MatLab code to solve for standard deviation.

Comment

% To compute the standard deviation and variance
% where L - Load, f - frequency

L = [30.6 30.8 31.2 31.4 31.6 31.8];
f = [4 10 16 12 5 3];

x = L .* f;
n = sum(f);
n_mean = sum(x) / n; %data mean

% Corrected calculation of variance
L1 = (L - n_mean).^2; % Square the difference from the mean
L2 = sum(L1 .* (f / n)); % Weighted sum
St = sqrt(L2); % Standard deviation
Variance = L2; % Variance

fprintf('Standard Deviation: %.4f\n', St);
fprintf('Variance: %.4f\n', Variance);
