Graph to plot anthropometric indices against reference population

This graph provides the normal distribution for z scores. To plot your anthropometric curves you need to follow these steps: 1)Double click on the table to see the data sheet (see below) 2) You will need to summarize the data into the 24 z-score categories. See the next slide for and example of an SPSS program to create the categories. 3) Type in your percentages into the Powerpoint Datasheet – do not change the “reference” percentages

Example SPSS Code * For a Z-score distribution. * HAZ. RECODE haz (-6.0 throu -5.5=-5.75) (-5.5 thru -5.0=-5.25) (-5.0 thru -4.5=-4.75) (-4.5 thru -4=-4.25) (-4 thru -3.5=-3.75) (-3.5 thru -3=-3.25) (-3 thru -2.5=-2.75) (-2.5 thru -2=-2.25) (-2 thru -1.5=-1.75) (-1.5 thru -1=-1.25) (-1 thru -.5=-.75) (-.5 thru 0=-0.25) (.0001 thru.5=.25) (.5001 thru 1=.75) ( thru 1.5=1.25) ( thru 2=1.75) ( thru 2.5=2.25) ( thru 3=2.75) ( thru 3.5=3.25) ( thru 4.0=3.75) ( thru 4.5=4.25) ( thru 5.0=4.75) ( thru 5.5=5.25) ( thru 6.0=5.75) INTO haz_grps.
