Purpose

The purpose of this course is to introduce practitioners to a work process that integrates all components of work into one platform. This is not merely “using rMarkdown” – this is a broader philosophy of work. For example, reproducible research standards and principles are facilitated by adopting literate programming into work processes, but reproducibility (e.g., Stodden, Leisch, and Peng 2014) is only one of many derivatives of literate programming.

This syllabus, for example, showcases a few pedagogical enhancements:

  • External resources and opportunities for feedback are accessible via links in the upper right-hand toolbar.
  • Annotation and note-taking capabilities are enabled (via hypothesis) and accessed via floating icons located in the far upper-right sidebar of the browser window.
  • Screen reader functionality is enabled by default (screen-readers will pick up alternative text descriptions that are provided for each image).

These are just a few of very many latent features (quite easily) accessible when employing literate programming practices – and we haven’t even discussed anything “analytical” yet…

The next few pages showcase some additional capabilities currently available within literate programming platforms that may further entice a data scientist practitioner to adopt literate programming principles.

For additional encouragement regarding literate programming adoption, please see our customer sales rep pictured in Figure 1.

Practice Math Questions: Principles of Economics

The following 20 practice questions are aimed at undergraduate students in introductory economics. Some are multiple-choice; others are numeric-response problems that are generated with random numbers each time the page loads. For numeric questions, enter your answer and click Check.

Multiple choice (pick the best answer)

  1. If the price of a good increases from $10 to $12 and quantity demanded falls from 100 to 80, the arc price elasticity of demand (absolute value) is approximately:
  • A. 0.5
  • B. 1.0
  • C. 1.5
  • D. 2.0
  1. If a firm’s total cost is $200 when output is 10 and $260 when output is 20, the average cost at output 20 is:
