Variance and standard deviation are statistical measures used to understand the spread of data from its mean value. Variance measures the average of the squared differences of each value from the mean, while standard deviation measures the square root of the variance. In simple terms, standard deviation shows how much individual data points deviate from the mean, while variance is a measure of how spread out the data is.

To calculate variance, use the following formula: σ^2 = (Σ(x_i - μ)^2) / (n - 1), where σ^2 is the variance, x_i are individual data points, μ is the mean, and n is the number of data points. To calculate standard deviation, use the formula: σ = √σ^2.
Variance and standard deviation can be used in real-world scenarios such as predicting stock prices, understanding customer behavior, and identifying trends in sales data.
