Unsupervised Data Mining
In this assignment, you will learn how to apply three unsupervised data mining techniques using
country-level health and population measures data and social media usage patterns data.
Prompt:
For this assignment, you will analyze the three case studies below and address the questions associated
with each.
For all cases, first partition data sets into 50% training, 30% validation, and 20% test and use 12345 as the default random seed. If the predictor variable values are in the character format, then treat the predictor
variable as a categorical variable. Otherwise, treat the predictor variable as a numerical variable.
Case 1:
For this case, first download the data: Health Population data (available in Blackboard).
Next review the following case study:
The data set Health Population contains country-level health and population measures for 38 countries from
the World Bank’s 2000 Health Nutrition and Population Statistics database. For each country, the measures
include death rates per 1,000 people (Death Rate, %), health expenditure per capita (Health Expend, in
US$), life expectancy at birth (Life Exp, in years), male adult mortality rate per 1,000 male adults (Male
Mortality), female adult mortality rate per 1,000 female adults (Female Mortality), annual population growth
(Population Growth, in %), female population (Female Pop, in %), male population (Male Pop, in %), total
population (Total Pop), size of labor force (Labor Force), births per woman (Fertility Rate), birth rate per
1,000 people (Birth Rate), and gross national income per capita (GNI, in US$).
Then complete the actions below and record your answers in a Microsoft Word document.
Note: For step-by-step instructions on how to use Excel and Analytic Solver to estimate and predict with
both clustering methods and how to interpret results, refer to the following videos from the module’s lesson:
● Hierarchical Cluster Analysis – Introduction (5:14)
● Using Analytic Solver to Perform Agglomerative Clustering (4:42)
● Using Analytic Solver to Perform K-Means Clustering (3:15)
Section 1: Hierarchical Clustering:
1. Perform agglomerative clustering to group 38 countries according to their health measures listed
below. Use the Euclidean distance and the average linkage clustering method (Group average
linkage) to cluster the data into three clusters. Is data standardization necessary in this case?
Explain.
Use the following measures only: Death Rate, Health Expend, Life Exp, Male Mortality, and

2. Report the size and the average GNI per capita of each group.
Section 2: K-Means Clustering:
3. Perform K-Means clustering to group 38 countries according to their health measures listed below to cluster the data into three clusters. Is data standardization necessary in this case? Explain.
Use the following measures only: Death Rate, Health Expend, Life Exp, Male Mortality, and
Female Mortality, Fertility Rate and Birth Rate

4. Describe the characteristics of each cluster by comparing the averages of GNI per capita,
Population Growth, Labor Force, Fertility Rate and Birth Rate of each group and report your findings
in a table.
Case 2:
For this case, first download the data: Social Media Usage data (available in Blackboard).
Next review the following case study:
Adrian Brown is a researcher studying social media usage patterns. In his research, he noticed that people
tend to use multiple social media applications, and he wants to find out which popular social media
applications are often used together by the same user. He surveyed 100 users about which social media
applications they use on a regular basis.
Then complete the actions below and record your answers in a Microsoft Word document.
Note: For step-by-step instructions on how to use Excel and Analytic Solver to estimate and predict with
association rule and how to interpret results, refer to the following videos from the module’s lesson:
● Association Rule Analysis (9:11)
● Using Analytic Solver to Perform Association Rule Analysis (3”41)

1. When you select the data ignore User ID and select the data with labels. Do not forget to select
“First Row Contains Headers” option. Generate association rules with a minimum support of 20
and minimum confidence of 60%. How many rules are generated?
2. Sort the rules by lift ratio. What is the top rule? Report and interpret the lift ratio of the top rule.
Submission Guidelines:
Your completed assignment must be submitted as a Microsoft Word document, 1-2 pages in length, double spacing, 12-point Times New Roman font, and 1-inch margins. The submission must be accompanied by three Microsoft Excel spreadsheets showing your work. Only the Word document will be assessed for
grading purposes, however the case spreadsheets are required and must be submitted to show your work.
Note: No tables or charts need to be included in your Word document for this assignment.
Note About Grading:
This assignment will be assessed based on the accuracy of your responses to each question in the
worksheet.
