Definitions:

Variance

A statistical measurement that represents the dispersion of a dataset relative to its mean, used to quantify the spread of data points.

Regression

A statistical method for estimating the relationships among variables, often used for prediction and forecasting in finance.

Correlation Coefficient

A statistical measure that calculates the strength of the relationship between two variables, ranging from -1 to 1, where 1 indicates a perfect positive correlation and -1 indicates a perfect negative correlation.

Standard Deviation

A statistical measure that represents the dispersion or variability of a data set or investment returns, indicating how much the values in the set deviate from the mean.
