If i have a series of 10 objects with rating from 1 to 10. Then how can i calculate overall rating?
For example if i have a list like this:
Entertainment - 8/10 Fun - 9/10 Comedy - 6/10 Dance - 8/10
and so on... Like this 10 objects. Tell me how to calculate the overall rating for 10.
Overall - ?/10
I am very weak in maths. I was told by someone to add the total and if I got 83 as the answer, then the overall rating will be 8.3/10. Is this correct?
I am doing this for my PHP website. So if someone knows how to write a query for this, that would be very helpful for me.
