*****   SIMS 2000:  Top/Bottom 2 Boxes & 3 Boxes - Basic Usage Notes   *****

  Purpose:
  --------

   The Top/Bottom 2 Boxes & 3 Boxes Report summarizes the extreme observations for Hedonic Attributes.
   Market research studies often refer to positive and negative rating measures
   using the Top/Bottom 2 Boxes & 3 Boxes percentages as indicators of consumer acceptance.

   If you intend to use this report with your Hedonic Attributes, it is generally a good 
   idea to design your Questionnaire's Hedonic Attributes so that the return values assigned 
   to each Hedonic choice DESCEND from the top answer to the bottom answer.   The top answers 
   should be favorable (Like extremely, Like very much, etc.) while the bottom ones should 
   be unfavorable (Dislike extremely, Dislike very much, etc.).

   For Horizontal Hedonics, choices should DESCEND from the left answer to the right answer.
   The left answers should be favorable (Like extremely, Like very much, etc.) while the 
   right ones should be unfavorable (Dislike extremely, Dislike very much, etc.).

   The Top/Bottom 2 Boxes & 3 Boxes are commonly Ranked by the 'VISUAL' location of the Boxes, Top & Bottom.
           For Horizontal Hedonics,  Top 2 == Left 2  and  Bottom 2 == Right 2 

   The Top/Bottom 2 Boxes & 3 Boxes can also be Ranked by the Return 'VALUES' of the Boxes, High & Low.
           Top 2 == 2 Highest Return Values  and  Bottom 2 == 2 Lowest Return Values 

   If your Hedonic questions are already designed with Top/HighValue and Bottom/LowValue,
      the most common usage, then the report will produce same result with either rank option.

   Top/Bottom 3 Boxes follow same logic and notes.


   Here is an example:

      Using the scale below, how do you feel about the sample flavor?

      Like extremely 
      Like very much 
      Like slightly 
      Neither like nor dislike 
      Dislike slightly 
      Dislike very much 
      Dislike extremely 

        The values of each answer are assigned from 7 (Like Extremely)
            down to 1 (Dislike extremely).


   Your Report for Top 2 might look like this:

      Top 2 boxes
      Attribute		Sample 1		Sample 2		P-val	Sig

      Liking   		 9 (75%) 		 6 (50%)  		0.234	NS


      In this example Twelve respondents answered the question for each sample.
      Nine respondents (75%) selected either Like Extremely or Like very much 
      for Sample 1, while six (50%) selected either of those answers for Sample 2.


  Report Options:  
  ---------------
    Hedonic Attribute Selection.  By default, all Hedonic Attributes are included in report. 
      You have the option to select individual Hedonic Attributes, one, many, or all. 

    Include Statistics P-val && Significance - SAS Analysis
      This report option will include the superscripts, p-values, and significance levels
      as reported in normal Anova/(Duncan/LS) analysis for each of the hedonic attributes.

        SAS Analysis Specs:   (per B. Thomas Carr, M.S., Feb 2002) 
          Actual Attribute return data points are not exported to SAS, instead these actual
          values are compared with Top/Bottom 2 Values, and if inclusive then a data value
          of '100' is exported to SAS, otherwise a data value of '0' is exported to SAS.
          In other words, the SAS Data Sets, for each Hedonic question (X1-Xn),
            will always export either: 
                         a) 100,   b)0,   or  c).   ( . = null) 

          Top Two Boxes are defined as being the Top Two SEEN Boxes, Bottom is opposite. 


          Option: Use 'One-Way Model' Between Samples
              - Used in PROC GLM to calculate means and P-values based
                    on the Sample as the ONLY independent variable.
                    Otherwise the normal default independent variables are Judge and Sample (Two Variables).
              - When your Experimental Design is of the type n Samples Present 1, the One-Way
                    Model Between Samples may be an appropriate analysis option, especially
                    when there are different sets of respondents testing each sample.

                'One-Way Model'                          'Two-Way Model'
                 PROC GLM;                               PROC GLM;
                 CLASS SAMPLE;                           CLASS JUDGE SAMPLE;
                 MODEL X1-X10 = SAMPLE;                  MODEL X1-X10 = JUDGE SAMPLE;
                 MEANS SAMPLE / DUNCAN ALPHA = 0.0500;   MEANS SAMPLE / DUNCAN ALPHA = 0.0500;


    Include Hedonic Attribute Details
      This report option will include, for every Hedonic Attribute on your report,
      details about the Hedonic's  a) choice labels  b) Seen Order  c) actual return values
      Selecting this report option could add a few additional pages to your report.

    Include SAS Data Set Details
      This report option will include ALL the Hedonics SAS Data set Details, Actual and SAS.
      Selecting this report option could add a few additional pages to your report.

    Drop Counts, Show Only Percentages
      This report option will drop the count of panelists (n) who answered within the Top/Bottom 2 Boxes
      for each Attribute/Sample, and only display the Percentages of panelists.

    Include Means Rows
      Will include rows of mean score calculations for each Attribute/Sample.
      This optional row will only appear in the final MS Word/Excel export.
          Include Stats Mean Separations, optionally you can combine the statistics 
            calculations from a previously performed statistical analysis.
            If this option is desired, please run statistical analysis prior to Top/Bottom 2 Boxes.


  Rounding Notes:  
  ---------------
    SIMS 2000 adheres to ASTM standards for Rounding Test Data. 

    ASTM E29-93a
      'Standard Practice for Using Significant Digits in Test Data
       to Determine Conformance with Specifications'.
     Clause 6.4 of E29 covers the rounding rules, which go beyond the 5/4 rule.

     Here is a brief summary: 
       - When the digit beyond the one you want to keep is less than 5,
             do not change the digit you are keeping.
       - When the digit beyond the one you want to keep is greater than 5,
             increase the digit you are keeping by 1.
       - When the digit beyond the one you want to keep is equal to 5, 
            And there are non-zero digits beyond it, increase the digit you are keeping by 1.
       - When the digit beyond the one you want to keep is equal to 5 exactly, 
            And the digit you are keeping is odd, increase the digit you are keeping by 1.
            If the digit you are keeping is even, keep it unchanged.
            (this odd vs even rule is also commonly known as the bankers rounding) 


  Viewing Analysis Files Notes:  
  -----------------------------
    Optionally use these files to review what occurred within SAS Statistics. 

    You can not Re Export/Analyze your TOP2/BOTTOM2 SAS file from Viewing Analysis Files,   
      because of the formatting and inclusion of means and percentages included on the final table.
      Analysis is only available from the Main Tab on TOP2/BOTTOM2 Analysis Screens.


  SAS Export/Import Files Names will be named MYTESTT2.* or MYTESTB2.* 
    where the T2 or B2 in file name indicates Top 2 or Bottom 2 Analysis.
