Counting Observations by day and then Average by Month

RobertNYC — Mon, 07 Apr 2014 23:03:27 GMT

Hi all--

I need to calculate the average touches by month. Below I have a column Touch_ID which has all unique values, so each row represents a "Touch" and date value for each touch. Example:

Touches_ID	Date
5648	1/20/2014
448961	1/20/2014
45645	1/20/2014
458750	1/20/2014
457867	1/20/2014
56456456	1/21/2014
4564564	1/21/2014
25879	1/21/2014
42545674	1/21/2014
4545872	1/21/2014
45875	1/22/2014
6968	1/22/2014
32548	1/22/2014
121558	1/22/2014
5456	1/23/2014
899	1/23/2014
45555	1/23/2014
7894	1/23/2014
6968	1/23/2014
44556	1/23/2014
8789943	1/23/2014

I need to calculate the average touches by month. So, I need to get a count of total touched for each day and then calculate the monthly average.

Any assistance is greatly appreciated.

My brain may be fried...end of day...but why do you need the daily totals? is the "monthly" average a daily average for the month?

proc sql;

create table new as select *,count(touches_id) as touches, month(date) as month from old group by date;

quit;

proc sort data=new nodupkey;

by date month touches;

run;

Now you can caluclate the average by using by variable as month.

Hope this solves your problem, If not please elobrate your question or give a sample out put with example for understanding with small values.
