Answer #1

The correlation is linear.

The given equation is the equation of a straight line. where y is dependent variable and x is independent variable. On changing the values of x, we will get values of y according to the slope (0.2284) and intercept (13.81) given.

Any equation of the form y = ax + b is equation of straight line with slope a and intercept b. The power of x decides the correlation. Here, power of x is 1 so correlation is linear (straight line). when power is 2, correlation is quadratic and when power is 3 correlation is cubic and so on.

Further, as slope is positive, correlation is positive. This means that on increasing values of x, y will also increase and vice versa.

The correlation between x, ( the diameter of the tree), and Y (the tree’s height) is 0.875064.   A coefficient of correlation of 0.875064 indicates a strong correlation between the independent variable and the dependent variable.   In general, if Y tends to increase along with X, there's a positive relationship. QUESTION: What does this mean in terms of the problem?    Is it a strong correlation? is it statistically significant?
