STAT200 - Assignment #2: Descriptive Statistics Analysis and Writeup
Identifying Information
Student (Full Name): Hemphill, Brian D
Class: Introduction to Statistics
Instructor: Joon Yoo
Date: 02/27/2021
Introduction:
Table 1. Variables Selected for the Analysis
Variable Name in the Data Set Description Type of Variable
(See the data dictionary for describing the (Qualitative or
variables.) Quantitative)
Variable 1: “Income” 100,097.00 USD Quantitative
Variable 2: “Expenditure” 17,808.00 Quantitative
Variable 3: “Housing” 12,408.00 Quantitative
Variable 4: “Age of Head of 37 Quantitative
Household”
Variable 5: “Family Size” 3 Quantitative
Data Set Description and Method Used for Analysis:
Above is the data set I chose to use. All of these numbers are pretty close to my actual number in real
life. I wanted to see how I stack up against the data give. I used Excel to complete my work and will
attach the work with the assignment.
Results:
Variable 1: Income
Numerical Summary.

Description of Findings.
Using Excel I highlighted the cells with income and used the equation for Standard Deviation;
it can me the SD= 5866.01. I also sorted the numbers from least to greatest and did the
Median equation for 15 and 16; giving me 97,198.50. The findings for this Variable is that my
income is above the middle number.
Variable 2: (Expenditure)
Numerical Summary.
