Is deepseek-v4-pro-high good at Data & Analytics?

“The model correctly calculates the probability as 20/69 (approx 29%), perfectly matching the expected answer. It shows its work clearly using both Bayes' theorem and natural frequencies, and provides a helpful interpretation of why the false positive rate leads to this result.”

“The model's final answer perfectly matches the correct answer. It correctly identifies Pool A as the better pool, explicitly names Simpson's Paradox, accurately calculates the shift mix to explain the confounder, and provides excellent business recommendations.”

“The model's final answer perfectly matches the correct answer. It correctly identifies the statistical error (peeking/optional stopping), explains why it invalidates the result (inflated false-positive rate), and provides the correct methodological solutions (fixed sample size or sequential testing). It also adds valuable context about the winner's curse.”
