Much like the standard "PEMDAS" rule in mathematics, R follows a specific hierarchy to ensure calculations are consistent.

Dot Plots in R The "dot plots in R" typically refers to two distinct types of visualizations: (i) Cleveland dot plots (for comparing categories) and (ii) Stacked (Wilkinson) dot plots (for showing distributions). A dot plot is a graphical representation that breaks the range of data into many small equal-width intervals and counts the number of observations in each interval. The interval count is superimposed on the number line at the interval midpoint as a series of dots (stacked if repeated), usually one for each observation.

Ordinary Least Squares (OLS) assumes that every observation has the same variance (homoscedasticity). Weighted Least Squares (WLS) is used when observations have different variances heteroscedasticity
