Employee retention is a major concern for many companies. A survey of Americans asked how long they have worked for the current employer (Bureau Labor Statistics website). Consider the following example of sample data of 2,000 college graduates who graduated five years ago.

1 | 506 |
2 | 390 |
3 | 310 |
4 | 218 |
5 | 576 |

Each restaurant received a 3-point scale on typical meal price (1 least expensive to 3 most expensive) and quality (1 lowest quality to 3 greatest quality).

Forty-two of the restaurants received a rating of 1 on quality and 1 on meal price, 39 of the restaurants received a rating of 1 on quality and 2 on meal price, and so on. Forty-eight of the restaurants received the highest rating of 3 on both quality and meal price.
