(N/A) To represent the given data using a bar graph,follow these steps:
$1$. Draw two perpendicular axes on a graph paper: a horizontal axis ($X$-axis) and a vertical axis ($Y$-axis).
$2$. Along the $X$-axis,represent the 'Score' values $(1, 2, 3, 4, 5, 6)$ at equal intervals.
$3$. Along the $Y$-axis,choose a suitable scale to represent the 'Frequency'. For example,$1 \text{ unit} = 2 \text{ units of frequency}$.
$4$. Draw rectangular bars of equal width for each score,where the height of the bar corresponds to its respective frequency:
- For score $1$,draw a bar of height $15$.
- For score $2$,draw a bar of height $13$.
- For score $3$,draw a bar of height $20$.
- For score $4$,draw a bar of height $17$.
- For score $5$,draw a bar of height $20$.
- For score $6$,draw a bar of height $15$.
$5$. Ensure there is a uniform gap between the bars.

Construct a histogram to represent the data above.

The mean of $10$ observations is $48$. If each observation is divided by $3$,what will be the new mean?

After arranging the observations in ascending or descending order,the observation which is obtained in the middle is called .............. of the data.

In a frequency distribution,the mid value of a class is $10$ and the width of the class is $6$. The lower limit of the class is:
