Challenge Problems
Push your limits with advanced challenges
Given a dataset containing: 12, 22, 22, 36, 47, 50, and 68, classify the data points, draw tally marks for each interval, and compute the total frequency.
💡 Hint: Use the class intervals carefully while classifying.
If a study shows frequencies of: 0-10: 3, 10-20: 5, and 20-30: 4, what classifications would change if 2 more numbers are added to the 10-20 group?
💡 Hint: Focus on how new data affects the existing count.
