This is how to do it in SPSS. Note that the most of the syntax is to
generate some data. You would need only the last 2 lines if you had your
data open.
* simulate some data.
new file.
input program.
vector x (10,f3).
loop id = 1 to 11.
loop #p = 1 to 10.
compute x(#p) = rv.normal(50,10).
end loop.
end case.
end loop.
end file.
end input program.
* the default number of samples is 1000.
BOOTSTRAP.
DESCRIPTIVES Variables = x1 to x10 /statistics = mean.
