Question 1
What is the formula for calculating range?
- Range = Maximum Value + Minimum Value
- Range = Maximum Value - Minimum Value
- Range = Minimum Value - Maximum Value
💡 Hint: Think about how you find the spread of numbers.
Question 2
True or False: A higher standard deviation indicates that data is less spread out.
- True
- False
💡 Hint: Consider the meaning of the term 'spread out'.

Challenge Problems
Push your limits with challenges.
Question 1
Given the data points [5, 10, 15, 20], calculate the range, variance, and standard deviation.
💡 Hint: Break the problem down into parts: find range first, then mean for variance.
Question 2
Consider a set of exam scores: [50, 75, 100, 95]. Discuss how you would assess the variability and what measures you would use.
💡 Hint: Use the steps we learned to conduct the assessment.
