A way you might estimate the benefits from a training program designed to teach employees how to use the WWW to monitor stock prices would be to use the time series evaluation design. With the time series evaluation design is used to collect outcomes at periodic intervals pre and post training. This evaluation design will help employees monitor how they are managing their stocks and make it easier to see what is happening with the use of graphs before and after training. Employees will be able to see when their stock choices are going up and when they are going down and will be able to discuss what they did in comparison groups.
