A study was conducted, contrasting the number of miles that were driven, and the number of accidents that occurred. It listed the correlation coefficient as -1.3. What conclusion can you draw?

Any correlation coefficient below -1 indicates certainty, thus if you were to drive, you should avoid that area.

The correlation is a low negative, meaning there is an unclear relationship between these variables.

The correlation is a high negative, meaning there is a clear relationship between these variables.

None can be drawn, because that is an invalid number.
