Printed Compatibility report
The Compatibility Report allows you to select a sample song, and compare all other songs tested that same week with it.
After selecting Compatibility Report from the reports menu, you'll see a list of song titles. Highlight and select the Target song you wish all other titles to be compared with. Generally, this would be one of your better-testing songs, or a song that best represents the sound of your station.
When the song is selected, you'll see the title and artist, along with the dates the song was first tested and last tested. If this is the song you wish to run click Ok, or click Cancel to return without running the report.
When you get to the Report Filter, enter the date range you wish to analyze. This must be within the range of dates when the reference song was actually tested. Also, the date range should coincide with a regular full week of research. The reason for this is simple. The compatibility report selects a subset of respondents that gave a favorable rating to your reference song (people who were Unfamiliar or Tired with the song or said they didn't like it are ignored). Once this subset is derived, only the scores from those respondents are used to calculate the scores for all other songs that were tested.
Here's a good way to visualize how this report works. In the sample report above, we have selected Larger Than Life by Backstreet Boys as our reference song. Let's pretend that we have all the respondents for the current test cycle (January 5-19 in this example), in the same room at the same time. Now, we ask all people who like this song, Larger Than Life, to move to one side of the room. Once we have them isolated from all other respondents (those who didn't like the reference song), we have just these people rate all the other songs in our test. Then, we rank all the other songs in descending order, based on how much they like those songs. That's what the Compatibility report is doing, in essence. It's pulling just the scores for all other songs in your test from the respondents that liked whatever song you selected as your reference song when you ran the Compatibility report. As you'll see in the sample report, to no great surprise, the other songs in our sample test that were most compatible with the Backstreet Boys song were from artists like Britney Spears, Christina Aguilera and Mark Anthony.
Because of the methodology employed in the Compatibility report, you can only compare songs with your reference song that were also scored by these same respondents.
In other words, one of the limitations of the Compatibility Report is that you may only compare and contrast a particular song with other songs that the same group of respondents also rated. You can not, for example, select a song from this week's test, and compare it with songs that were tested three weeks ago; two totally different groups of respondents were used to score each set of songs.
The songs that are most compatible with the reference song will appear at the top of the list; those that were least compatible, or least liked, will be at the bottom the list. The songs are ranked by Positive Acceptance (the determining factor for compatibility), but Familiarity, Burn Factor and Dislike for each song are also displayed.
The "n=" number, or total sample size, is indicated in the top right corner of the report. This number will vary, depending on which song you're testing. Again, you are selecting a subset of respondents that rated the sample song favorably. Therefore, a high-testing song will have a higher "n=" number (more respondents rated it positively) than a poor-testing song (fewer favorable responses).
The Compatibility Report is helpful in determining what other songs listeners would like to hear next to your reference song... as well as what songs they would most likely not like to hear adjacent to your reference song. While you probably don't want to run a Compatibility report for every song you're testing, it is useful to run for a couple of the highest testing songs for each test cycle.
