Problem 4: Compare Cross-Validation Mean and Standard Deviation for Two Models

Problem Description

Write a Python program that performs 5-Fold Cross-Validation on both a Logistic Regression model and a Decision Tree model, comparing their mean scores and standard deviations.

Input

A labeled dataset.

Output

Mean and standard deviation for both models.

Constraints

• At least 15 labeled examples.

Example Input

text
(A labeled dataset with 15+ examples)

Example Output

text
Logistic Regression: Mean=0.90, Std=0.05
Decision Tree: Mean=0.85, Std=0.12

Concepts Covered

cross_val_score(), .mean(), .std(), model comparison.
