I am studying for Pre-GCSE maths paper and I need to learn Mode, Mean, Medium, Range and PTask. I have learnt all of them except the mode, infact I have learnt mode but I have heard two versions of it.
Say I had a mode array of: 1 5 6 7 0 0 3 4 0 5
Version 1:
1 + 5 + 6 + 7 + 3 + 4 + 5 = 31
31 divided by element count, so 31 divided by 10 = 3
I would write on my paper: 3
Version 2
1 + 5 + 6 + 7 + 3 + 4 + 5 = 31
31 divided by element count, so 31 divided by 10 = 3
Then some say I have to write it like below, I'm not sure how they get that number.
I would write on my paper: 3.1
Which version should I actually be writing on my paper? Will I get a mark for either? any help would be appreciated.
