7. The number of wins by a hockey team in the last 8 years: {56, 45, 26, 48, 54,
52, 49, 38} Mean or Medan or Mode

Answer 1

(a) Mean

(b) Mean

Explanation:

(a) Mean is influenced by two things, occurrence and difference in values. Mode is influenced by one thing only, occurrence. Median is positional in rank order so only indirectly influenced by value.

(b) The mean is the most accurate way of deriving the central tendencies of a group of values, not only because it gives a more precise value as an answer, but also because it takes into account every value in the list.
