Machine learning is a field of computer science that uses statistical techniques to build models from data. The ability to understand the principles of probability, hypothesis testing, and confidence intervals enables data scientists to validate their findings and ascertain the reliability of their analyses.

This is especially useful in finance and weather forecasting, where predictions guide decision-making. Hypothesis Testing : Statistical Models help test hypotheses by analysing relationships between variables. Techniques like linear regression, time series analysis, and decision trees are examples of predictive models.

Decision Trees: A supervised learning algorithm that creates a tree-like model of decisions and their possible consequences, used for both classification and regression tasks. Random Forest: An ensemble learning method that constructs multiple decision trees and merges them to improve accuracy and control overfitting.

Decision trees are more prone to overfitting. Underfitting: Here, the model is so simple that it is not able to identify the correct relationship in the data, and hence it does not perform well even on the test data. Some algorithms that have low bias are Decision Trees, SVM, etc. character) is underlined or not.
