Help with AVG

Hi,

How can I get the average/sum of a column in this query.  The query has about 30 records in it, here is the SQL I'm using to get the data out.

SELECT q.SurveyID, q.questionID, q.QuestionScore, q.QuestionName
FROM Questions q


surveyID | questionID | QuestionScore | QuestionName

28323          2                     45                       Do you like food?
34852          2                     88                       Do you like food?
38052          2                     14                       Do you like food?
28323          55                   15                       Do you like milk?
34852          55                   28                       Do you like milk?
38052          55                   48                       Do you like milk?


I want to return one row  with an average score here for each questionID.  So I'm trying to get just two rows back.

How can I modify my query to do this?

Thanks...

I think jogos forgot to remove D from the SELECT list. it should be:

SELECT q.questionID, AVG(q.QuestionScore)
FROM Questions q
group by  q.questionID

It will return just 2 rows

SELECT questionID,QuestionName, [28323], [34852] ,[38052]
FROM (select questionID,SurveyID,QuestionScore,QuestionName
from Questions) as sourcetable
pivot
(
avg(q.QuestionScore) for SurveyID in (28323,34852,38052)
) as pvt
orderby pvt.questionID
