Summary and Schedule
Learning Objectives
- Describe the importance of efficient and reproducible data QA/QC
- Identify common data errors and quality issues
- Develop a QA/QC strategy for a tabular data set
- Import data into R and QA/QC using default data types
- Implement an R script to perform data QA/QC on a tabular data set
- Document and communicate data QA/QC steps for data reporting
Prerequisite
This lesson assumes you have R and RStudio installed on your computer. R and RStudio are two separate pieces of software:
- R is a programming language and software used to run code written in R.
- RStudio is an integrated development environment (IDE) that makes using R easier. In this course we use RStudio to interact with R.
If you don’t already have R and RStudio installed, follow the instructions for your operating system below. You have to install R before you install RStudio.

you can give a general overview of the software used in this lesson here
and fill out the individual operating systems (and potentially add more,
e.g. online setup) in the solutions blocks.
