Push your limits with advanced challenges
Imagine you have a dataset consisting of people's ages and incomes. The ages range from 10 to 80 years, and incomes from $20,000 to $120,000. If you were to apply Min-Max Scaling, show how the transformed values for age 40 and an income of $50,000 would appear.
💡 Hint: Apply the Min-Max Scaling formula for each value.
Provide a scenario where applying Min-Max Scaling can lead to misleading results and explain why.
💡 Hint: Reflect on the effects of extreme values in normalization.
