Dear Teachers,
I read this from The Next Thing on My List by Jill Smolinski:
"I've had eight boyfriends so far in my life, with the average length of relationship being 9.8 months. The mean is 14.4 months."
What does "the mean" refers to?
Hello,
Note I'm not a teacher,
Sorry marciobarbalho but I don't agree with you.
That is the median not the mean; and a median isn't (always) equals a mean.quantity having a value intermediate between the values of other quantities
An average is interchangeable with a mean. The context doesn't change that;
So here it must be used for different meaning becouse average(mean) is 9.8 and the mean(average) is 14.4.
That doesn't really make sense ...
I think it's word game; as mean means as well very good or not generous.
Cheers,
See this recent thread about mean and median:
https://www.usingenglish.com/forum/a...17-median.html
the mean number is the product of a collection of numbers added together and then divided by the amount of numbers.
For instance
3 + 7 + 2 + 9 = 21
21/4 = 5
So the author has taken the 8 different amounts of time (of each relationship) added them together, and divided them by 8 (the amount of relationships).

Hello,
Note I'm not a teacher,
It seems that "the average length of relationship" refers to the median and "the mean" to the mean.
That make sense .. but at first sight it wasn't so obvious.
But how can one know which an average value the author meant by average length of
Is it common to refer to a middle value or a median as an averege value ??
or it is a mistake ?
Cheers,
