The population to be studied is unclear.
In this research question, the population to be studied is not clearly defined. Are the chickens in the study limited to Tyler's pet chickens or does it refer to all chickens in general? Without specifying the population, it is difficult to draw meaningful conclusions from the data collected. A more effective question would specify the population of interest, such as "Do Tyler's pet chickens exhibit differences in happiness levels based on the number of chickens in their cage?"
