Paola C. Santiago Ortiz Linear Models Instructions Create a new thread and answer both parts of the initial prompt below: 1. Find an image of a linear regression graph on the internet. o The image you choose should have the horizontal and vertical axes labeled with units, and you should be able to locate the regression equation. o If you are stuck, search for the term linear regression. 2. For the image you choose, answer the following: o What does the slope of the equation represent in terms of the units on the axes?
As the variable x increases, the variable increases and the slope also increases. The value of the slope is 0.71. o What do the x-intercept and y-intercept represent in terms of the units on the axes? The analysis of the relationship between the variables X and Y can be determined by putting them on a graph with intersection in X and in Y. o Identify the dependent variable and independent variable in terms of the units on the axes. The independent variable is in the intercept of X which is income. The dependent variable is at the Y-intercept, which is happiness. o What is the correlational relationship between the two variables? In conclusion, it can be determined that there is a correlation between income and happiness. This can be determined by the fact that as the variable X increases, the variable y increases. And because the slope is positive. References https://www.scribbr.com/statistics/linear-regression-in-r/ Brase, C. H., & Brase, C. P. (2018).
