##Summary Training and test Data sets obtained from http://archive.ics.uci.edu/ml/datasets/Human+Activity+Recognition+Using+Smartphones were merged and subsetted by desired feature measurements (mean or standard deviation). Averages for each activity performed by subjects were collected and written to final.txt.

##Definitions subject(numeric id of subject)

###Activities activity(name of activity performed by subject)

• WALKING
• WALKING_UPSTAIRS
• WALKING_DOWNSTAIRS
