Given a dataset of temperatures over a week: [30, 32, 35, 29, 31, 34, 33], calculate the variance and standard deviation, and interpret the results in terms of how stable the temperatures are.
💡 Hint: Calculate the mean first to ease finding deviations.
Discuss the implications of high variance in the design of a control system for a mechanical device. Why is it critical to address this during PDE analysis?
💡 Hint: Consider how variability affects performance.
