Devon wants to know if drinking milk before bed teenagers sleep. he chooses 10 friends on his high school basketball team for his study. every night for one month the friends drink a glass of milk before bed and later record how many hours they sleep that night. describe three reasons why devon's study design is flawed.

The three reasons Devon's study is flawed because:

1. The sample size is very small. You cannot conclude anything based on small samples.

2. Sample is biased as Devon chose basket ball players and such players have proper sleep pattern and waking up pattern as compared to normal people. So, the study cannot be generalized.

3. Devon must have studied their sleep pattern before experimenting also, so that some quantitative data on change is available for conclusion.

126 maybe. sorry
