I am trying to do a chi squared test on the means of this data which I have already sorted and is not the issue here. However, my observed values are just 4 ones even though I inputted the means I calculated. Does anyone know why this happens and how to solve it? Your help would be appreciated.
a=readmatrix("DIP Project- Population.xlsx");
population=a(:,1);
production=a(:,7);
gr1gen36=a(61:90,7);
gr1gen36(isnan(gr1gen36))=0;

m1=mean(gr1gen36);

gr2gen36;
m2=mean(gr2gen36);
gr3gen36=a(241:270,7);
gr3gen36(isnan(gr3gen36))=0;
m3=mean(gr3gen36);
gr4gen36=a(331:360,7);
gr4gen36(isnan(gr4gen36))=0;
gr4gen36;
m4=mean(gr4gen36);
