Study Notes
Foundations of Data Science
- Linear Algebra: is essential for understanding data science, particularly operations involving vectors and matrices.
- Correlation: is a statistical measure that signifies the strength and direction of a relationship between two variables.
- Principal Component Analysis (PCA): a mathematical technique for dimensionality reduction, transforming data into a set of linearly uncorrelated variables by finding the principal components.
- Normal Distribution: a commonly used probability distribution to model random variables in data science as it often closely approximates the distribution of data points.
- Hypothesis testing: helps determine statistically significant differences between observed data and expected outcomes to test hypotheses and make data driven decisions.
