Statistics and probability terms reviewer

It is a numerical quantity that is assigned to the outcome of an experiment.

• Random Variable

• Discrete Random Variable

• Continuous Random Variable

These are random variables that can take the values of the whole numbers or set of natural numbers.

• Random Variable

• Discrete Random Variable

• Continuous Random Variable

"This is the result of rolling a die" is what type of random variable

• Random Variable

• Discrete Random Variable

• Continuous Random Variable

• This random variable can take any values within the given intervals.

• Random Variable

• Discrete Random Variable

• Continuous Random Variable

The length of electrical wires is an example of what random variable.

• Continuous Random Variable

• Discrete Random Variable

• Random Variable

A distribution that deals with all the possible values and likelihoods that a random variable can take within a given range.

• Probability Distribution

• Statistics and probability

• Probability dispersion

• It is the central or average of its corresponding probability mass function.

• mean

• median

• mode

• standard deviation

What is the correct formula for mean

• µ = E(X) = ∑xP(x)

• µ = ∑xP(x), = E(X),^2

• µ = ∑xP(x) = ∑xP(x),

• µ = E(X) = E(X)^2

These are the two values that describe how scattered or spread out the scores or items are from the mean value of random variable or distribution.

• Variance & Standard deviation

• Mean & Standard deviation

• Mean & Variance

This is a table providing the area covered between the mean and a z-score

• Z- table

• X- table
