Question

Click on the table to see the data the researchers collected for each mimulus species. which variables are positively correlated with the volume of nectar production in this genus? select all that apply.

Answer 1

The variables that are positively correlated with the volume of nectar production are: the seeds per flower and the visits per flower.
Correlation is a statistical term describing the relationship between two variables. It shows whether two variables are related and the strength and nature of their relationship. A positive correlation indicates that when the values of one variable increase, there is an increase in the values of another variable as well. A negative correlation indicates that when the values of one variable increase, there is a decrease in the values of another variable. In this example, as the volume of nectar production increases in the five species of the genus Mimulus, there is also an increase in the seeds per flower and the visits per flower. Therefore, we can conclude that these three variables are positively correlated.
