Once you create an index score, the calculation of counts can get really confusing. Let's start with an example:


We have 3 respondents:


respondent idscale1scale2
indexweight
11
10,75
22221,5
3322,50,75


UNWEIGHTED:

Once you calculate the mean of the index score, you will get a final result of 1,8 based on 3 respondents (base size). 


However, once you calculate a count it will just give you the result of all 1, 2, and 3's given:



123
Count131


This calculation is based on a total count of 5 (1+3+1 = 5, which is the base size)


And, once you calculate a percentage share it will just give you the result of all 1, 2, and 3's given:



123
percentage share of index20% (count =1)60% (count =3)20%  (count =1)

This calculation is based on a total count of 5 (base size is 5) too.


WEIGHTED:


Once you calculate the mean of the index score, you will get a final result of 1,88 based on 3 respondents (base size). 


However, once you calculate a count it will just give you the result of all 1, 2, and 3's given:



123
Count0,75
3,750,75


This calculation is based on a total count of 5 (0,75+3,75+0,75 = 5, which is the base size)


And, once you calculate a percentage share it will just give you the result of all 1, 2, and 3's given:



123
percentage share of index14,3 % (count =1) 71,4 % (count =3)14,3 %  (count =1)

This calculation is based on a total count of 5 (base size is 5) too.
