3. Find the Means of the above data and describe the data based on its frequency distribution.

1.	Range = Χmax - Χmin
		97-32
	R         =	65
2.	K         =	1 + 3,333 * log (n)
		1 + 3,333 * log (90)
		1 + 3,333 * 1,95424
		1 + (3,333 * 1,95424)
		1 + 6,51348
	K         =	7,51348
	K         =	8
	P         =	R/K
		65/7,51348
	P         =	8,65112
	P         =	9
