✍️ Sample MS Questions & Answers
1. What does the second law of thermodynamics state about entropy?
The second law states that the total entropy of an isolated system can only increase over time, never decrease, for any real process.
2. What is 'meta-analysis' in psychological research?
Meta-analysis aggregates data from multiple independent studies using statistical techniques, producing a pooled effect size estimate with greater statistical power than any single study.
3. In distributed computing with Apache Spark, what is a 'shuffle' operation and why is it expensive?
A shuffle redistributes data across all executors (e.g., during groupBy or join), requiring extensive network transfer and disk I/O, making it Spark's most costly operation.
4. What is the purpose of the US Preventive Services Task Force (USPSTF)?
The USPSTF is an independent, volunteer panel of experts that reviews evidence and issues recommendations on preventive services including screenings, counseling, and preventive medications.
5. Which regression technique applies a penalty to large coefficients to prevent overfitting?
Ridge regression adds an L2 regularization penalty (λΣβ²) to the loss function, shrinking large coefficients and reducing overfitting.
6. What does Universal Design for Learning (UDL) aim to accomplish?
UDL proactively incorporates multiple means of engagement, representation, and action/expression to make learning accessible for all students, including those with diverse abilities and backgrounds.
