Challenge Problems
Push your limits with advanced challenges
A research team collected temperature readings over a month: [70, 72, 68, 75, 74, 72, 71]. Calculate the mean, median, mode, and standard deviation.
💡 Hint: Sort the readings first for median, and calculate averages for mean and mode.
Imagine you have two datasets:
1. Dataset A: [45, 50, 55, 60]
2. Dataset B: [40, 60, 70, 80]
Discuss how the standard deviations of both datasets might affect the decision-making process.
💡 Hint: Compare the spread of values in each dataset to understand their implications.
