Exactly. 38% is way too high. Are we sure about that? Statistics is not some required learning in school. Even those who learned (me for example) cannot confidently claim what it actually means. I would say most of the people don't have a clue what statistics mean

Here in Norway, statistics has been introduced in 9th and 10th grade (15 and 16 year olds). Here[1] is what a 9th grader is supposed to know at the end of the school year. Some key points translated to English:

- Interpret and critically evaluate statistical representations from the media and the local community.

- Calculate measures of central tendency and measures of dispersion in custom and real datasets, and use the results to describe the data.

- Calculate and evaluate probability in statistics and games.

This came after my time, and our PIRSA score aren't the best so perhaps practice is lacking.

We are just as bad or worse with charts. I don’t know whether finding Tufte when I was still relatively young saved or harmed my sanity. Maybe both. Everyone’s charts are awful, including at least half of mine, and I was trying to be objective. Many people are just trying to prove a theory they had before the chart was made.

If you changed "most" to "all" you'd be well inside the margin or error.

There's a reason actuaries get paid the big bucks.
