In this video, I'll provide the simplest and the most effective ways to explore data in R, which will significantly speed up your work. Moreover, we'll go one step beyond EDA by starting to test our hypotheses with simple statistical tests... that's what I call "deep" here.
If you only want the code (or want to support me), consider join the channel (join button below any of the videos), because I provide the code upon members requests.
You of coarse don't need to see the whole thing:
Timetable:
00:50 - automated reports as a separate video ([ Ссылка ])
02:44 - exploring categorical variables
05:00 - descriptive statistics with some basic tests, like Fishers and Chi-Square, Mann-Whitney and Kruskal-Wallis tests
09:15 - explore distribution with skewness and kurtosis tests
13:03 - explore normality with Quantile-Quantile plots and Shapiro-Wilk normality test
17:20 - compare groups with box-plots and non-parametric tests, like Mann-Whitney and Kruskal-Wallis
19:12 - explore and visualize correlations and get correlation coefficients, confidence intervals and p-values
24:03 - explore linearity of data with non-linear models and ggplot2 package
24:30 - explore and impute NAs as a separate video ([ Ссылка ]) and outliers (part of this video)

By the way, one of the songs playing in the background is called ”Hypothesis” by the artist Vincent Rubinetti 😉
