Examples of Data Analysis Reports

Introduction

Recently, I have discovered some old examples of data analyses, which were carried out for study purposes by my colleagues and me in 2013, during the Data Analysis course on Coursera. These examples are based on the analyses conducted on two datasets – Lending Club company dataset and Samsung smartphones dataset. The examples DO NOT contain advanced approaches to Data Analysis and Data Mining, but they will come in handy to everyone who need to see how a decent data analysis report should look like.

But remember: the following data analysis reports were composed to be read by persons at least acquanted with standard approaches to data analysis and predictive modeling.

Business-driven data analysis for non-technical people (such as managers) should be composed in other way:

  1. with much less or no (if possible) technical details,
  2. thorough yet simple description of what did you do and why did you do so
  3. clear practical recommendations, which can be directly applied to business.

If you still want to continue, you’re welcome! If not – you’re still welcome!

Lending Club dataset

According to Wikipedia, Lending Club is a US peer to peer lending company, headquartered in San Francisco, California. It was the first peer-to-peer lender to register its offerings as securities with the Securities and Exchange Commission (SEC), and to offer loan trading on a secondary market. The dataset consists of loans issued through the certain time period, including the current loan status (Current, Late, Fully Paid, etc.) and latest payment information including scoring results for a recipient of a loan.

If you’d like to try the dataset yourself, you may download it from here.

The two different examples may be downloaded from the links below (the first file is .pdf, the second one is .rtf):

Samsung smartphones dataset

Samsung smartphones dataset was obtained by Jorge L. Reyes-Ortiz, Davide Anguita, Alessandro Ghio and Luca Oneto (thank you, guys) in Università degli Studi di Genova. The dataset consists of observations of experiments, which were carried out with a group of 30 volunteers within an age bracket of 19-48 years. Each person performed six activities (walking, walking upstairs, walking downstairs, sitting, standing, laying) wearing a smartphone (Samsung Galaxy S II) on the waist. The dataset is not very large (10299 instances) and actually consists of the preprocessed sensor signals.

If you’d like to try the dataset yourself, you may download it from here. The dataset description and introduction may be found here.
