Assignment: Analysing Household Data
Background: Have you been part of a national census? Privacy issues aside, a census is a complete enumeration which provides lots of data that can inform a government policies and actions - but to be useful, the data needs to be summarised (tabular or graphic form), analysed and interpreted. In this assignment, we will use statistical methods to summarise, analyse and interpret real world demographic data.
Objective: The objective of this assignment is to
- Test your understanding of statistical methods and approaches
- Improve your ability to use Excel for manipulation of data
- Interpret the statistical results
- Understand the real-world applications and implications of statistics
To complete this assignment you must
- Complete a set of statistical analyses tasks on a unique data set available on LMS.
- Submit in a report in word detailing your response to each task (the final answer and reasoning /calculations that led to it)
- Submit an excel document that contains your data set and the calculations you used to complete the tasks
Instructions: Analysing Household Data
In this assignment you will be analysing and interpreting household data
Step 1: Prepare Data Set
- Download Excel Data file Data_Assignment01 from LMS. Once you download this file, enter your Student ID in the space provided as shown in the picture below.
- You will need to know how to manipulate data in Excel. You can use any other compatible spreadsheet tool (for example Numbers for Mac OS, OpenOffice, LibreOffice etc) but be aware that some of the functions differ slightly.
- There are plenty of resources online and in this LMS (Tutorial 02, for instance) that will show you how to perform these tasks in Excel. Use these resources (and Google) to improve your skills as you progress. If you have a particularly difficult challenge, share it in the forum and your tutors or peers will help.
Step 2: Analyse Data & Submit Report
- You will be presented with a set of tasks to run on your unique data set (of 100 samples) - the full list of tasks is provided below.
- As much as possible, complete these tasks within the excel document. You will need to submit your excel document at the end of the assignment
- You will also submit a brief report in word addressing all the tasks below. When responding to the tasks, please explain the reasoning behind your answer, and refer to your Excel sheet.
Tasks for Analysis of Data Set
Complete the following tasks based on the unique data set you generated. These questions should be answered in a Word document, with brief reasoning to justify your answers. Your answers and reasoning should correlate with the excel sheet (where applicable, make references in this document to your excel sheet)
Task 1-
A. Organize your sample data in a spreadsheet as per the instructions in the Excel sheet
B. What sampling method is used to select your sample data?
C. Do you think that is the best method of sampling? Why or why not?
D. What is the best statistic used to compare the volatility in WEF, WI, and FS values? Why?
Task 2-
A. Develop the tabular form and graphical bar chart of WI based on the following classification:
a. 1st Class = Very Poor
b. 2nd Class = Poor
c. 3rd Class = Moderate
d. 4th Class = Rich
e. 5th Class = Very Rich.
B. What is the most frequent group in your WI sample data? What does that indicate in terms of your data distribution?
C. Do you think your WI of sample data is normally distributed? Provide the "statistical reason" for your answer?
Task 3-
A. What is the top 10% and bottom 10 % of your WEF household values?
B. What is the probability that your WI values will be less than or equal to $200?
C. What is the probability that FS will be equal to 2?
D. Is there any outlier(s) in your sample data of WEF? Show the graph or prove for that! If yes, what is the best statistic to measure the disparity of your WEF?
Task 4-
A. What is the probability that a randomly selected head of a household is female and her HLE is Primary?
B. What is the probability that a randomly selected household head is male and has the College degree?
C. What is the proportion of having the Secondary as the highest degree from among males?
D. What is the proportion of having the Intermediate as the highest degree from among males?
E. Do you think that the events "gender of household head is male" and "having the CollegeDegree" are independent? Explain briefly.
