Set of experimental or theoretical values of a given statistical or random variable.

### Examples

**Experiment 1**

We are randomly drawing marbles one by one from a bag that we don’t know anything about.

After 100 draws, the results are: 12 white marbles, 35 black marbles, 8 red marbles and 45 blue marbles.

The distribution of the values – in this case, *experimental* – of the random variable “drawing a marble from the bag” is: {white, black, red, and blue}.

**Experiment 2
**We are rolling an honest die with 6 faces numbered 1 to 6 and recording the result obtained.

After 10 rolls, here are the results: 1 was rolled 2 times, 3 was rolled 2 times, 5 was rolled 2 times and 6 was rolled 4 times.

The distribution of values – in this case, *theoretical* – of the random variable “*rolling a die and recording the result*” is: {1, 2, 3, 4, 5, 6}.
