The objective of the project is to generate a tidy data set from the source data with steps below:
1.Merge train and test sets.
2.Extract only the measurements on the mean and standard deviation.
3.Use descriptive activity names to name the activities in the data set.
4.Appropriately label data set with descriptive variable names.
5.From the data set in step 4, create an independent tidy data set with the average of each variable for each activity and each subject.
Source data is downloaded and uncompressed to the same folder as the script.
Resulting tidy data set is created in the same folder mentioned above.
