Question 1 :
If the difference between the mode and median is $2$, then the difference between the median and mean (in the given order) is?

Question 2 :
Fill in the blank.<br>An Ogive representing a cumulative frequency distribution of 'more than' type is called a $___________$.

Question 3 :
The mean and median of same data are 24 and 26 respectively. The value of mode is :<br>

Question 4 :
The curve obtained by joining the points, whose $x$-coordinates are the upper limits of the class-intervals and $y$-coordinates are corresponding cumulative frequencies is called -<br/>

Question 6 :
If the sum of the mode and mean of the certain frequency distribution in $129$ and the median of the observations is $63$, mode and mean are respectively

Question 7 :
100 surnames were randomly picked up from a local telephone directory and the frequency distribution of the number of letters in the English alphabets in the surnames was obtained as follows:<br><table class="wysiwyg-table"><tbody><tr><td>No. of letters<br></td><td>No. of surnames<br></td></tr><tr><td>1-4<br></td><td>6<br></td></tr><tr><td>4-7<br></td><td>30<br></td></tr><tr><td>7-10<br></td><td>40<br></td></tr><tr><td>10-13<br></td><td>16<br></td></tr><tr><td>13-16<br></td><td>4<br></td></tr><tr><td>16-19<br></td><td>4<br></td></tr></tbody></table>Determine the median number of letters in the surnames. Find the mean number of letters in the surnames? Also, find the modal size of the surnames<br>

Question 8 :
If in &#160;a moderately asymmetrical distribution mean and mode are &#160;$9a, 6a $ respectively then median is equals,

Question 9 :
The mean and median of the data are respectively $20$ and $22$.&#160;The value of mode is:<br/>

Question 10 :
Find the median where mean and mode are given as $10$ and $7$.<br/>
