Learn how to calculate descriptive statistical metrics in order to describe a dataset in basic R
Create a data quality report file (exported to Excel in CSV format) from a dataset loaded in R
By the end of this project, you will create a data quality report file (exported to Excel in CSV format) from a dataset loaded in R, a free, open-source program that you can download. You will learn how to use the following descriptive statistical metrics in order to describe a dataset and how to calculate them in basic R with no additional libraries. - minimum value - maximum value - average value - standard deviation - total number of values - missing values - unique values - data types You will then learn how to record the statistical metrics for each column of a dataset using a custom function created by you in R. The output of the function will be a ready-to-use data quality report. Finally, you will learn how to export this report to an external file. A data quality report can be used to identify outliers, missing values, data types, anomalies, etc. that are present in your dataset. This is the first step to understand your dataset and let you plan what pre-processing steps are required to make your dataset ready for analysis. Note: This course works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions.
Data Quality
Statistics
R Programming
In a video that plays in a split-screen with your work area, your instructor will walk you through these steps:
Load and view a real-world dataset in RStudio
Calculate “Measure of Frequency” metrics
Calculate “Measure of Central Tendency” metrics
Calculate “Measure of Dispersion” metrics
Use R’s in-built functions for additional data quality metrics
Create a custom R function to calculate descriptive statistics on any given dataset
Export the results of the descriptive statistics to a data quality report file
