Question

Some of you may wonder how data are collected about something that does not seem to be measurable, such as people’s level of disobedience. Psychologist Stanley Milgram devised the following experiment: A researcher instructed a volunteer subject to operate a control board that gave increasingly painful “electrical shocks” to a third person. Actually no real shocks were given, and the third person was an actor. The volunteer began with 15 volts and was instructed to increase the shocks by increments of 15 volts. The disobedience level was the point at which the subject refused to increase the voltage. Surprisingly, two-thirds of the subjects obeyed orders even though the actor screamed and faked a heart attack. The number 2/3 represents this.

a) Parameter

b) Population size

c) Sample size

d) Statistic

e) None of the above

Explanation / Answer

This 2/3 is proportion based on sample and hence, this will be a statistic.

Option d is correct.
