#CodeBook
This CodeBook describes data that contained in tidy.txt file
File contains averaged data of measurements that taken from the merged raw test and train datasets of "Human Activity Recognition Using Smartphones Dataset"
Version 1.0 - http://archive.ics.uci.edu/ml/datasets/Human+Activity+Recognition+Using+Smartphones
#Initial Data Collection
Initial dataset was downloaded from https://d396qusza40orc.cloudfront.net/getdata%2Fprojectfiles%2FUCI%20HAR%20Dataset.zip
#Filtering initial data
Only features that contains "mean" and "standard deviation" of raw measurements was used for production of a new tidy dataset
#Processing
Test and Train part of the filtered initial dataset were merged together for production of tidy dataset.
Labels of activities were used instead of activity ids.
Final dataset contains measurements averaged per subject per activity.
#Identifiers "subject" - id of subject "activity" - label of activity - one of WALKING WALKING_UPSTAIRS WALKING_DOWNSTAIRS SITTING STANDING LAYING
