b. Median =
c. If I change the last value (2) into a 20 , recalculate:
Mean =
Median =
What is meant by a biased statistic?
a. The average value for the statistic overestimates the corresponding population parameter.
b. The average value for the statistic underestimates the corresponding population parameter.
c. The average value for the statistic either overestimates or underestimates the corresponding population parameter.
d. The average value for the statistic is exactly equal to the corresponding population parameter.
