Mr. jacobs wants to find out whether a new program for teaching physical education promotes students' physical development. he gives his students a number of tests before they begin the program (pretests) and the same tests again after they have been in the program for eight months (posttests). he finds that the students' posttest scores are higher than their pretest scores and so concludes that the program is effective. what is definitely wrong with mr. jacobs' conclusion?

The one thing that is wrong with Mr. Jacobs' conclusion is that he has failed to consider that there can be other possible explanations for his results.

Explanation:

no , per capita income is not a true measure of the development because: -it only tells us about average income not how income is distributed among the people.it only give us an idea of the economic aspect.it is only at the qualitative basis.moreover, income is not only the way of development other factors are also as much as important as income.

whats the question huh huh bruh
