13
18
Consider the data
The lower limit of the modal class is
115
165
145
175
For any collection of n items,
∑x

0
The median class of the following distribution is
20 - 30
40 - 50
30 - 40
50 - 60
The width of a rectangle in a histogram represents
mid values of the class
class interval
frequency of the class
numbers of class
The class mark of a class interval is
lower limit + upper limit
upper limit - lower limit
1/2(lower limit + upper limit)
1/4(lower limit + upper limit)
The mean of 9, 11, 13, P, 18, 19 is P. Then the value of P is
