Question

The following data give the points scored in a tennis match by two player X and Y at the end of twenty games:

(10,12)	(2,11)	(7,9)	(15,19)	(17,21)	(12,8)	(16,10)	(14,14)	(22,18)	(16,4)
(15,16)	(22,20)	(19,15)	(7,18)	(11,11)	(12,18)	(10,10)	(5,13)	(11,7)	(10,10)

Taking class intervals as: 5−9, 10−14, 15−19..., for both X and Y, construct a Bivariate Frequency Distribution.

Answer 1

The given data can be presented in the form of a bivariate frequency distribution as follows.

Player Y	Player X					Total
	0 − 4	5 − 9	10 − 14	15 − 19	20 − 24
0 − 4						1
5 − 9						3
10 − 14						8
15 − 19						6
20 − 24						2
Total	1	3	8	6	2	20
