R Studio - Finding & Excluding Outliers via Boxplots
In today's video, I'll show how to find and remove (potential) outliers by means of boxplots. Some main points are -creating decent boxplots in R Studio -looking up the exact values for outliers -basic strategies for when & how to exclude outliers -removing outliers with a basic ifelse function and checking the results. Hope it helps!
