TidyDataProject

This repo contains an R script and associated files to create a tidy data set from the original accelerometer dataset linked in the course project.

The original dataset can be downloaded from here: https://d396qusza40orc.cloudfront.net/getdata%2Fprojectfiles%2FUCI%20HAR%20Dataset.zip

The repo has the following files-

run_analysis.R

• R script to create the tidy data set from the original data according to this recipe

1. Merges the training and the test sets to create one data set.
2. Extracts only the measurements on the mean and standard deviation for each measurement.
3. Uses descriptive activity names to name the activities in the data set.
4. Appropriately labels the data set with descriptive variable names.
5. Creates a second, independent tidy data set with the average of each variable for each activity and each subject.

• To run, download the original dataset and run the run_analysis.R script from the parent directory (that has the getdata_projectfiles_UCI HAR Dataset/ directory).
• The script will write the tidy dataset to tidy_means_std_avg.txt
