“…Avoidable absence has generally been found to be inversely related to age in male samples (Bernardin, 1977 [2 samples]; Hill, 1967;Nicholson et al, 1977 [9 samples]; Taylor, 1967aTaylor, , 1967bTucker & Lotz, 1957;Walker & de la Mare, 1971 [3 samples]). However, positive (Baumgartel & Sobol, 1959;Buzzard &Shaw, 1952;Cooper & Payne, 1965 [2 samples]), U-shaped (de la Mare & Sergean, 1961;Hedges, 1977;Shepherd & Walker, 1957), inverted-U-shaped (Collins, 1962;Isambert-Jamati, 1962), and nonsignificant relationships (Baumgartel & Sobol, 1959;Cooper & Payne, 1965 [2 samples]; de la Mare & Sergean, 1961;Gordon, Emerson, & Pugh, 1959;Ivancevich & McMahon, 1977;Metzner & Mann, 1953;Nicholson et al,.1977 [3 samples]; Taylor, 1967a) have also been reported for male avoidable absence. The Nicholson et al (1977) study included two measures of avoidable absence for 12 samples.…”
