Recording data is an important step that encompases several issues: coding, verifying, organizing, trasforming, etc. Here, you can study some of these aspects and also the utility of the tidyverse package in R
The need for statistics arises from the variability of samples. A sample contains information on the original population from where we obtained it. As any sample is different we need some approach to infer the population properties from the results we see in a sample.
Explore the meaning of mean, variance, percentiles, etc. Also, you can explore the concept of reference interval, sample variability and the distribution of the sample mean.
The tidyverse package offers a number of functions for data organization, filtering, summarizing, etc. In this document, we discuss its basic functions.
