The following table lists all possible samples of size 2, their means () and their probabilities.

Sample | 0,0 | 0,1 | 0,5 | 1,0 | 1,1 | 1,5 | 5,0 | 5,1 | 5,5 |

0 | .5 | 2.5 | .5 | 1 | 3 | 2.5 | 3 | 5 | |

P | 1/9 | 1/9 | 1/9 | 1/9 | 1/9 | 1/9 | 1/9 | 1/9 | 1/9 |

This gives the following sampling distribution:

0 | .5 | 1 | 2.5 | 3 | 5 | |

P( = ) | 1/9 | 2/9 | 1/9 | 2/9 | 2/9 | 1/9 |
