Practice questions
Why can the median be better than the mean for skewed income or price data?
The median is less affected by extreme outliers, so it can better represent the typical value in a skewed distribution.
What does standard deviation measure?
Standard deviation measures how spread out values are around the mean; larger values indicate more variability.
Why is linear algebra important in machine learning?
Datasets, model weights, transformations, embeddings, and predictions are often represented and computed using vectors and matrices.
