The points scored by a Kabaddi team in a series of matches are as follows:
$17, 2, 7, 27, 15, 5, 14, 8, 10, 24, 48, 10, 8, 7, 18, 28$
Find the median of the points scored by the team.

$5$ people were asked about the time in a week they spend doing social work in their community. They said $10, 7, 13, 20$ and $15$ hours,respectively. Find the mean (or average) time in a week devoted by them for social work.

$A$ family with a monthly income of $20,000$ had planned the following expenditures per month under various heads:

Grocery	$4$
Rent	$5$
Education of children	$5$
Medicine	$2$
Fuel	$2$
Entertainment	$1$
Miscellaneous	$1$

Draw a bar graph for the data above.

The relative humidity (in $\%$) of a certain city for a month of $30$ days was as follows:

$98.1$	$98.6$	$99.2$	$90.3$	$86.5$	$95.3$	$92.9$	$96.3$	$94.2$	$95.1$
$89.2$	$92.3$	$97.1$	$93.5$	$92.7$	$95.1$	$97.2$	$93.3$	$95.2$	$97.3$
$96.2$	$92.1$	$84.9$	$90.2$	$95.7$	$98.3$	$97.3$	$96.1$	$92.1$	$89$

$(i)$ Construct a grouped frequency distribution table with classes $84-86, 86-88$,etc.
$(ii)$ Which month or season do you think this data is about?
$(iii)$ What is the range of this data?

Three coins were tossed $30$ times simultaneously. Each time the number of heads occurring was noted down as follows:
$\begin{array}{llllllllll}0 & 1 & 2 & 2 & 1 & 2 & 3 & 1 & 3 & 0 \\ 1 & 3 & 1 & 1 & 2 & 2 & 0 & 1 & 2 & 1 \\ 3 & 0 & 0 & 1 & 1 & 2 & 3 & 2 & 2 & 0\end{array}$
Prepare a frequency distribution table for the data given above.

In a city,the weekly observations made in a study on the cost of living index are given in the following table:

Cost of living index	Number of weeks
$140-150$	$5$
$150-160$	$10$
$160-170$	$20$
$170-180$	$9$
$180-190$	$6$
$190-200$	$2$
Total	$52$

Draw a frequency polygon for the data above (without constructing a histogram).
