 |
|
If I have a spreadsheet like:
B|C
Malcolm|30
Thomas|40
Iain|30
Stuart|50
Robert|30
Matthew|20
And I want the rankings to go 1,2,3,4,5,6 rather than 1,2,3,3,3,6 - is there a way to do it? |

You can introduce a "fudge factor".
Assuming all scores are integer. In cell D1, enter the formula =C1+ROW()/1000000, copy down, and use that for ranking. This will introduce minute and unique variations, thus reliably resolving ties.
Note that if your score figures exceed 8 digits, the limitations of Calc's floating point arithmetic will introduce rounding errors to my formula, possibly cancelling out the "fudge". |

| Thanks - whilst that makes column D have unique figures, it still shows the rankings (which I have in column A) as effectively equal - ideally I would like it to show 1, 2, 3, 4, 5, 6. |

Can you post the formula you use for column A? |

=RANK(C1;$C$1:$C$20) is what I have at the moment. |

Change your ranking formula to use column D:
=RANK(D1;$D$1:$D$20) |
