how to compute rating score based on votes

284 Views Asked by At

What is the formula to compute the rating score based on votes. Imagine each person can vote between 1 to 10. Now I have 20 votes from people. the results look like this:

[1 1 2 5 0 1 0 0 10 0]

Meaning that we have 1 vote for (1), 1 vote for (2), 2 votes for (3), ..., and 10 votes for 9, and 0 vote for (10). Now I want to compute a final score, like e.g. 8.75 (this is just a random score). Is there any formula to do that? The score should be something between 0 to 10. I think my post is kinda similar to this Post. But i cannot understand how to use the formula there :(

Thanks

If I understand your question, you want to find the average score.

$1\cdot1+2\cdot1+3\cdot2+4\cdot5+5\cdot0+6\cdot1+7\cdot0+8\cdot0+9\cdot10+10\cdot0=125 $

Then, divide it by the number of participants, $125/20=6.25$, which is the average score.
