-
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, and the result is shown in
MeanData.txt.
