BROODINESS AND FECUNDITY IN FOWL

:i{. Correlation Between the Presence of Broodiness and Annual Production

Tbe correlation coefficient is negative and less than tiiree times its probable 

 error. The conclusion seems to be warranted that in the 1916 flock there is 

 no significant correlation between broodiness and annual production.

 above the Mean of Broodies and Non-broodies Combined — Pullet Year (Im- 

 proved Flock 1923).

Coefficient of correlation

This coefficient is about four times its probable error and is probably of 

 some significance. The degree of correlation between broodiness and annual 

 production is slight on the two years studied; a fact that probably indicafes 

 more correlation on the intervening years.
