A data has 25 observations (arranged in descending order). Which observation represents the median?
12th
13th
14th
15th
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
If mode = 80 and mean = 110 then the median is
110
120
100
90
The formula is used to determine
Mean
Mode
Median
All the three above
The median class of the following distribution is
20 - 30
40 - 50
30 - 40
50 - 60
Consider the data
The lower limit of the modal class is
115
165
145
175
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
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
