The following two graphs represent the ages of the Sotos individuals and how many at each age have completed potty training or have stopped wetting the bed. For example, the first graph shows that there are 6 5-year-olds in the survey and that 5 are not potty trained but one is. All 7 10-years-olds are potty trained, but one 14-year-old is not.
At this point, I don't know the national averages for potty training and bed wetting; if anyone does, please contact me at Walter@Gilbert.net.
