300 people have voted between 1 and 5, and the average of the votes is 4.83
How can I figure out the power of one vote? I understand that the value will change, depending on the number of votes. To make it simpler, how can I easily figure out the value of the 301st vote? For example, if my 301st vote is a 1, 2, 3, 4 or 5 .. to easily figure out how much that will change my average.
I can figure it out, but think there must be a formula I can put together to make it quicker.
Right now I'm multiplying the # of votes I have by my current average (so 300 * 4.83) , then adding to it what my next vote would be (1, 2, 3, 4 or 5) , then dividing the result by 301. Is that the easiest way to do it?
It would be nice to put together a formula where i can input the # of votes (V), my current average (A) and the amount of my next vote (?) and get a result of my new average
