ling. By spplying sampling error stetistics to these
figures it was possible to show thet if 100 like samp-
les of boys rere used the chances would be over 98 out
of 100 that the results would be in favor of the exer-
cise group. However, in the case of my Westport boys
in Kensas City thet difference is alrost a true diff-
erence beceuse ve had such a large proportion of the
entire group.

I em gled the figures creme out so es to esse your mind
about causing the influenza, but I ar still wondering
what would happen if the study rere to include the girls
end to enver e longer period of time.

Dad, I am just one jump ahead af you on that point.

Girls were included in a follow-up study for the three-
week influenze period, end they elso produced results
in fevor of daily gymnesium classes. An edditionel
study covering a rhole semester geve the sare results
for both boys end girls. It seers to me thet we herve

a definite cese of "physical educetion for health”.
