State Summary Key:
terms presented across the top of the chart:
State - self-explanatory
Colleges - the number of responding colleges in a given state
Finale - the number of responding colleges in a given state that use Finale, although not necessarily to the exclusion of Sibelius
Sibelius - the number of responding colleges in a given state that use Sibelius, although not necessarily to the exclusion of Finale
F & S - the number of responding colleges in a given state that use both Finale & Sibelius
Mac OS - the number of responding colleges in a given state that use the Mac OS platform, although not necessarily to the exclusion of Windows
Windows - the number of responding colleges in a given state that use the Windows platform, although not necessarily to the exclusion of the Mac OS
M & W - the number of responding colleges in a given state that use both the Mac OS & Windows platforms
Fin/Coll* - expressed as a decimal number, the percentage of colleges in a given state that use Finale, calculated by dividing the number of colleges in a state that use Finale by the total number of colleges in that state. Example: 11 colleges from Alabama responded to the survey. 9 of those colleges reported using Finale. 9 divided by 11 = 0.82, indicating that Finale is used in 82% of the colleges reporting from Alabama.
Sib/Coll* - expressed as a decimal number, the percentage of colleges in a given state that use Sibelius, calculated by dividing the number of colleges in a state that use Sibelius by the total number of colleges in that state. Example: 11 colleges from Alabama responded to the survey. 4 of those colleges reported using Sibelius. 4 divided by 11 = 0.36, indicating that Sibelius is used in 36% of the colleges reporting from Alabama.
Sib/Fin - expressed as a decimal number, the percentage of Sibelius use compared to Finale use in a state, calculated by dividing the number of colleges in a state that use Sibelius by the number of colleges in that state that use Finale***. Example: 9 colleges from Alabama reported the use of Finale, while 4 reported the use of Sibelius. 4 divided by 9 = 0.44, indicating that Sibelius has 44% of the market in comparison to that of Finale in the schools responding from Alabama.
Mac/Coll** - expressed as a decimal number, the percentage of colleges in a given state that use the Mac OS, calculated by dividing the number of colleges in a state that use the Mac OS by the total number of colleges in that state. Example: 11 colleges from Alabama responded to the survey. 5 of those colleges reported using the Mac OS. 5 divided by 11 = 0.45, indicating that the Mac OS is used in 45% of the colleges reporting from Alabama.
Win/Coll** - expressed as a decimal number, the percentage of colleges in a given state that use Windows, calculated by dividing the number of colleges in a state that use Windows by the total number of colleges in that state. Example: 11 colleges from Alabama responded to the survey. 9 of those colleges reported using Windows. 9 divided by 11 = 0.82, indicating that Windows is used in 82% of the colleges reporting from Alabama.
Win/Mac - expressed as a decimal number, the percentage of Windows use compared to Mac OS use in a state, calculated by dividing the number of colleges in a state that use Windows by the number of colleges in that state that use the Mac OS***. Example: 5 colleges from Alabama reported the use of the Mac OS, while 9 reported the use of Windows. 9 divided by 5 = 1.8, indicating that Windows has 180% of the market in comparison to that of the Mac OS in the schools responding from Alabama. Put another way, for every school in Alabama that uses the Mac OS there are 1.8 schools that use Windows. Put a third way, reverse the equation: 5 divided by 9 = 0.56, indicating that the Mac OS has 56% of the market in comparison to that of Windows in the schools responding from Alabama.
terms presented across the bottom of the chart:
Coll Total - total number of responding colleges in all states
Fin Total - total number of responding colleges in all states that use Finale, although not necessarily to the exclusion of Sibelius
Sib Total - total number of responding colleges in all states that use Sibelius, although not necessarily to the exclusion of Finale
F & S Total - total number of responding colleges in all states that use both Finale & Sibelius
Mac Total - total number of responding colleges in all states that use the Mac OS platform, although not necessarily to the exclusion of Windows
Win Total - total number of responding colleges in all states that use the Windows platform, although not necessarily to the exclusion of the Mac OS
M & W Total - total number of responding colleges in all states that use both platforms
Fin Avrg - expressed as a decimal number, the percentage of all colleges that use Finale, calculated by dividing the total number of colleges in all states that use Finale by the total number of colleges. Translation: A total of 668 colleges responded to the survey nationwide. 554 of those colleges reported using Finale. 554 divided by 668 = 0.82, indicating that Finale is used in 82% of responding colleges.
Sib Avrg - expressed as a decimal number, the percentage of all colleges that use Sibelius, calculated by dividing the total number of colleges in all states that use Sibelius by the total number of colleges. Translation: A total of 668 colleges responded to the survey nationwide. 320 of those colleges reported using Sibelius. 320 divided by 668 = 0.48, indicating that Sibelius is used in 48% of responding colleges.
Sib/Fin - expressed as a decimal number, the percentage of total Sibelius use to total Finale use, calculated by dividing the total number of colleges that use Sibelius by the total number of colleges that use Finale***. Translation: Nationwide, 554 colleges reported the use of Finale. 320 colleges reported the use of Sibelius. 320 divided by 554 = 0.58, indicating that Sibelius has 58% of the market in comparison to that of Finale.
Mac Avrg - expressed as a decimal number, the percentage of all colleges that use the Mac OS, calculated by dividing the total number of colleges in all states that use the Mac OS by the total number of colleges. Translation: A total of 668 colleges responded to the survey nationwide. 506 of those colleges reported using the Mac OS. 506 divided by 668 = 0.76, indicating that the Mac OS is used in 76% of responding colleges.
Win Avrg - expressed as a decimal number, the percentage of all colleges that use Windows, calculated by dividing the total number of colleges in all states that use Windows by the total number of colleges. Translation: A total of 668 colleges responded to the survey nationwide. 384 of those colleges reported using Windows. 384 divided by 668 = 0.57, indicating that Windows is used in 57% of responding colleges.
Win/Mac - expressed as a decimal number, the percentage of total Windows use to total Mac OS use, calculated by dividing the total number of colleges that use Windows by the total number of colleges that use the Mac OS***. Translation: Nationwide, 506 colleges reported the use of the Mac OS. 384 colleges reported the use of Windows. 384 divided by 554 = 0.76, indicating that Windows has 76% of the market in comparison to that of the Mac OS.
*Since colleges that report using Finale may also use Sibelius and vice versa, the total percentages for colleges that use Finale added to the colleges that use Sibelius will, in many cases, exceed 100%. Example: In Alabama, 82% of colleges use Finale and 36% of colleges use Sibelius. The fact that 82% + 36% is greater than 100% and, therefore, may appear to be an error, is irrelevant in that it does not take into account that some of the colleges use both applications.
**Since colleges that report using the Mac OS may also use Windows and vice versa, the total percentages for colleges that use the Mac OS added to the colleges that use Windows will, in many cases, exceed 100%. Example: In Alabama, 45% of colleges use the Mac OS and 82% of colleges use Windows. The fact that 45% + 82% is greater than 100% and, therefore, may appear to be an error, is irrelevant in that it does not take into account that some of the colleges use both platforms.
***In calculating percentage of use, I consistently applied this formula: numbers of the application or platform with overall lower values divided by numbers of the application or platform with overall higher values. Therefore, Sibelius numbers are always divided by Finale numbers, even when, on occasion, Sibelius outperforms Finale. The same is true on the platform side: Windows numbers are always divided by Mac OS numbers since Mac OS values are generally higher than Windows values.
