I learned about correlation analysis, linear regression with three variables, creating 3D plots, analyzing residuals plots, and understanding the planes formed in 3D plots while considering three variables in the previous class. I additionally looked at how quadratic equations can be used in data analysis.

I’ve been working on graphs that incorporate data on diabetes, inactivity, and obesity. My current focus is on plotting the linear regression plane within the 3D plot, which I hope will provide useful information about the correlations between these variables.
