The authors of our text state: "We have 40 years of data across multiple studies that confirm the positive correlation between taking a course in critical thinking and improvements in the students' pretest to post-test critical thinking skills scores. It would be a mistake, therefore, all things being equal, to say that growth in critical thinking and taking a course in critical thinking are unrelated" (p. 290). The null hypothesis is false. Does that mean, therefore, that taking a critical thinking course causes students to become more skilled at critical thinking and more motivated to use those skills? Explain your answer.

Yes

Explanation:

It is true that taking a critical thinking course causes students to become more skilled at critical thinking and more motivated to use those skills.

Critical thinkig might be an in born quality in some people but it can definitely be developed and enhanced as well and that is only possible through practicing and application of critical thinking. The more one's mind focus on something, the more better it gets into it.

To support this, one can have some ranking before the practice and then a post evaluation. The difference in two tests would yeild the improvement done. But if a person is not practicing something, it is difficult that he can get better on that

the median of the data is 4.

step-by-step explanation:

the median means the middle number of a given number.

to decide which one is the median, arrange in ascending or descending order. but sometimes, you may find two(2) number in the middle, but it's easy, just add them together and divide by 2.

so,   determine the median of the data. 2, 3, 3, 4, 5, 7, 9

it is already arranged, count 3 times forward and 3 backward and the one left is your answer.

2,3,3,4,5,7,9

our answer is 4.

hope this !
