Note, in a recent post, you learn how to quickly explore your data with one of Tukey’s exploratory data analysis methods: Whether new to R or looking to expand your data analysis skills, this tutorial will provide the knowledge and tools needed to work confidently with descriptive statistics in R. Additionally, we will learn how to create a LaTeX table with descriptive statistics and how to save descriptive statistics to a CSV file for future analysis.īy the end of this tutorial, you will have a solid understanding of using R to calculate and interpret descriptive statistics. We will also explore how to use the psych and dplyr packages to calculate summary and descriptive statistics by group. These measures help us understand the data’s spread and can be used to identify outliers or unusual observations. Next, we will dive into measures of variability, including the standard deviation, interquartile range, and quantiles. We will also cover less commonly used measures of central tendency, such as geometric, harmonic, and trimmed mean. Then, we will explore how to calculate measures of central tendency, such as the mean and median, and how to calculate them by one or two groups. We will start by installing the necessary R-packages and importing data.

What do I do?” If you’re asking yourself this, this book is for you. Statistical Inference via Data Science: A ModernDive into R and the tidyverse byĬhester Ismay and Albert Y. Most of the cheatsheets have been translated into multiple languages. You can keep them handy at your desk and quickly jog your memory when you get stuck. These cheatsheets have been carefully designed to pack a lot of information into a small amount of space. We highly recommend pairing R4DS with the It’s designed to take you from knowing nothing about R or the tidyverse to having all the basic tools of data science at your fingertips.
