Calculating and displaying Averages problem. Help please!
I am stuck on calculating an average using data I have uploaded within an Excel file. I have tried achieving this both from within Zoho Reports and also by adding new data within Excel to make it easier for Reports to calculate.
Within my table I have one column named "Consultant" one named "Date" and the other named "Placement Count"
Each time a row of data is added the name of the Consultant (from a drop down list in Excel) together with the date of the placement and the Placement Count which is always either 1 or 0.5.
So for example, a selection of data may look like the following:
John Smith 01/01/18 1.0
John Smith 10/01/18 1.0
John Smith 24/02/18 0.5
John Smith 18/03/18 1.0
At a quick glance you can see that John Smith's total placement count in January 2018 is 2 and John Smith's total placement count in February 2018 is 0.5 and John Smith's total placement count in March 2018 is 1. His total placement count for the whole three month period is 3.5. (2 in January + 0.5 in February + 1 in March)
Showing the total placement count on a monthly basis I have done quite easily in either a line chart or table and this shows the ongoing monthly totals and correctly displays 2 for January, 0.5 for February and 1 for February
What I can't figure out is how to also show the averages in the way I want to display the averages.
For example, at the end of January the placement count was 2 and one month had passed in the year. 2 placements in 1 month is an average at that point in time of 2 per month (2/1)
When the second month of the year had passed, February, where the placement count was 0.5, the total placement count across the 2 months (January and February) is 2.5. 2.5 Placement in 2 months is now an average for the year to date of 1.25 per month (2.5/2)
When the 3rd month of the year had passed, March, where the placement count was 1, the total placement count across the 3 months (January, February and March) is 3.5. 3.5 in 3 months is now an average for the year to date of 1.17 per month (3.5/3)
By either adding extra data in my Excel spreadsheet and then using a formula in Reports on that data, or, with the existing Date, Consultant and Placement Count Fields, how can I show a running year to date average alongside also showing the placement count amount for each month and per consultant?
Thank you!
