I am trying to find the z-score using minitab. It worked for age but under heights its not working. I have numbers for the heights, like if a man is 5'9 that's 69. I have 40 different heights for men and women; 20 women and 20 men. If someone can help me because it's not coming up in the box. I go to Calculate then Standardize and the rows where I have under heights does not come up. I talked to my instructor and he said to put one number in and that should work. I don't understand that. Thank you.
