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.

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.

Rationale for Why Appropriate |
|
Variable 1: “Income”
|
· ● Number of Observations · ● Median · ● Sample Standard Deviation |
I am using median for two reasons: 1. 1. If there are any outliers or the data is not normally distributed, the median is the best measure of central tendency. 2. 2. The variable is quantitative.
I am using sample standard deviation for three reasons: 1. 1. The data is a sample from a larger data set. 2. 2. It is the most commonly used measure of dispersion. 3. 3. The variable is quantitative.

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.

Graph and/or Table |
Rationale for why Appropriate? |
|
Variable 1: “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 . |
