ρ

\rho

The Greek letter rho (\rho) is commonly used in mathematics and science to represent various concepts, such as density, correlation coefficient, and resistivity, depending on the context.

Examples

ρ = \frac{m}{V}

Represents density, where m is mass and V is volume.

\rho = \frac{m}{V}

ρ (X, Y) = \frac{cov ( X , Y )}{σ _{X} σ _{Y}}

Represents the Pearson correlation coefficient between random variables X and Y.

\rho(X, Y) = \frac{\text{cov}(X, Y)}{\sigma_X \sigma_Y}

R = ρ \frac{L}{A}

Represents electrical resistivity, where R is resistance, L is length, and A is cross-sectional area.

R = \rho \frac{L}{A}
