I trying to use SPSS to analyze existing data that was given to me and I'm not too familiar with the software. There are missing values for various variables in the data. Is there a command in SPSS to delete all of them from the sample so that my final sample consists of those who answered all questions for the different variables?

Also for frequencies, when determining the percentage of values that fall above the mean given in the first box with statistics, do you find the same value given for the mean in the “valid” column of the second box listing frequencies and add percent of responses that fall above that number? Any help is appreciated. Thanks,
