Present a finding with its range and its limits

short · 35 min · Objective 3.1

Task

Write up the survey's mean satisfaction as a short report that gives a range rather than a single figure, states what the data cannot show, and makes one recommendation that follows from it.

Steps

  1. Use the 95% interval you calculated in the sampling lab, 3.39 to 3.76, or calculate it again.
  2. Write lab/present/report.md with the headings ## Finding, ## Range, ## Limitations and ## Recommendation.
  3. Under Range, give the interval in the form 3.39 to 3.76.
  4. Under Limitations, name at least one reason the respondents may not represent all customers.

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.

grep -cE '^## (Finding|Range|Limitations|Recommendation)' lab/present/report.md
grep -c '3.39 to 3.76' lab/present/report.md
grep -ciE 'respon|represent|bias' lab/present/report.md

Four sections, the interval stated as a range, and a limitation about who answered. A report that said "satisfaction is 3.575" would be more precise-looking and less true.
