Use of SOPARC to assess physical activity in parks: do race/ethnicity, contextual conditions, and settings of the target area, affect reliability?

^aObservations in areas where at least one of the two observers counted one or more people
^bAverage of the counts reported by the two observers
^cPercent of times where both observers counted the exact same number of people in the target area. In areas with 11 or more people, a < 10% discrepancy is still considered as agreement
