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.

โœ๐Ÿฟ 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.

๐Ÿ’ก 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

๐Ÿ’ช๐Ÿฟ This is what I accomplished my second week in the DTSC 560 course:

๐Ÿ“˜ Chapter 5, only Section 5.1. Cluster Analysis

๐Ÿ“บ 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

๐Ÿงช 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.

๐Ÿ’ฏ 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.
