Hi, 

I am interested in showing that the respondent´s assessments on one item of my set are more heterogeneous than for the others. 

Im using stata 12 

I have 6 items describing how important respondents found certain issues to be on a scale of 1 "not important" to 4 "very important".
Looking at the data and the frequency table, I have the feeling that the agreement on one item is much less than on the other. 
Else I would say there is more divergence in the answers, which is roughly shown by the summary tables, although I should not really 
look at means and standard deviations of ordinal variables.


    Variable |       Obs        Mean    Std. Dev.       Min        Max
-------------+--------------------------------------------------------
       c0101 |       429     3.69697    .5690746          1          4
       c0102 |       425    3.207059    .8872509          1          4
       c0103 |       428    3.429907    .7385301          1          4
       c0104 |       411    2.474453    1.010291          1          4
       c0105 |       430    3.430233    .6885798          1          4
       c0106 |       430    3.590698     .665435          1          4

I would believe that c0104 is more controversial issues than c0101.
I yet have not found a way to express my above given statement in a meaningful statistical way. Is there a way to test my statement?


Best regards

Max
