You wonder if there has been any change in the time children spend on electronic devices (phones, tablets, etc.) over the past 5 years. You check a national website and it reports that between the years of 2016-2021 children aged 10-16 spent an average of 4.21 hours per day accessing some sort of electronic device. You survey 625 children of the same age in January of 2023 and get the following results (mean time = 4.11 hours, St Dev = 1.2) What would you conclude? What is the effect size?
