The logarithmic regression equation for a stalk of corn is y = -76.2 + 37.8 ln(x)
What are regression equations?
Regression equations are used to determine the relationship between the variables of a scatter plot dataset
Below are the steps to determine the logarithmic regression equation
To determine the logarithmic regression equation, we make use of a graphing calculator with the following calculation summary:
- Mean of x = 17.55
- Mean of y = 31.75
- Correlation coefficient r = 0.99133
- A = -76.2
- B = 37.8
A logarithmic regression equation, is represented as:
y = A + B ln(x)
Substitute the values of A and B in y = A + B ln(x)
y = -76.2 + 37.8 ln(x)
Hence, the logarithmic regression equation is y = -76.2 + 37.8 ln(x)
