Question

Comment on the mode for the following data showing the time taken (in seconds) for 8 competitors in a running race:

25.2, 26.5, 28.6, 32.1, 29.0, 29.3, 31.3, 27.8

Answer 1

Time taken (in seconds) by 8 competitors in a running competition is as follows :
25.2, 26.5, 28.6, 32.1, 29.0, 29.3, 31.3, 27.8

Here, each observation occurs only once. Therefore by definition of mode, it cannot be found for the given data. But it may be obtained by using the empirical formula of mode.
