After publishing a tip on the most frequent item in a list
I decided to build a model based on frequency.
The first formula used is the aforementioned most frequent item formila.
where ListRange = A2:A16
Then, another formula was needed to return subsequent frequent items,
entered into cell E3 and copied down.
The formula to return the number for each item was entered in F2 and copied down.
The amount spent on each transaction type was calculated the formula placed in G2 and copied down.
where Total = B2:B16
Finally, information can be used columns F & G to make a formula that will return the average for each transaction type.
The finished table is shown in the following figure.
