The one column of values above is body fat as a percentage of total body mass.

How would I find the mean and Standard Deviation individually for each column of data above?

Thank you in advance!

Answer 1

Repeated question....Read about functions mean, std . If T is your table.

% mean of column 1
m1 = mean(T.(1)) ;
std1 = std(T.(1)) ;
