##Activity Labels
- Walking (v1): subject was walking during the test
- Walking_Upstairs (v2): subject was walking up a staircase during the test
- Walking_Downstairs (v3): subject was walking down a staircase during the test
- Sitting (v4): subject was sitting during the test
- Standing (v5): subject was standing during the test
- Laying (v6): subject was laying down during the test
##Information about the experimental study design used description of how collected the data
- Merging the training and the test sets to create one data set
- Reading training tables
- Reading testing tables
- Reading features vector
- Reading activity labels
- Assigning column names
- Merging all data in one dataset
- Subsetting the measurements on the mean and standard deviation for each measurement
- Reading column names
- Create vector for defining ID, mean and standard deviation ignoring letter case
- Making nessesary subset from the merged data
- Using descriptive activity names for the activities in the data set
- Appropriately labeling the data set with descriptive variable names
- Creating a second, independent tidy data set with the average of each variable for each activity and each subject
- Making second tidy data set
- Writing second tidy data set in txt file
