Improve code quality by:

• Changing variable names to something more meaningful
• Making the program robust

clc
clear
format long
f=input('Enter name of file: ','s');
A=load(f);

fprintf('Press 1 for meannPress 2 for mediannPress 3 for modenPress 4 for standard deviationnPress 5 for quitn');
n=input('Enter choice: ');

if (n==1)
    fprintf('Mean is %fn',Sum(A)/length(A));
elseif (n==2)
    Z=sort(A);
    n=length(Z);
    t=(n+1)/2;
    m=(Z(floor(t))+Z(ceil(t)))/2;
    fprintf('Median is %fn',m);
elseif (n==3)
    C = unique(A);
    z=zeros(1,length(C));
    for i=1:length(C)
        z(i) = sum(A == C(i));
    end
    m = find(z == max(z));
    fprintf('Mode is %fn', C(m));
elseif (n==4)
    AA = sum(A)/length(A);
    SD = sqrt(sum((A-AA).^2)/(length(A)-1));

Take the program you improved, and improve it further by making it modular (think user defined functions)
