triangular distribution

What distribution is this parameter for?

Maximum, minimum and mode given

Triangular distribution

What distribution is this parameter for?

Continuous

Triangular distribution

What distribution is this parameter for?

Takes shape of a triangle

Poisson distribution

What distribution is this parameter for?

Events are independent of one another

Poisson distribution

What distribution is this parameter for?

Events must not occur simultaneously

Poisson distribution

What distribution is this parameter for?

Events must occur unpredictably and randomly

Poisson distribution

What distribution is this parameter for?

The probability of an event occurring must be propostional to the size of the interval.
