For my third course, I am taking DTSC 560 Data Science for Business. It’s the third course on utilizing the programming language R with Excel added on.
✍🏿 Here’s a description of the course:
This course explores the various ways data and science can be applied to business contexts. Particular emphasis will be placed on decision using data to make informed business decisions.
This course will actually have 5 homework assignments, 5 quizzes, and 2 exams.
In this course, you should have some previous experience with both Excel and R, enough to conduct basic-to-intermediate analyses. This course does not include an introduction to using Excel or R - we will immediately use both applications for specific analyses and it will be difficult to follow along or succeed in the course without some familiarity with both
The book we are using is Camm, J.D., Cochran, J.J., Fry, M.J., & Ohlmann, J.W., (2021). Business Analytics, 4th Edition. Cengage. and located here.
The course uses R and Excel.
💡 Learning Objectives
- Define predictive data mining and cluster analysis
- Execute a k-means cluster analysis in R
- Execute a hierarchical cluster analysis in R
- Interpret cluster analysis results
💪🏿 This is what I accomplished my second week in the DTSC 560 course:
📘 Chapter 5, only Section 5.1. Cluster Analysis
📺 Videos Watched (each video has a 1 question quiz at the end)::
- What is Descriptive Data Mining?
- What is Cluster Analysis?
- Cluster Analysis Dataset
- Dissimilarity Measures for Numerical Variable Values
- Similarity Measures for Categorical Variable Values
- K- Means Clustering
- K-Means Clustering Example in R
- Interpreting Clusters from K-Means Cluster Analysis
- Hierarchical Clustering
- Hierarchical Clustering Example in R
- Interpreting Clusters from Hierarchical Cluster Analysis
- K- Means VS. Hierarchical Clustering
🧪 Homework
- Conduct both a k-means and a hierarchical cluster analysis in R, using the same variables for each to compare the outcomes. I will use this assignment to answer questions from the quiz.
💯 Quiz
- In this class, you are only given 3 chances to take the quiz and get it right. A few fill in the blank questions, multiple choice, and more than one answer questions.
- I only have 3 attempts for each quiz and exam. I took the exam 3 times. Final score was 93.33% where I missed one question. You have until the end of the semester to take all your exams.
