Prerequisites

I'm happy to say that there is no prerequisite knowledge needed in R Programming, Data Science, or Machine Learning.

A basic understanding of statistical analysis will help. This includes understanding of:

• Measures of central tendency (mean, median, mode)
• Measures of spread (standard deviation)
• Understanding of Histograms (frequency distributions)
• Measure of relationship between the data for 2 features / variables (correlation)

If the terms above are new to you, you can quickly research basic stats concepts in these short resources:
