JAMB - Mathematics (1983 - No. 1)
If M represents the median and D the mode of the measurements 5, 5, 3, 5, 7, 5, 8 and 9, then (M, D) is
(6, 5)
(5, 8)
(5, 7)
(5, 5)
(7, 5)
Explicació
First re-arrange the given data in the form 3, 5, 5, 5, 7, 8, 9.
3, 5, 5,|5| 7, 8, 9
median(M) = 5
mode(D) = 5
(M, D) = (5, 5)
