Challenge Problems
Push your limits with advanced challenges
In a dataset consisting of the ages of participants at a party: {15, 22, 24, 22, 30, 35, 40}, calculate the mean, median, and mode. Discuss how each measure could be affected by an outlier, such as a participant aged 70.
💡 Hint: Calculate the values first, then consider the effect of the outlier.
Given the dataset {2.5, 3, 4.5, 3, 5, 5, 7}, identify the measures of central tendency and explain their importance in the context of research data collection.
💡 Hint: Identify each measure before discussing its relevance.
