I have a group of 10 products, their rate of sale varies over time. At one point, a factor was added to 5 of the 10 products to see if their rate of sale increased relative to the other 5. Because sales vary over time, I think it's necessary to compare the two groups mean sales in a time period before the factor was introduced and after the factor was introduced. I can do this just fine, but what exactly would my test statistic be so I can write a report with evidence of a change. Attached is some example data..so how do I find evidence the factor has some effect..

Many thanks
