Abbreviation: METs, metabolic equivalents.
a
Data are the mean (standard error) METs of people assessed in 16 parks observed 3 times per day on 3 weekdays and 1 weekend day.
b
From two-way analysis of variance, season main effect is significant: winter > spring; fall > summer.
c
From two-way analysis of variance, like letters (d,e,f,g,h,i) in the same row are not significantly different by Tukey contrasts.
