What is the lowest level of measurement for the data where the mode could be
determined?
A. Nominal
B. Ordinal
C. Interval
D. Ratio

Consider a data set of 11 distinct measurements with mean equal to A and median equal
to B. If the highest value was decreased to a value smaller than the median B, how would
the mean and median be affected?
A. The mean and median will both decrease.
B. The mean and median will not change.
C. The mean will not change and the median will decrease.
D. The mean will decrease and the median will not change.

What is one distinction between a parameter and a statistic?
A. A parameter is only based on conceptual measurements, but a statistic is based
on a combination of real and conceptual measurements.
B. A statistic changes every time you try to measure it (using different samples), but a
parameter remains fixed.
C. A parameter changes each time you try to measure it, but a statistic remains fixed
across samples.
D. The true value of a statistic can never be known but the true value of a parameter
can be known.

Which of the following is NOT TRUE about the boxplot?
A. The boxplot shows the mean of the data.
B. The boxplot shows the median of the data.
C. The boxplot gives an indication of the spread of the data.
D. The boxplot indicates the presence of outliers in the data.

Suppose we wish to test H0: μ ≤ 53 vs Ha: μ > 53. What will result if we conclude that the
mean is greater than 53 when in fact the true value of the mean is 55?
A. We have committed a Type I error.
B. We have made a correct decision based on the test.
C. We have committed a Type II error.
D. None of the above.
