Group by and Summarise functions in R programming - use the tidyverse package to wrangle your data

The video tutorial introduces the functions 'group by' and 'summarize' in R, emphasizing their importance in data wrangling. It covers the use of the Tidyverse package for data manipulation and explores R's built-in datasets for practice. The tutorial provides a detailed explanation of the code for grouping and summarizing data, including handling missing values. It demonstrates how to calculate averages and maximums for different categories using the 'M Sleep' dataset, highlighting the importance of data cleaning and summarization techniques.
