The range of a set of data is calculated by subtracting the smallest value from the largest value.

Given the data:
14, 4, 6, 10, 3, 5

1. Find the largest value:
   The largest value is 14.

2. Find the smallest value:
   The smallest value is 3.

3. Calculate the range:
   $\text{Range} = \text{Largest value} - \text{Smallest value} = 14 - 3 = 11$

So, the value of the range is 11.

Here are 5 follow-up questions:

1. How do you calculate the mean of the given data set?
2. What is the median of the data set?
3. Can you explain how the variance is calculated for a set of data?
4. How do you calculate the standard deviation from the variance?
5. How does the range relate to the interquartile range in data analysis?

Tip: When calculating the range, always ensure to correctly identify the smallest and largest values in your data set. This will avoid errors in your result.
