While there are four Positive options you can choose to include in your scoring, there is only one "Favorite" option. All of the Positive attribute score options that you offer are included in calculating "Positive Acceptance" for any reports that include that variable. However, if you want to isolate only the scores of the respondents that selected "Favorite" as their score for each song, then you must run the Favorite report. (There is also a Rolling Averages version of the Favorite report, which displays other song attributes for each song. The Basic weekly trend Favorite report displays only the favorite score, in a 4-week trend.)
The end date you specify in the filter determines what scores will be included in this report. All scores for the 6-day period prior to the End Date you enter on the filter screen will be calculated and displayed under the column to the far right. Scores from 7-13 days prior to the End Date you enter will be under the Last Week column; scores from 14-20 days before the End Date you enter will fall into the second column, and scores from 21-27 days before the End Date you specify will be displayed under the first column.
As you can see, the date you select as your End Date is critical in determining which week particular scores belong to. For example, if today is Tuesday, a score from last Wednesday would be included as part of "This Week" (the 7-day period defined as "This Week" would include all scores collected between and including last Wednesday and today, Tuesday). But tomorrow (Wednesday), that same score will become part of the "Last Week" score totals, as it has now moved one day further away from the End Date you specify for your research report.
The Favorite score is calculated by counting how many of the total scores for each song during the defined testing period were "Favorite". For example, if 20 people out of a sample of 100 said that a particular song was their Favorite; this song would be displayed as having a 20% Favorite score.
