We can apply Chebyshev's theorem to any distribution irrespective of its shape. We can, however, apply the empirical rule if the shape of the distribution is bell shaped.

Question 1 options:

True

False

A binomial distribution is a distribution that has only two outcomes—success or failure.

An example could be win/lose in a game.

Question 2 options:

True

False

In order to apply the formulas for mean and standard deviation, we must first determine if we have raw data, a probability distribution or a binomial distribution. There are 3 different formulas for the mean and each of these 3 types of data requires a unique formula.

Question 3 options:

True

False

There are some data sets for which it is not appropriate to calculate a mean. Examples are nominal or ordinal data OR data sets that do not meet the criteria for applying formulas for raw data or a probability distribution.

Question 4 options:

True

False

The maximum USUAL value is calculated by the following formula. 

Mean + 2(standard deviation). 

Question 5 options:

True

False
