SQL SELECT AVG question

I have a table full of course dates, instructors, courses and a series of 'scores' for a range of likert responses (1-5).

Ultimately I'm going to pass this view to a SQLDataSource in asp.net, but what would the view be on the Server side?

I want to be able to perform an AVG function off a user-inputted date range, where if the user selected 2/1/2008 as a start date and 6/1/2008 as an end date, the return would be avg scores for all the records in between (or inclusive of those dates).

Any input?

Thanks!

something like


SELECT AVG(YourField)
FROM Yourtable
WHERE datefield BETWEEN @StartDate AND DATEADD(dd,1,@Enddate)

For accuracy, you may need to use
SELECT AVG(YourField*1.0)
FROM Yourtable
WHERE datefield BETWEEN @StartDate AND DATEADD(dd,1,@Enddate)
