Hello,
I'm really hoping someone can help me with standard deviation for grouped data. I have read the formula and tried several problems but it just doesn't click.
If I need to calculate a standard deviation of the number of cars in households, what is the correct way to do it?
0 cars - 1635 households
1 car - 2800 households
2 cars - 2410 households
Your help would be much appreciated!
