Asap due today! : ( 2. tony decides to use observation. he visits 10 students and observes them doing schoolwork at home for 30 min. if a student looks at social media during that time, he notes it. (a) provide an advantage of using observation. (b) provide a disadvantage of using observation. (c) what are the sample and population for tony’s research? (d) suppose 3 of the 10 students looked at social media during the observation. what conclusion could tony make about the percent of high school students who use social media while doing schoolwork?

Answer

a) He carried the observation with different students instead of one. For a good research outcome one should have as many tests as possible. By using 10 students, that was an advantage in his observation.

b) 30 minutes was a very short time. He could have increased the time he took with each student. It takes more than 30 minutes to complete a single homework. So if it was possible to take more time with a single student, it could be better.

c) 10 students.

d) 30%

3 students out of 10 used social media while doing their homework.

That is : 3/10 × 100 = 30%.

30% of high school students use social media while doing homework.
