ok so I'm in the office and OMG GCSE Maths is so long ago
I have this data -
1 6
2
3 39
4 72
5 36
it's for students rating something 1-5, so the first column is what they voted and the second column is the total number of students who voted for each.
How the feck do I work out the average number voted on this particular question?
Answers ASAP PLEASE!
