The best way to begin learning about Statistics is to gain an understanding of basic concepts. Start by familiarising yourself with terms such as mean, median, and mode and how they apply to numerical data sets. Next, practice using descriptive methods to summarise your findings from collected data. Finally, get comfortable with performing statistical tests on given samples; this will help develop your skills in making inferences from data analysis.
Once you have acquired basic Statistics fundamentals, it's time to dive deeper into more complex topics like linear regression and probability distributions.
