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.
