The input data required to run this script can be found here.
The goal of the run_analysis.R script is to accomplish the following.
- Merges the training and the test sets to create one data set.
- Extracts only the measurements on the mean and standard deviation for each measurement.
- Uses descriptive activity names to name the activities in the data set
- Appropriately labels the data set with descriptive variable names.
- 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.
The tidy dataset is writed to a file (tidy_data_output.txt) in the same directory of the script.
