# Statistics help?

Someone says, “There is a strong positive correlation between the number of firefighters at a fire and the amount of damage the fire does. So sending lots of firefighters just causes more damage.

Identify possible lurking variables. (Select all that apply.)

damage caused by fire

distance of firehouse from fire

seriousness of fire

experience of firefighters

number of firefighters

The statement is TRUE, but the conclusion is NOT.

‘Lurking Variables’ would include:

damage caused by fire

distance of firehouse from fire

number of firefighters

It is true there is a positive correlation between the number of firefighters at the fire and the damage done. The final statement should read “So sending ‘less’ firefighters causes more damage!
