Question

David recorded his finishing time, in seconds, for each time he ran the 100 m race during one track season. What was the median of his finishing times?

11. 9 11.9 12.0 12.1 12.1 12.2 12.3 12.4 12.4

Answer 1

The median is 12.1 because it is the center number in the sequence. This only applies if the numbers are in order from least to greatest, and also if there are a even number of numbers in the sequence you must take the average of the two center ones because there is no center one.
