Positive Acceptance/No Unfamiliar report
The Positive Acceptance report discussed earlier, uses all scores available for a particular song when calculating its score. However, if you have many newer songs, which might not yet be totally familiar to your respondents, you might wish to run the Positive Acceptance / No Unfamiliar report. The base in-tab sample size for each song ignores any unfamiliar scores when the Positive Acceptance / No Unfamiliar report is tabulated.
Here's an example of how this could affect your results. Let's say you have two songs, and they each have a total of 100 scores. The first song might have 10 people that said they didn't know it (Unfamiliar scores), and 20 people that gave it a positive score. That song would be displayed on the standard Positive report as 20% Positive. Now, let's say there's a second song with 20 Positive scores, but it has 40 people that didn't know it. It too would be displayed on the standard Positive report as 20% Favorite. However, on the Positive / No Unfamiliar report, the first song would be displayed as 22% Positive (20 divided by 90); while the second song would leap to a score of 33% Positive (20 divided by 60, the number of people familiar with the song).
You can see what a great effect eliminating the Unfamiliar component from the Positive Acceptance report has. The second song in our example has a 50% higher Positive score, among those respondents familiar with the song, while they both have the exact same score among all respondents tested.
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.
