How much high/low is the variance if a variable?

#1
Hello everyone,

How can you determine if a variable has a high variance or not?
The variance, the standard deviation and the coefficient of variation can take all non negative values. Is a variance of 20 high or low?

Thanks for you insights,
Ale

Is $1000 a lot of money? It depends on the context. If you're grocery shopping then yes. If you're talking about corporate expense accounts... maybe it isn't that much.

It depends on context.
