Course Project for "Getting and Cleaning Data"
This script does the following.
- It merges the training and the test sets to create one data set.
- Extracts the measurements on the mean and standard deviation for each measurement.
- Adds descriptive activity names to name the activities in the data set
- Then writes a tidy data set with the average of each variable for each activity and each subject to a file.
