clear,clc
data=xlsread('standing.xlsx');
accy=data(:,2);
inc=120;
for i=1:inc:length(accy)-rem(length(accy),inc);
j=i+inc-1;
dev =std(accy(i:j,:))
end

inc = 120;
accy(length(accy)-rem(length(accy),inc)+1:end) = [];
accy_2D = reshape(accy, inc, (length(accy)-rem(length(accy),inc))/inc);
dev = std(accy_2D);

the second line removes the numbers after the row 1201.
The third line reshape this one vector to a 2D-Array with 120 rows, and 10 columns.
The last calculate std in each column
