Answer 1

Variable 1:- Income

Median = 96681USD, Mean = 99861 USD Standard deviation = 6291USD

Discreption:- 50% of the families have income less than 96681 USD, and the variation of income is more among the families.

Variable 2:- Marital status

Mode = most repeated observation since both married and single are 15 observations hence the mode is both not married and married

Variable 3: Family Size

Mean = 3.067 Variance = 1.513

On an average each family consists of 3 members with a standard deviation of 1.23.

Variable 4: Housing:-

Overall

For single

Mean = 18514.67, Variance = 17917.1

For Married

Mean = 23943.2 , Variance = 2881666

Variable 5: Food:-

Overall

Mean = 8614 , Variance = 3164841

For single

Mean = 7017.667, Variance = 6494.238

For Married

Mean = 10210.53, Variance = 1086796
