1.
Statistics
The abscissa of the point of intersection of the less than type and of the more than type cumulative frequency of a grouped data gives its:
2.
Statistics
The mode and mean is given by 7 and 8, respectively. Then the median is:
3.
Statistics
If the arithmetic mean of x, x + 3, x + 6, x + 9 and x + 12 is 10, then x = ?
4.
Statistics
The mean of the data: 4, 10, 5, 9, 12 is;
5.
Statistics
While computing mean of the grouped data, we assume that the frequencies are:
6.
Statistics
If the mean of first n natural numbers is 5n/9, then n =?
7.
Statistics
If x1, x2, x3,….., xn are the observations of a given data. Then the mean of the observations will be:
8.
Statistics
If the mean of frequency distribution is 7.5 and ∑fi xi = 120 + 3k, ∑fi = 30, then k is equal to:
9.
Statistics
The median of the data 13, 15, 16, 17, 19, 20 is:
10.
Statistics
If the mean of first n natural numbers is 3n/5, then the value of n is
11.
Statistics
If AM of a, a+3, a+6, a+9 and a+12 is 10, then a is equal to;
12.
Statistics
The Median when it is given that mode and mean are 8 and 9 respectively, is:
13.
Statistics
The class interval of a given observation is 10 to 15, then the classmark for this interval will be:
14.
Statistics
If 35 is removed from the data, 30, 34, 35, 36, 37, 38, 39, 40 then the median increases by:
15.
Statistics
If the sum of frequencies is 24, then the value of x in the observation: x, 5,6,1,2, will be;
