The question asks for the "range" (ragam) of the given data set:

$3, 5, 4, 5, 6, 8, 7, 9, 6, 6, 5, 7, 9, 5, 8, 3$

Step 1: Identify the range

The range of a data set is the difference between the highest and lowest values.

• Maximum value: 9
• Minimum value: 3

Step 2: Calculate the range

$\text{Range} = \text{Maximum value} - \text{Minimum value} = 9 - 3 = 6$

It seems like the provided answers are fractions, which means the question may not directly be about the simple range but could refer to variance or something similar. However, based on the basic understanding of "ragam," the answer should be the difference between the highest and lowest values.

The range of the data is 6.

Do you need more details on how to compute variance, or is this answer sufficient?

Here are some additional related questions:

1. How is the variance of a dataset calculated?
2. What is the formula for calculating standard deviation?
3. How does the range help describe data variability?
4. Why might variance or standard deviation be more informative than range?
5. How do outliers affect the range of a dataset?

Tip: Always check the context of a question, as some terms like "ragam" might refer to variance or range depending on the context.
