SQL combine AVG and RANK

Question

I have a query 
    VariableWastage
              AS ( SELECT   ID ,
                            SCRAPVAR ,
                            COUNT(RECCODE) AS [COUNT] ,
                            RANK() OVER ( PARTITION BY ID ORDER BY COUNT(RECCODE) DESC ) AS [RANK]
                   FROM     RECIPE
                   WHERE    ITEMTYPE != 2
                            AND CAST(CAST(SCRAPVAR AS FLOAT) AS INT) != 0 -- excluding SCRAPVAR 0
    GROUP BY                ID ,
                            SCRAPVAR
                 )SELECT * FROM VariableWastage
which gives results
Where rows are highlighted how do I produce one row per item and get the AVG SCRAPVAR values between the duplicates?  So basically in result set I would expect to see all rows and 
    ABR001    1.025
    ABR002    1.025
    ABR003    1.025
where duplicated...
I just want to AVG the RANK output basically... Thanks!

try the following
VariableWastage
AS ( SELECT ID ,
SCRAPVAR ,
COUNT(RECCODE) AS [COUNT] ,
RANK() OVER ( PARTITION BY ID ORDER BY COUNT(RECCODE) DESC ) AS [RANK]
FROM RECIPE
WHERE ITEMTYPE != 2
AND CAST(CAST(SCRAPVAR AS FLOAT) AS INT) != 0 -- excluding SCRAPVAR 0
GROUP BY ID ,
SCRAPVAR
)SELECT ID, AVG(SCRAPVAR) as SCRAPVAR, COUNT,RANK FROM VariableWastage GROUP BY ID, COUNT,RANK
