✍️ Sample MS-DS Master of Data science Questions & Answers

1. What is the primary purpose of the kernel trick in Support Vector Machines?

✓ To implicitly map input features into a higher-dimensional space without computing the transformation explicitly

The kernel trick allows SVMs to find a linear separating hyperplane in a higher-dimensional feature space by computing inner products via a kernel function, avoiding the computational cost of explicit transformation.

2. What is the purpose of A/B testing in a data-driven organization?

✓ To compare two versions of a variable to determine which performs better

A/B testing is a controlled experiment where two variants are compared to measure which one produces a better outcome on a specific metric.

3. When comparing more than two group means simultaneously, a one-way ANOVA is preferred over multiple t-tests because:

✓ Multiple t-tests inflate the Type I error rate

Running multiple t-tests increases the familywise error rate; ANOVA controls it by testing all groups in a single analysis.

4. In the context of Shapley values (SHAP), what does a negative SHAP value for a feature indicate?

✓ The feature decreased the model's prediction relative to the average prediction

A negative SHAP value means that feature's contribution pushed the model's output below the baseline (average prediction), indicating it reduced the predicted value for that instance.

5. Which test is most appropriate to assess whether two continuous variables are linearly associated when both are normally distributed?

✓ Pearson correlation test

Pearson correlation tests linear association between two normally distributed continuous variables and is parametric.

6. A researcher uses bootstrapping to estimate the standard error of the median. What does this method fundamentally rely on?

✓ Resampling with replacement from the observed data to approximate the sampling distribution

Bootstrapping treats the empirical distribution as a proxy for the population and resamples with replacement to build an approximate sampling distribution.
