For a certain distribution,mode and median were found to be 100 and 1250 respectively. Find mean for this distribution using an empirical relation

• 1375

• 1265

• 1145

• 1550

The mean, median and mode of grouped data are always different

• TRUE

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

• a histogram

• a frequency curve

• a frequency polygon

Find the mean value of x

• 24.5

• 3.5

• 2.45

• 10

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

• Mean

• Median

• Mode

• Class

The relationship between mean, median and mode is

.............median = 2 .......... + ...........

• 2,median, mode

• 3,median, mode

• 2,mean, mode

• 3,mean, mode
