Here's an approach that will list the most/least occurring number in a
range of cells, including any ties for most/least...

Assuming that A3 contains your label and A4:A12 contains your numbers...

In B3, enter: Freq

which is just a label

B4, copied down:

=IF(ISNA(MATCH(A4,$A$1:A1,0)),COUNTIF(A4:$A$12,A4) ,"")

In C3, enter: MF-Rank

which is just a label

C4, copied down:

=IF(N(B4),RANK(B4,$B$4:$B$12)+COUNTIF($B$4:B4,B4)-1,"")

In D3, enter: LF-Rank

which is just a label

D4, copied down:

=IF(N(B4),RANK(B4,$B$4:$B$12,1)+COUNTIF($B$4:B4,B4 )-1,"")

In E1, enter: 1

indicating you want the most frequent occurring number

E2:

=MAX(IF(B4:B12=INDEX(B4:B12,MATCH(E1,C4:C12,0)),C4 :C12))-E1

....confirmed with CONTROL+SHIFT+ENTER, not just ENTER.

In F1, enter: 1

indicating you want the most frequent occurring number

F2:

=MAX(IF(B4:B12=INDEX(B4:B12,MATCH(F1,D4:D12,0)),D4 :D12))-F1

....confirmed with CONTROL+SHIFT+ENTER, not just ENTER.

In E3, enter: Most Freq

which is just a label

E4, copied down:

=IF(ROWS(E$4:E4)<=E$1+E$2,INDEX($A$4:$A$12,MATCH(R OWS(E$4:E4),C$4:C$12,0)
),"")

In F3, enter: Least Freq

which is just a label

F4, copied down:

=IF(ROWS(F$4:F4)<=F$1+F$2,INDEX($A$4:$A$12,MATCH(R OWS(F$4:F4),D$4:D$12,0)
),"")

Hope this helps!

Hi, I would like to find out what type of formula that I can use to find
the least occurrence number in a column of numbers.

As I know I can use =mode() to find out the most appear number (the
number that come out the most) but I don’t know the formula for the
least appear number and the average appearing number.

Can someone help, thanks.
