Task 1:

Organize your sample data in a spreadsheet.

Please follow instruction above!

Do you think it is necessary to use 50 samples (n=50) in order to represent the whole population of household (N=1000)? Why don't we just use 5 or 10 samples?

Task 2:

Plot the 50 sample points of WI and WEF values that you obtained in 1 on a scatter diagram. (Plot WI values along the X-axis and WEF values along the Y-axis.

Do you think putting W1 at X-axis and WEF at Y-axis seem a reasonable suggestion? Explain!

Task 3

Develop a suitable tabular form and graphical bar charts of the HLE, G, FS and frequency.

Task 4

Determine estimates of the median, mode, mean of WEF, WI and FS of WEF, WI and FS.

Is there any of your median is greater and / or smaller than mean? What does that indicate?

Is there any of your median is equal with mean? If yes, what do you think is the reason of it? If no, what do you think is the reason of it?

Task 5

Determine estimates of range, 1st & the 3rd Quartiles or (25th & 75th percentiles), Inter Quartile Range (IQR) of WEF, WI and FS.

Explain the differences and similarities of range and IQR?

Which one (either, Range or IQR) is more useful in order to compare these variables (WEF, WI, and FS)? Why?

Task 6

Determine estimates of the standard deviation (SD), variance and coefficient of variation (CV) of WEF, WI and FS.

Explain the differences and similarities of SD and CV?

Which one (either, SD or CV) is more useful in order to compare those variables (WEF, WI, and FS)? Why?

Task 7

Write a non-technical report interpreting your descriptive statistics, tabular and Graphic results obtained from Task 3 to 6, and parts in light of sample report given below (See sample report writing). Avoid repeating exact sample report wording. Present this report as the main body of this assignment. (Write in less than 300 words)
