Students will review, analyse, design, implement experiments to evaluate the proposed methodology in previous assignment, and report experimental results and findings as well. Tasks: 1. Collect your data for experiment a. Identify the available data sources for collection. b. Select the most appropriate data source(s) and start data collection. You are asked to record the data sources that you have found, brief description of the available data using the following sample table: Data Source Name Source Organization Data Description Data File Format URL (if available online) Charge Fee Target data source Data 1 Sport Centre, VU Exercise training record txt http://xxxxxxx Free Yes Data 2 … … … … $1000 No c. Store the collected data in appropriate file format. You need to save the collected raw data, and keep a copy at all times. i. Create a folder called “raw data” to store the collected raw data ii. Record your data collection using the following sample table: Data Source Name Date of Collection Saved File Location Saved File Name Saved File Format No. of Data Records Data 1 15/3/2016 //raw data/ xxxx.txt txt 2000 Data 3 … … … … NIT6130 – Introduction to Research Page 2 of 3 2. Design and implement experiments a. Adopt data pre-processing. Not all the collected raw data are available as direct input of your methodology. b. Feature selection or dimension reduction. You may need to select some of data features or data records from the entire data collection, not to use all the collected data. In other case, you may need to reduce the dimensionality of the collected data to simplify the data processing in the later stages. You need to save the result data set into a new file. You are asked to record these works using the following sample table.

Design your experiment based on the proposed methodology. The main purpose of experiments is to prove that your methodology can provide expected outcomes. You can follow the experiments that you have read from literatures or any other ways that is suitable for your case. Your experiments procedure need to be detailed recorded, including instruction steps, input data, expected output, potential problems and other related issues. When state the procedure of experiment, you can use extra table, figure, chart, diagram to provide better description.

To implement your experiment, normally you need to use software/tools or write your own program. Record your experiment results for each run as the references of the following analysis task. 3. Result analysis and summary NIT6130 – Introduction to Research Page 3 of 3 a. What are the expected results that you want to obtained from the experiment? You need to have a rough idea of what you may have in advance; you cannot wait until the experiment is done. b. Plan your result analysis by thinking of what result you may have first. Write a summary of why you expected to have that results, how they can be linked to your research problems. 4. Write up your experiment and result analysis chapter. a. Provide an outline of your experiment and result analysis chapter, including up to four levels of subsections. Only need to list the chapter titles (level 1), section titles (level 2), subsection titles (level 3), and sub-subsection titles (level 4).

Before starting that our first task was to collect the data which we were going to use for experiments. Initially, we found the different sources for data collection. In section 3.1.1 we identified the sources which existed for data collection. Then we selected the most appropriate data source and started working on it section 3.1.2. Put all the data on a table for the record. In section 3.1.3 created a file and put all the data in that file and save in computer. 1.1 Data Sources Before start any experiment I had to research about the problems, design experiments and select sources from where I can collect data. I chose 3 different categories of people e.g., common people of every age, young students, and professionals. Public places(mall, parks) College or university Companies 1.2 A collection of data I made a table below to record the data sources, main organizations where I can collect the data. What type of data I collected, format, and fee and if it was appropriate for my research. Table1 Data collection Data Source Name Source Organization (public= college, mall, and company) Data Description Data File Format Charge Fee Target Data Source 6 | P a g e Data 1 Public How many users have smartphones? txt Free Yes Data 2 Public How many users aware of health fitness apps available on their mobile phones? txt Free Yes Data 3 Public How many users download free apps? txt Free Yes Data 4 Public How many follow these apps? txt Free Yes Data 5 Public How many feel these apps are effective? txt Free Yes Data 6 Public How many satisfy with results? txt Free Yes 1.3 Data Storage After creating and completing that table my next step is to collect data and put that in another table. This table contains raw data, whatever I got from people. I recorded a number of data, where I saved it. It was for my knowledge purpose so that I would not lose or forgot it.
