In the 3rd Age Interval, determine the following:
Class Interval:
20-24
Class Limit:
Upper Class Limit (UCL):
24
Lower Class Limit (LCL):
20
Class Boundary:
Upper Class Boundary (UCB) = UCL + 0.5 =
24.5
Lower Class Boundary (LCB) = LCL - 0.5 =
19.5
Class Mark = (UCL + LCL)/2 =
22
Class Size = UCL – LCL +1 =
5
