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

Can the mean, median and mode of data coincide?

• Yes

• No

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

• a histogram

• a frequency curve

• a frequency polygon

• ogives

Find the class mark of class 35-55

• 45

• 46

• 47

• 48

The graphical representation of a cumulative frequency distribution is called

• Bar graph

• Histogram

• Frequency polygon

• Ogive

An ogive is used to determine

• Standard deviation

• Median

• Mode

• Mean

In a frequency distribution the class having maximum frequency is called the modal class

• TRUE

• FALSE

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
