A. Mean: The sum of all values in a dataset divided by the number of values. It gives the average value.

B. Median: The middle value in a dataset when it is arranged in order. If there’s an even number of values, it’s the average of the middle two.

C. Mode: The value that appears most frequently in a dataset.

D. Standard deviation: A measure of the amount of variation or dispersion in a set of values. It indicates how spread out the values are from the mean.

(b) For the given sets of data:

A. Mean: (2 + 3 + 5 + 7 + 9 + 9 + 10 + 11 + 14 + 18) / 10 = 8.8
Mode: The mode is 9 since it appears twice, which is more frequent than other values.

B. Mean: (3 + 5 + 8 + 10 + 12 + 15 + 16 + 2 + 3 + 4 + 4 + 5 + 5 + 7 + 7 + 7 + 9) / 17 = 6.06 (approx)
Mode: The mode is 7 since it appears three times, which is more frequent than other values.
