To find the range of a set of data, you subtract the minimum value from the maximum value.
First, let's find the minimum and maximum values in the given data set:
-
Data set:
- 217, 235, 212, 253, 233, 171, 184, 301
- 256, 297, 247, 226, 237, 241, 195, 204
- 197, 214, 166, 309, 281, 303, 309, 299
-
Finding the minimum value:
- The smallest number is 166.
-
Finding the maximum value:
- The largest number is 309.
Now, we can calculate the range:
\[ \text{Range} = \text{Maximum} - \text{Minimum} = 309 - 166 = 143 \]
The range of the data is 143.
