Write one finding for two audiences

short · 30 min · Objective 3.1

Task

Take one result -- the gap between the mean and median order value -- and write it twice: a three-sentence summary for an executive that leads with the answer, and a note for an analyst that gives the method and the numbers.

Steps

  1. Calculate the mean and median net value of valid orders, as in the descriptive statistics lab.
  2. Write lab/audience/executive.txt: at most three sentences and 60 words, leading with the conclusion and containing one number.
  3. Write lab/audience/analyst.txt: the method, the filter applied, both figures, and the word median.

Verify

These checks run in a POSIX shell with Python 3: Terminal on macOS or Linux, and on Windows Git Bash (it comes with Git for Windows) or WSL. On Windows, python3 is often a Microsoft Store placeholder that prints “Python was not found”; run alias python3=py in Git Bash first.

wc -w < lab/audience/executive.txt
grep -o '[.!?]' lab/audience/executive.txt | wc -l
grep -c '[0-9]' lab/audience/executive.txt
grep -ci 'median' lab/audience/analyst.txt

The executive version has at most 60 words and 3 sentences, and contains a number; the analyst version names the median. The same fact -- a typical order is about 99, while a few huge ones lift the average to 178 -- serves both, told in the order each reader needs.
