Formula to find highest unique values in a range

[SimonGeoghegan]

Hi All,

I have a range of risks with risk scores between 1-25

("F2:F2460"), and ​

details about each of these risks within the range ("E2:E2460")

I need to provide a list which will return the top 'X' amount of risks depending on what the risk scores are. I need to show a minimum of 5, however if there are further risks which score the same as the 5th highest risk, they would also show, so I could have maybe 12,13,14 etc. that I need to display.

I have a hospital name in Cell H1.

I have a formula in Cell I1 which identifies how many instances of the highest risk score there are, for the hospital in H1.

[FONT=Verdana]=SUM(IF(Risks!$A2:$A2460=$H$1,IF(Risks!$F$2:$F$2460>=LARGE(IF(Risks!$A$2:$A$2460=$H$1,Risks!$F$2:$F$2460),MIN(5,COUNT(IF(Risks!$A$2:$A$2460=$H$1,Risks!$F$2:$F$2460)))),1)))[/FONT]

I then have a formula in Cells I2:I6 which tells me what the score is:

[FONT=Verdana]=IF(ROWS($I$2:I2)>$I$1,"",LARGE(IF(Risks!$A$2:$A$2460=$H$1,Risks!$F$2:$F$2460),ROWS($I$2:I2)))[/FONT]

And then a code in H2:H6 to give me the details:

[FONT=Verdana]=IF($I2="","",INDEX(Risks!$L$2:$L$2460,SMALL(IF(Risks!$A$2:$A$2460=$H$1,IF(Risks!$F$2:$F$2460=$I2,ROW(Risks!$A$2:$A$2460)-ROW($A$2)+1)),COUNTIFS($I$2:I2,I2))))[/FONT]

Is anybody able to point me in the right direction at all as to whether this can be achieved? I'm assuming it can, I just cannot think how to go about it!

Thanks in advance of any help!

Simon

Simon,

I think I'm onboard and it looks like you almost have it but shouldn't that final H2:H6 (which should probably be H2:H99 to catch duplicates of the last risk score)
INDEX(Risks!$L$2:$L$2460

...actually be...
INDEX(Risks!$E$2:$E$2460

	A	B	C	D	E	F	G	H	I
Hospital	Risk	St Elsewhere
St Elsewhere	Poisoning from Hospital meal	Risk 8
St Elsewhere	Surgeon can't tell Left from Right	Poisoning from Hospital meal
St Elsewhere	Stub toe on bed	Hospital Bill gives heart attack
St Elsewhere	Hospital Bill gives heart attack	Risk 6
St Elsewhere	Risk 5	Risk 7
St Elsewhere	Risk 6	Risk 24
St Elsewhere	Risk 7	Risk 26
St Elsewhere	Risk 8	Risk 27
St Elsewhere	Risk 9
St Elsewhere	Risk 10

Personally I'd use AGGREGATE to avoid the array formulae but you're so close it's probably not worth the surgery.

Thanks for this Toadstool, works perfectly now!

Appreciate your help and nice to know that I wasn't too far away from what I wanted to achieve!

You're welcome!

...and I trust my test data for column E risk descriptions is nowhere near the actual data
