Numbers can be manipulated — just like words

Data can be qualitative as well as quantitative

Callout: Is the word data singular or plural?

Is this book for me?

Summary

  • Exercise 1.1: Reframing statistics


Chapter 2: Telling a Story with Quantitative Data

Data visualizations and words work together to tell a story

Not all stories are equally credible and ethical

  • Avoid breaking common conventions for reporting data
  • Do not make small differences seem large
    • For Discussion: Adjusted y-axis

Chapter 3: Visualizing Your Data Story: Part I

The most common visualizations (and the stories they support)

  • Callout: Chart, graph, figure? What’s the difference?

Bar graphs

  • Line graphs
  • Pie graphs
  • Tables

The case against pie graphs: Why they should be used sparingly

Chapter 9: Writing about Methods

Methods readers lie at two extremes of care in reading

Methods are typically organized with subheadings

Methods sections justify choices

  • For Discussion: Justifying methodological choices

Methods sections favor past tense and passive voice

  • Exercise 9.1: Choosing active or passive voice

Methods themselves are sometimes a major research contribution

Summary

What goes in the Discussion versus the Conclusion?

A Recommendations section often concludes business and professional reports

Summary

  • Exercise 11.3: Annotating concluding sections


Chapter 12: Front Matter: Titles, Abstracts, and Executive Summaries

Titles should clearly and precisely state the main focus

Abstracts and executive summaries are reports in miniature

The traditional academic abstract is a single paragraph

The structured academic abstract has labeled sections

An IMRD executive summary is typically one page

The recommendations-first executive summary

Avoid common problems with executive summaries

Summary

  • Exercise 12.1: Rating abstracts
