What are the merits and demerits of median. Calculate the median from the following distribution:

Class:	$5-10$	$10-15$	$15-20$	$20-25$	$25-30$	$30-35$	$35-40$	$40-45$
Frequency:	$5$	$6$	$15$	$10$	$5$	$4$	$2$	$2$

The median of the following frequency distribution is equal to

The mean of a data set comprising of $\mathrm{16}$ observations is $\mathrm{16}$. If one of the observation value $\mathrm{16}$ is deleted and three new observations valued $3,\; 4$ and $\mathrm{5}$ are added to the data, then the mean of the resultant data is

Consider the following frequency distribution:

If mean $=\frac{309}{22}$ and median $=14,$ then the value $(a-b{)}^2$ is equal to

Find median from the following data:

The mean and median of  $7, 5, 5, 2, 7, 6, 5, 3, 7, 6$is-

1. $5.3$ and $5$

2. $5$ and $5.5$

3. $5$ and $6$

4. $5.3$ and $5.5$

Consider the following frequency distribution :

If the sum of all frequencies is $584$ and median is $45$, then $|\alpha -\beta |$ is equal to            .

In a survey, the speeds of 100 vehicles were observed. The following table gives the distribution of vehicle speed and the corresponding number of vehicles.

The median speed of the vehicles is:

The following is the price of Cabbage over 12 months. What is the median price?
