Which of the following samples has the largest standard error?

a. n = 25, standard deviation = 10


b. n = 25, standard deviation = 20


c. n = 100, standard deviation = 10


d. n = 100, standard deviation = 20

Which of the following samples has the largest standard error?
standard error=standard deviation/square root of n





(a) 10/5=2


(b) 20/5=4


(c) 10/10=1


(d) 20/10=2





b has the largest
