I cant post the table. Because I'm on my phone >.<

anonymous · Answer

Average = (Sum of all the numbers in the list) / (how many numbers)

That should help.

I just tried posting the table. It's got frequency of ages

anonymous · Answer

Frequency just means how many times that age appears. So if the frequency of age 3 is 2, there are 2 children age 3. Or if the frequency of age 7 is 9, there are 9 kids that are 7 years old. 

Add up the age of everyone in the class, then divide by the number of kids. That's the average age.

Ah thank you very much!! I appreciate that :) the frequency part caught me off guard. I hadn't worked too much with tabulated data before >.
