Question 2

A researcher has numbered all 50 states from 1 to 50 and has calculated a mean of 17.43 for the variable "state of birth."

Accepted Answer

A) Since the variable is nominal,the mean makes no sense. 
B) Since the variable is ordinal,we should treat the value of the mean with great caution. 
C) The variable is interval-ratio and the mean is an appropriate and useful statistic in this case. 
D) Since this variable is discrete,the mean should not be computeD. 
A) Since the variable is nominal,the mean makes no sense. 
B) Since the variable is ordinal,we should treat the value of the mean with great caution. 
C) The variable is interval-ratio and the mean is an appropriate and useful statistic in this case.

Accepted Answer

A) it may be impossible to find all members of a certain population. 
B) social scientists don't have the time or money to test an entire population. 
C) some of the population might not cooperate. 
D) samples are sometimes accurate representations of the population but can't always be used to generalize.
