Lecture 27: Subsection "95% Confidence": Last Bullet Point: Confusing Phrasing (Minor) #50

Closed asheynis closed 12 months ago

asheynis commented 1 year ago

In Lecture 27, in the subsection titled "95% Confidence", the last bullet point reads as "The confidence is in the process that creates the interval: It generates a "good" interval with chance 95%" which does not make sense to me particularly in the latter part. I do not even know what alternative wording to suggest. Is it trying to say "... with a chance of 95%" or "... with a 95% chance" since it is about the reliability of getting an interval?

To my knowledge, all three options presented (the current and your two alternatives) are all equivalent. The only consensus I found is that they differ in formality/simplicity where with change 95% is the most concise version.

@amclanahan, do you have an opinion on this?

Maybe 'It generates a 'good' interval (approximately) 95% of the time.' would be a better way to say it.
