Basing a definition on something observable is not itself enough to make a definition operational, because different observers may still define what is to be observed differently. Try this simple example: light a candle and sit quietly around it with two or three other people. for fi ve minutes, let each person silently count the number of times the candle flame flickers. after fi ve minutes, compare your counts. do not be surprised to see numbers varying from 2 to 2000. yet each of you was watching the same candle flame! The problem was that each of you was defining ‘flicker’ in a different way. now, work as a group to develop a common definition of ‘flicker’, and then watch the flame again for five minutes. using this agreed-upon definition of ‘flicker’, do the individual number counts of the group come closer to agreement?

how could you measure the following so that the observations would meet the requirements of an operational definition?
