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. In the subsequent section, explain why you selected each variable as well as the expected outcome.

Table 1. Variables Selected for the Analysis

Variable Name in the Data Set	Description (See the data dictionary for describing the variables.)	Type of Variable (Qualitative or Quantitative)
Variable 1: “Income”	Annual household income in USD.	Quantitative
Variable 2:
Variable 3:
Variable 4:
Variable 5:

Reason(s) for Selecting the Variables and Expected Outcome(s):

1. Variable 1: “Income” -

2. Variable 2: “ “ -

3. Variable 3: “ “ -

4. Variable 4: “ “ -

5. Variable 5: “ “ -

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

Variable Name	Measures of Central Tendency and Dispersion	Rationale for Why Appropriate
Variable 1: “Income”	· Median · Sample Standard Deviation	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.
Variable 2:
Variable 3:
Variable 4:
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. Note: Do NOT simply copy this for the remaining quantitative variables. Make a logical selection based on the data type.

Table 3. Type of Graphs and/or Tables for Selected Variables

Variable Name	Graph and/or Table	Rationale for why Appropriate?
Variable 1: “Income”	Graph: Histogram	A histogram is one of the best plots available to visually depict the distribution of quantitative level data.
Variable 2:
Variable 3:
Variable 4:
Variable 5:
