Last year, Mr. Smith's biology class averaged 73 on their first test. This year, his new class averaged 87 on the same
test. Based on these results, is it reasonable to conclude that this year's class is more intelligent?
Yes, a grade of 87 is higher than a grade of 73.
Yes, the study was done in an academic setting.
No, the experiment was not double-blind.
No, there was no use of a placebo in the experiment.
No, there may be other differences between the two years besides the grades.


Sagot :

E. No, there may be other differences between the two years besides the grades.

This is because every kid is different and Mr. Smith might have just gotten a better group of kids the second year. This is just one factor of many viable options.

May I have brainliest please? :)
