Challenge Problems
Push your limits with advanced challenges
Consider the dataset: [10, 20, 30, 40, 50]. Normalize it using Min-Max scaling. What are the results?
💡 Hint: Use the formula: (value - min) / (max - min).
Given the dataset with mean 200 and standard deviation 50, standardize the value 300. Explain the significance of standardizing this value.
💡 Hint: What does the resulting z-score signify in terms of data distribution?
