Reading Response 2: Data Wrangling

INSTRUCTIONS

When complete, DELETE these instructions and the enclosing box and submit your completed response with just the questions and your answers.

Place your first and last name in the appropriate place in the header above.

Then, for each concept listed below:

  1. Conduct a web search to find one or more credible sources that help you define it and answer the related questions.
    • NOTE 1: There are many high-quality data- and tech-related resources on the web. The concepts and questions below are frequently discussed on the web, and so answers will not be difficult to find. Over time as you do this work, you’ll identify several credible sources that you can frequently return to.
    • NOTE 2: IN MY CLASS, for these assignments — which are not formal essays but developing general knowledge — Wikipedia counts as a credible source. Wikipedia is often a trustworthy source for tech-related fields.
  2. Using your research skills, read to understand each concept – not only definitions, but examples that illustrate what they mean – until you understand it. Then WRITE YOUR OWN ANSWER to each question. Do not copy and paste use full-sentence quotations from your sources. Your answers should PARAPHRASE your sources, using a few key words but not copying whole sentences. The point of this assignment is to get you to read, think, and process these concepts until you understand them. Canvas makes it easy for me to see when you have used entire sentences from sources, and I will grade you down for it.
  3. At the end of each answer, provide a title and link to the sources you used.
  4. Format the entire document well, so that it looks organized and professional.
  5. DO YOUR OWN WORK. Do not turn in anyone else’s document as your own. Do not copy significant portions of someone else’s document. (Again, Canvas tells me when this happens.)

When complete, DELETE these instructions and the enclosing box and submit your completed response with just the questions and your answers.

As always, be sure to provide a title and link to your sources.
