discuss the problem in a drawing the stated conclusion in each of the following circumstances.
19. Discuss the problem in drawing the stated con- clusion in each of the following circumstances a. A certain health club claims that the corre- lation is .85 between length of time en- rolled in its exercise program and pounds lost. The fact is advertised as proof that the program causes weight loss. b. A theory of reading suggests that the per- formance of certain physical exercises re- quires the same neurological activity as does reading. A study of 100 children aged 6-14 reveals a correlation.Explanation / Answer
Correlation is a measure of the relationship between the two variables. It measures the strength of the relationship between two or more normally distributed interval or ratio level variables. The relationship can be positive or negative, in the positive relationship as one value increases another value increases with it. In the negative relationship as one value increases the other one decreases.
a. The correlation between the length of time enrolled in the exercise program and the pounds lost is 0.85, which is positive. As the people enrolled in the exercise program the weight of the people will decrease as the length of time increases, thus the value of correlation will be negative. But in this scenario, the weight of the people increases, so the value of correlation between the length of time enrolled in the exercise program and the pounds lost 0.85 indicates a wrong conclusion.
b. The performance of certain physical exercise will provide relax in the children aged 6-14, and a result it will provide a better reading way. So the theory concludes the correct decision that certain physical exercise requires the same neurological activity as does reading.
