8.6 Assignment  Lecture 8In this assignment you will experiment with data preparation and plotting in foresight of simple statistical analysis.8.6.1 Part A  IndividualIn this part, you will graph statistics about disabilities in a given country. The dataset is unprepared and needs to be manually entered and formatted in a spreadsheet. Once entered, you will import the dataset in Matlab and perform a series of plotting commands to better visualize the data.1. Download the following PDF, taken from the United Nations Statistics Division . This file includes data on number of persons with disabilities, divided into age groups and gender. Note that age groups vary between countries. All countries have a table that summarizes the total number of disabilities. Sometimes, additional tables are presented for rural versus urban regions. You will ONLY use the table for total number of disabilities, and disregard the additional ones. Each table for both sexe, number of male, and number of female persons contains data on total population in a given age group, total number of persons with disabilities in that age group, and number of persons with disabilities per one thousand. For some countries one or the other column may be missing  this will not impact the assignment.
3. Import the dataset in Matlab. You should end up with one vector for row headers, one vector for column headers, and one numerical matrix for values. 4. Using Matlab, compute the missing columns. Use whatever methods necessary to perform this step, but you must end up with a full matrix of 9 columns, which include the data from all three original tables. Be sure to modify the column header vector to reflect the change in columns. 5. Using a 3row, 2column subplot, plot the following 6 graphs. I would suggest first doing this without subplot, and simply plotting each graph in the same window. When you are confident about your final answers, you can add the subplot command to each plot. For all plots, be sure to include proper titles, xlabels, ylabels. Include legends only when specified. Graphs:
8.6.2 Part B  Group ComponentPart of your final project for this course, you (your team) will be required to perform some statistical analysis related to your Community Service Learning project. You are free to choose any aspect, but make sure that this aspect conveys some meaningful information.For example, if your project deals with designing a playground for disabled children, it may be helpful to know some of the following:
While this is just an example, your team should figure out what kind of analysis is realistic and possible. For the group portion of this assignment, you and your team members should find a problem and the necessary data that you would like to address for your final presentation. One significant constraint is obviously finding appropriate data for your specific problem. You will have to dig deep into the Internet, perhaps ask your clients, or call up agencies that may have this kind of information. You can use the online resources mentioned in this lecture. 8.6.3 Part C  Individual ComponentAfter your team has gathered the necessary data, each team member should individually load the data into Matlab, either using the import wizzard or some command line function. Then, pick several (23) aspects of the data and plot them. You can use the examples in Part A for some guidance. Make sure that your plots contains proper labels and titles. Place all plots in a subplot grid of appropriate size.For example: Your team has downloaded a data set that evaluates the number of disabled children for different ages, different time periods, different regions, different household income levels, etc. You are now required to import this text database into Matlab. Pick several data pairs, e.g. time period versus number of disabled children, and plot this data using Matlab.
