Ring-no-answer. A common form of nonresponse in telephone surveys is ""ring-no-answer."" That is, a call is made to an active number but no one answers. The Italian National Statistical Institute looked at nonresponse to a government survey of households in Italy during the periods January 1 to Easter and July 1 to August 31. All calls were made between 7 and 10 p. m., but 21.4% gave ""ring-no-answer"" in one period versus 41.5% ""ring-no-answer"" in the other period. 29 Which period do you think had the higher rate of no answers? Why? Explain why a high rate of nonresponse makes sample results less reliable.

The higher rate of no answers will most likely be in the period of July-August. because most people go on vacation 3 during these two months, which is not the case for the January-Easter.

A higher non response makes sample less reliable, because the higher the non response rate, the less representative the sample is for the entire population.
