Hypotheses

Journalistic hypotheses: not quite to the rigor of scientific hypothesis, but you similarly want to always ask “how might this not be true?”

Identify the different elements that you want to quantify as part of your hypothesis with the data.

  • Problem: Typhoons across the region are causing extensive damage

  • Impact: Disproportionate climate effects including death, displacement, and economic loss by region and by regional level of vulnerability

  • Cause: Per capita budget allocation and utilization for disaster relief and management. Road conditions.

  • Solution: Investment proportional to identified vulnerability and need.

Put it all together in a hypothesis draft: Typhoons have caused more death, infrastructure damage, displacement, and destruction in the Philippines in the last 10 years than in any other island country in the region, with a disproportionate impact in vulnerable areas that are more likely to have lower rates of investment in disaster management and relief as well as fewer and poorer quality roads

Start to draft your hypothesis

10 mins on your own, then 10 mins with your group

Tasks before next week

  • Reading to be announced - will send an email via Canvas

  • NO coding notebook

  • Story-based checkpoint:

    • Draft elements of hypothesis and then write a hypothesis

    • Add a section to your Masterfile: make a table with three columns. The first column will be your hypothesis elements: a row each for problem, impact, cause and solution. Write them out. In the second column, list at least one dataset or other source of evidence that will help you prove/disprove that element. And in the third column, write any questions, uncertainties, confusions, or other comments about that element or how you might move forward on it.
