Files

  • CodeBook.md a code book that describes the variables, the data, and any transformations or work that I performed to clean up the data

  • run_analysis.R performs the data preparation and then followed by the 5 steps required as described in the course project’s definition:

    • 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.
  • Data_final.txt is the final data exported into file text. This file corresponds to an average of each variable for each activity.
