Introduction:
Use the same scenario you submitted for the first assignment with modifications using your
instructor’s feedback, if needed. Include Table 1: Variables Selected for the Analysis you used in
Assignment #1 to show the variables you selected for analysis.

Data Set Description and Method Used for Analysis:
The sample data set comprises of information on 30 households with regards to certain
socioeconomic variables and expenditure variables. The given data is secondary and not primary
as it has been obtained from another source which conducted the survey. Besides, there are four
socioeconomic variables (i.e. Marital Status, Income, Age of Household Head and Family Size)
and four expenditure variable (i.e. Annual expenditure, Housing, Electricity & Water). While
most of these variable are quantitative, there is one qualitative variable in the form of marital
status.
Descriptive statistics was sued for analysis where measures of central tendency such as mean and
median were used. Standard deviation was used as a measure of variation to explain the
variations in the dataset.

Graph and/or Table: Histogram of Income
Description of Findings.
The median income was found to be 96907 with a standard deviation of 5516.57. This shows that
the data on the income is widely spread out. The histogram for the income showed that the data
is not normally distributed but rather skewed to the right.
