What is the range for the dataset {5, 8, 12, 15}?
Calculate by finding the maximum and minimum values.
Identify the maximum and minimum values in the dataset {20, 25, 30, 40}.
Look for the largest and smallest numbers.
What does the range measure in a dataset?
Remember the definition of range.
Is it true that a higher range indicates more variability in data?
Consider what a larger range signifies.
You have the following datasets: {2, 4, 6, 8} and {10, 20, 30}. Calculate the range for both and analyze which dataset has greater variability.
Calculate each range separately.
If you added the value 5 to the original dataset {1, 2, 3, 4}, how would this change the range?
Remember to compute the new max and min after adding a value.
