    An analyst samples random stocks from the market using the simple random sampling method. The first stock sampled returned 10% in 2012, and the mean 2012 return of the analyst’s entire sampled portfolio is 14%. If the market return in 2012 was 16%, the absolute value of the analyst’s sampling error is closest to:

    • 2%
    • 4%
    • 6%

    It’s the difference between the same and the population right? I am assuming the market return would be the population

    The sampling error is the difference between the observed
    value and the value it was intended to represent. In this case, the observed
    value was the mean return, or 14%. The actual mean return was 16%, so the
    sampling error was 2%.
