Question

Positive or negative correlation? the ciameter of an apple and its weight.

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.

Expert Solution

Step 1

There should be positive correlation between diameter of apple and its weight.

Because if we increase diameter of apple then consequently weight of the apple increases and if diameter of apple decreases then weight of apple also decreases.
