Who is this course for?
High quality datasets are essential for statistical analysis. This course is for researchers that need to use the open source R programming language to prepare their data for statistical analysis. The course uses R Studio to illustrate the various techniques that can be used to prepare a data set that is analysable by statistical methods.
Attendees are expected to be familiar with the data collection process using an electronic tool, such as MS Excel.
The course is a four-hour practical session and will use the open source R Studio software. It will focus on the R data frame and its manipulation. Items that will be covered are:
- Factor data types
- Variable labelling, renaming and dropping
- Control structures useful for data cleaning.
- Reading MS Excel files into R
- Creating categorical variables for analysis
- Recoding free text descriptions into numbers
- Merging different datasets horizontally and vertically
- Changing the structure of a dataset for different statistical methods.
