    "From page 50 of the text..." I went to page 50 on the book to add the formula for the Z score. It is not there. It'd be nice if you had the formula on the bottom of the video.

      mary garibay p. 50 states z = x- x-bar /SD in words, this means the z score is equal to the value minus the mean divided by the Standard Deviation or you can copy and paste this into the expression area:
      ("var1"- mean("var1" )) / std("var1")
      The parentheses direct statcrunch to use that variable (the value in the column)

    I entered the data exactly as you have and I still got different summary statistics, what am I doing wrong? Further, I typed the Z-score formula exactly as you have written it and I got another different answer.
