A positive correlation (r=60) is found between time spent outside at age four and creativity in kindergarten.

Describe what prediction can be made in regards to creativity in kindergartden for a child who spent a lot of time outside at age four.

If a journalist made an error in causality when writing an article about these findings, what would they be concluding based on this scenario?

If the researcher had a sample size of 13 and started with a directional hypothesis, what was the critical r value?

Should she reject or fail to reject her null hypothesis?

Expert Solution

A positive correlation (r=0.60) is found between time spent outside at age four and creativity in kindergarten.Describe what prediction can be made in regards to creativity in kindergarten for a child who spent a lot of time outside at age four.

A child who spent a lot of time outside at age four has more creativity in kindergarten.

If a journalist made an error in causality when writing an article about these findings, what would they be concluding based on this scenario?

Journalist concluded that child who spent a lot of time outside at age four causes creativity in kindergarten.

If the researcher had a sample size of 13 and started with a directional hypothesis, what was the critical r value?

Df=n-2=13-2=11

Critical value ( one sided)= 0.476

Should she reject or fail to reject her null hypothesis?

Since calculated r=0.60 is > 0.476, we reject the null hypothesis.

A study found a high positive correlation (r = .921) between the size of the hospital where a patient's surgery was performed and the length of the patient's stay following surgery. (x = number of beds in the hospital, y = number of days following surgery before release from the hospital). Is the most reasonable explanation for this correlation cause-and-effect or a hidden cause? If it is not cause-and-effect, suggest a more reasonable hidden cause.
