Which one of the following measures is determined only after the construction of cumulative frequency distribution?

The mean of 2,7,6 and \(x\) is 15 and the mean of \(18,16, x and y\)  is 10. What is the value of \(y\)?

If the median of the data \(4,7,x-1,x-3,16,25\) , written in ascending order, is 13 then \(x\) is equal to

The mean of 20 numbers is zero. Of them, at the most, how many may be greater than zero?

The median of first 8 prime numbers is

For a symmetrical frequency distribution, we have

1. 1. Mean<mode<median
   2. Mean>mode>median
   3. Mean=mode=median
   4. mode=\(\frac{1}{2}\)(mean+median)

The median and mode of a frequency distribution are 26 and 29 respectively. Then, the mean is

The mean and mode of a frequency distribution are 28 and 16 respectively. The median is

If the mean and median of a set of numbers are 8.9 and 9 respectively then the mode will be

Median=?

1. 1. \(l+{h\times \frac{(\frac{N}{2}-cf)}{f} }\)
   2. \(l+{h \times \frac{(cf-\frac{N}{2})}{f}}\)
   3. \(l-{h\times \frac{(\frac{N}{2}-cf)}{f} }\)
   4. None of these

Mode=?

1. 1. \(x_k +h.{\frac{(f_(k-1)-f_k)}{(2f_k -f_k-1 -f_k+1)}}\)
   2. \(x_k +h.{\frac{(f_k-f_k-1)}{2f_k -f_k-1 -f_k+1}}\)
   3. \(x_k +h.{\frac{(f_k - f_k-1)}{(f_k -2f_k-1 -f_k+1)}}\)
   4. \(x_k +h.{\frac{(f_k - f_k-1)}{(f_k -f_k-1 -2f_k+1)}}\)

If the ‘less than type’ ogive and ‘more than type’ ogive intersect each other at (20.5,15.5) then the median of the given data is

the relation between mean, mode and median is

1. 1. \(mode=(3\times mean)-(2\times median)\)
   2. \(mode=(3\times median)-(2\times mean)\)
   3. \(median=(3\times mean)-(2\times mode)\)
   4. \(mean=(3\times median)-(2\times mode)\)

while computing the mean of the grouped data, we assume that the frequencies are

In the formula, \(\overline {x}={A+\frac{\sum f_i d_i}{\sum f_i}}\) for finding the mean of the grouped data, the\(d_I\)  ’s are the deviations from \(A\)  of

For finding the mean by using the formula, \(\ovrerline{x}=A+h(\frac{\sum f_i u_i}{\sum f_i})\), we have \(u_i\)=?

1. 1. \(\frac{(A-x_i)}{h}\)
   2. \(\frac{(x_i -A)}{h}\)
   3. \(\frac{(A+x_i)}{h}\)
   4. \(h(x_i-A)\)

If \(x_i\)’s are the midpoints of the class intervals of a grouped data, \(f_I\)'s are the corresponding frequencies and \(\overline {x}\) is the mean then \(\sum f_i (x_i-\overline{x})=\)?

The abscissa of the point of intersection of the less than type and of the more than type cumulative frequency curves of a grouped data gives its

The cumulative frequency table is useful determining the

The median of a frequency distribution is found graphically with help of

The mode of a frequency distribution is obtained graphically from
