Scenаriо: Leаh is а mоm оf 4 kids and wanted to try and see whether or not a technique that she had read about in one of her parenting books would be helpful. The book stated that giving children a weekly allowance, regardless of the amount, would reduce the number of times that children would ask for a toy when going to the store. So Leah decided to give 2 of her children an allowance and not give an allowance to the other 2. She recorded the number of times that each child requested a toy while they were out shopping for an entire month. At the end of the month, Leah didn't notice a significant difference between her children that had received an allowance and those that hadn't. Is the scenario described above an example of an experimental study or an observational study? Explain how you arrived at your answer and be as specific as possible.
