A note on the effect of recording frequency on the estimation of grazing time of cattle and sheep
Length of time spent in an activity can be estimated by observations at fixed time-intervals. By illustration with 3 sets of data, this report shows that the formula proposed by Mullen et al. in 1980 substantially under-estimates the accuracy of estimation for grazing time.
