run_analysis.R - this is script is responsible to generate a tidy data from a data set, based on these steps:

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.

To run the run_analysis.R script just change the variable folderpath to the directory where you have downloaded the repository files.
