I have a large spreadsheet with data in the following format:

Product Price Sales
A $1.00 10
B $2.00 9
C $3.00 8
D $4.00 7
E $5.00 6
F $6.00 5
G $7.00 4
H $8.00 3
I $9.00 2
J $10.00 1

And I am trying to analyse the relationship between price and sales.

I have tried to use a pivot table with the product as the data and then
price and sales as the rows and columns, but then I am getting stuck with
changing the field settings.

Using the above example, Ideally I would like to be able to group the prices
into price breaks of 2.00, and then calculate the total sales for each group.

Is a pivot table the best way to do this and is there any online training
that would cover it?

Or is there other tools within Excel (but not programming or vb) that can
help with calculating the correlation between the price and sales?

THanks
