probability

A number from 0 to 1 that shows the

likelihood that an event will happen.

ratio

A ratio shows the relative sizes of two or more values.


1:3 (for every one boy there are 3 girls)1/4 are boys and 3/4 are girls0.25 are boys (by dividing 1 by 4)25% are boys (0.25 as a percentage)

outcome

The result of something.

Head and tails are two outcomes from flipping a coin.


frequency

The number of times a value occurs in a set of data.


frequency graph

A graph showing how often each value in a data

set occurs.By J. Scheumann and C. Sorenson 2011

frequency table

A chart on which data is tallied to find the

frequency of given events or values.


relative frequency

All the Relative Frequencies add up to 1 (except for any rounding

error).By J. Scheumann and C. Sorenson 2011

predict

Outcomes are the results of an experiment or trial. Using

outcomes, it is possible to make predictions. A prediction is a guess about what will happen.

likely/unlikely

In mathematics, likely is having a greater than 50 % chance of

happening. Unlikely is have less than 50% chance of happening.

In mathematics, if an outcome is certain, the

chances are 100%.

event

A happening or

occurrence.By J. Scheumann and C. Sorenson 2011

random sampling

Taking a sampling from the population in a

manner that allows all members the same chance

of being included.By J. Scheumann and C. Sorenson 2011

theoretical

The probability based on known facts or

characteristics. This is what should happen in an

experiment. By J. Scheumann and C. Sorenson 2011

experimental

The probability based on the outcomes obtained by

conducting an experiment.


sample

A subset of a population used to

represent the whole population.


combinations

Combinations pop up in ordinary life all the time. When you need to find out

all the possible combinations of something, an organized list is the way to go.
