Getting_and_Cleaning_Data_Assignment
This is a peer-graded assignment for Getting and Cleaning Data in Coursera
The purpose of this project is to demonstrate your ability to collect, work with, and clean a data set.
You should create one R script called run_analysis.R that does the following:-
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 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.
About my R script
This file containing the R Script does the following steps in order to create a tidy dataset:-
1 Download the zip file
2 Unzip and extract the files
3 Assign all data frames
4 Assigning Column names for the datas
5 Let's merge the training and the test sets to create one data set.
6 Extracts only the measurements on the mean and standard deviation for each measurement.
7 Uses descriptive activity names to name the activities in the data set
8 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.
