In this study the independent variable was considered as the sleeping habits and the dependent variable was considered as the behavior of the child. It was seen that the children who had sleep disorders had behavioral issues. Your friend thinks that due to the fact that the children had sleeping disorders they had behavioral issue.

Cotton was king in Louisiana because of its beautiful bolls,
And bales of rich value, the Master controls.

The world to acknowledge that “Cotton is King.”
