STAT200 - Assignment #1: Descriptive Statistics Data Analysis Plan Identifying Information
Student (Full Name): Yesenia Vasquez Martinez

Scenario: Please write a few lines describing your scenario and the four variables (in addition to income)
you have selected.
Use Table 1 to report the variables selected for this assignment. Note: The information for the required
variable, “Income,” has already been completed and can be used as a guide for completing information
on the remaining variables.
Table 1. Variables Selected for the Analysis
Variable Name in the Data
Set Variable 1: “Income” Description
(See the data dictionary for describing the
variables.)
Annual household income in USD. Variable 2: Type of Variable
(Qualitative or
Quantitative)
Quantitative Quantitative
Total Amount of Annual Expenditure on Food Variable 3:
Variable 4:
Marital Status of Head of Household
Variable 5: Qualitative
Quantitative Reason(s) for Selecting the Variables and Expected Outcome(s):
1. Variable 1: “Income” -Income is the upper limit of the budget to be determined, therefore, it is an important factor in helping the household establish the budget accordingly.
The higher the income, the higher the planned budget will be, and the lower income will
restrict the budget. STAT200: Assignment #1 - Descriptive Statistics Analysis Plan - Template
Page 1 of 3 2. Variable 2: “Food “- Food is an essential expense and a budget cannot be completed without including the expense related to this factor. Therefore, food becomes an essential part
of budget planning for each household
3. Variable 3: “ “ - 4. Variable 4: “Marital status “ -The marital status of the head of the family allows us to know the routine expenses. A married head has higher expenses compared to a single person.
Therefore, it is one of the prerequisite factors that affect family budget planning.
5. Variable 5: “Family size “-The purpose of the data is to plan the budget for the home. More family members would be more expenses, therefore it is important to know the number
of family members. Data Set Description:
Proposed Data Analysis:
Measures of Central Tendency and Dispersion
Complete Table 2. Numerical Summaries of the Selected Variables and briefly explain why you choose
those measurements. Note: The information for the required variable, “Income,” has already been
completed and can be used as a guide for completing information on the remaining variables. Table 2. Numerical Summaries of the Selected Variables

● Number of
Observations
Median
Sample Standard
Deviation Rationale for Why Appropriate I am using median for two reasons:
1. If there are any outliers or the data is not normally
distributed, the median is the best measure of
central tendency.
2. The variable is quantitative.
I am using sample standard deviation for three reasons:
1. The data is a sample from a larger data set.
2. It is the most commonly used measure of
dispersion.
3. The variable is quantitative. STAT200: Assignment #1 - Descriptive Statistics Analysis Plan - Template

Variable 5: Graphs and/or Tables
Complete Table 3. Type of Graphs and/or Table for Selected Variables and briefly explain why you
choose those graphs and/or tables. Note: The information for the required variable, “Income,” has
already been completed and can be used as a guide for completing information on the remaining
variables.

“Income” Graph: I will use the histogram to
show the normal distribution of data. Histogram is one of the best plot to show the
normal distribution of quantitative level data . Variable 2:

STAT200 Introduction to Statistics
Dataset for Written Assignments
Description of Dataset:
The data is a random sample from the US Department of Labor’s 2016 Consumer Expenditure Surveys (CE) and provides information about the
composition of households and their annual expenditures (https://www.bls.gov/cex/). It contains information from 30 households, where a survey
responder provided the requested information; it is all self-reported information. This dataset contains four socioeconomic variables (whose names start
with SE) and four expenditure variables (whose names start with USD).
Description of Variables/Data Dictionary:
The following table is a data dictionary that describes the variables and their locations in this dataset (Note: Dataset is on second page of this document):

us that: the head of household is not married and is 39 years old, has an annual household income of \$96,727, a family size of 2, annual food
expenditures of \$7,051, and spends \$904 on meat, \$345 on bakery items, and \$759 on fruit. UniqueID# SE-MaritalStatus SE-Income SE-AgeHeadHousehold SE-FamilySize USD-Food USD-Meat USD-Bakery USD-Fruits 1
