Here's the script that works for me:
pkg load signal
pkg load statistics
N=5 %setting a value for N for 5 numbers
Sum=0 %initilalsing the sum to @ to be used to calculate sum

for i = 1:N %for Loop starting from 1 and ending at 5
In(i) = input('Please enter numbers: '); %asks user to input a number
and will loop 5 times
Sum = Sum + In(i); %used to calculate the sum

endfor

Am = 1/(N) * Sum; %Formula to find Aritmetric mean

Qm = sqrt((In(1)^2 + In(2)^2 + In(3)^2 + In(4)^2 + In(5)^2) / N);
%Formula to find Quadradic mear
Hm = N/ (1/In(1) + 1/In(2) + 1/In(3) + 1/In(4) + 1/In(5));%Formula to
find Harmonic mean

fprintf('\n The Arithmetic mean is %2.2f',Am); %Prints answer to screen
fprintf('\n The Quadratic mean is %2.2f',Qm);
fprintf('\n The Harmonic mean is %2.2f\n' ,Hm);

arithmetic = mean(In) %Finding the same answers using the build in functions
quadratic = rms(In)
harmonic = harmmean(In)
