To prepare a frequency distribution with a class interval of 5, follow these steps:

Step 1: Organize the Data

The data is:
$8, 2, 6, 10, 11, 14, 21, 18, 10, 17, 16, 14$

Step 2: Determine the Class Intervals

The smallest value is 2, and the largest value is 21. With a class interval of 5, we can set up the following intervals:

• 0 - 4
• 5 - 9
• 10 - 14
• 15 - 19
• 20 - 24

Step 3: Tally the Data into the Class Intervals

Class Interval	Tally	Frequency
0 - 4	$\|$	1
5 - 9	$\| \| \|$	3
10 - 14	$\| \| \| \| \|$	5
15 - 19	$\| \| \| \|$	4
20 - 24	$\|$	1

Step 4: Frequency Distribution Table

\hline \text{Class Interval} & \text{Frequency} \\ \hline 0 - 4 & 1 \\ 5 - 9 & 3 \\ 10 - 14 & 5 \\ 15 - 19 & 4 \\ 20 - 24 & 1 \\ \hline \end{array}$$ This table represents the frequency distribution of the data set.

How would you find the median using this frequency distribution? 4. What is the cumulative frequency, and how is it useful? 5. How would you calculate the range from the given data? **Tip:** Always ensure the class intervals are consistent when constructing frequency distributions to maintain clarity and accuracy in the data.
