Two genes in a melanoma patient are found to have a correlation coefficient of 0.92. This indicates that these two genes.
a. behave similarly: slight relationship
b. behave similarly: strong relationships
c. behave differently: strong relationships.
d. behave differently: slight relationship
of course, b.
The correlation coefficient measures the strength and direction of the relationship between two variables. In this case, the correlation coefficient between the two genes in a melanoma patient is 0.92. The correlation coefficient ranges from -1 to +1.
A correlation coefficient of +1 indicates a perfect positive relationship, meaning that as one gene increases, the other gene also increases in the same proportion. A correlation coefficient of -1 indicates a perfect negative relationship, meaning that as one gene increases, the other gene decreases in the same proportion.
In this case, the correlation coefficient is 0.92, which is very close to +1. This indicates a strong positive relationship between the two genes. Therefore, the correct answer is:
b. behave similarly: strong relationships.
