Solution
(a) The best measure to summarize the data for the house prices would be the Median. This is because the data contains an outlier ($474,000) which would significantly skew the Mean. The Mode is not applicable as none of the prices are repeated.
(b) The measure that gives the score Tom shot most often in golf would be the Mode. This is because the Mode represents the most frequently occurring value in a data set.
(c) The best measure to summarize the data for the number of email advertisements Hans received per day would be the Mean. This is because there are no outliers in the data, and the Mean would provide an average number of emails received per day.
