sql group by calculated column

Hi, how can I group by a calculated column?  I am trying to do what is below and it is not working.

select
 case  when StartingIv >= 0 and StartingIv < 0.1 then '0-0.1'
 when StartingIv >= 0.1 and StartingIv < 0.2 then '0.1-0.2'
 when StartingIv >= 0.2 and StartingIv < 0.3 then '0.2-0.3'
 when StartingIv >= 0.3 and StartingIv < 0.4 then '0.3-0.4'
 when StartingIv >= 0.4 and StartingIv < 0.5 then '0.4-0.5'
 when StartingIv >= 0.5 and StartingIv < 0.6 then '0.5-0.6'
 when StartingIv >= 0.6 and StartingIv < 0.7 then '0.6-0.7'
 when StartingIv >= 0.7 and StartingIv < 0.8 then '0.7-0.8'
 when StartingIv >= 0.8 and StartingIv < 0.9 then '0.8-0.9'
 when StartingIv >= 0.9 and StartingIv < 1 then '0.9-1'
 when StartingIv >= 1 and StartingIv < 1.1 then '1-1.1'
 else 'ELSE'
 end as IvRange
