This repository contains the script run_analysis.R that combines the data from multiple files of the Human Activity Recognition data set into a single tidy data set.

The full description and the data can be found here.

The script

1. Merges the training and the test sets to create one data set.
2. Extracts only the measurements on the mean and standard deviation for each measurement.
3. Uses descriptive activity names to name the activities in the data set
4. Appropriately labels the data set with descriptive variable names.
5. From the data set in step 4, creates a second, independent tidy data set with the average of each variable for each activity and each subject.
