A data has 25 observations (arranged in descending order). Which observation represents the median?
12th
13th
14th
15th
Consider the data
The lower limit of the modal class is
115
165
145
175
For the following distribution
the modal class is
20 - 30
30 - 40
40 - 50
50 - 60
The mean and median of a uni - nodal grouped data are 72.5 and 73.9 respectively. Then mode is
73
73.5
75.4
76.7
The mode when median is 125.6 and mean is 128 is
120.8
119.7
120.5
119.8
The mean of 9, 11, 13, P, 18, 19 is P. Then the value of P is
10
12
14
15
The width of a rectangle in a histogram represents
mid values of the class
class interval
frequency of the class
numbers of class
The mean and median of a data are 14 and 15 respectively.The value of mode is
16
17
13
18
The formula is used to determine
Mean
Mode
Median
All the three above
Which of the following is true?
Mode = 3 Median + 2 Mode
Mode = 3 Median - 2 Mean
Mode = 2 Median + 3 Mode
Mode = 2 Median - 3 Mean
