During 2007-2008, faculty and staff at My University received an 8% raise. In determining if there will be raises allocated at My University during the current year, the board of trustees asks that there be research conducted on how much variation there was in the percentage of raise allocated at similarly sized institutions across the U.S. The institutional research office contacts 100 similarly sized institutions and gathers data on the raise, measured in percentage, that they allocated during the past fiscal year. The institutional research office computes the standard deviation on the 'percentage of raise allocated.' Is this appropriate given the measurement scale of this variable?
