Dear student, please comment in the case of any doubt and I would love to clarify it
We will be applying the Linear regression model here, it can be done by using the function LINEST(y_value, x_value, TRUE, TRUE) where y_values contain values of y here and x_values have x values.
Select 5 rows and 2 columns and then write the formula in the first cell and after that, press Shift + Ctrl + Enter.
The equation comes out to be-
y = 0.21 + 1.03*x
The correlation comes out to be 0.88, it was calculated using the function CORREL(array1, array2) where array1 is x values and array2 is y values.
