I ran a proc means procedure to get mean and standard deviation for my data. However, the length for them are 12, eg, mean=0.0578154391, std=0.0245687672. I only want to have 3 decimal places and total length is 5, that is, mean=0.057, std=0.024, and they still have to be numeric. How should I do it? Thank you very much.
Sorry I didn't make myself clear. I also used the output statement in proc means prodecure and get a sas dataset: data1 to include the mean and std, I mean how to change the length of mean and std in data1.
