Hello,(adsbygoogle = window.adsbygoogle || []).push({});

To anyone who knows a lot about calculating averages:

I NEED HELP WITH:

I need some help with some statistical calculations regarding how much time is spent on classes, subjects, and homework at school. I am trying to calculate the mean average from some raw data and what puzzles me is that when I use two different ways to calculate the answer I get two different results.

I think both of my methods are correct so I'm guessing that the reason for the discrepancy is because I used slightly different ways to derive my answer. However, I can't shake the feeling that the answers should be identical and I don't really understand why they are not.

I WOULD LIKE TO KNOW / NEED HELP WITH:

Which method is correct? Are both methods correct? Is one more accurate then the other, and if so, why? And if one method is wrong, then why?

Please see attached PDF file for all my calculations and the specific problem I'm having.

Thank you in advance for anyone who helps. I'm stumped atm. x3
