I'm relatively new to featured quizzes so I'll keep these suggestions in mind and let Quizmaster help out as well with making recommended changes.
example, say in this small group of people these are the ages. 1,2,3,4,78,86,92. People wouldn't say the average age is 4 of that group, they would say the average is 38. 4 in this case is the median and 38 is the mean.
I completely overlooked the word "median" in the top. Thank you! =)
There were others too !
to the nearest year": A median age is always a whole number of years, since we don't normally measure people's ages in fractions of a year. So it isn't necessary to say "to the nearest year". It's only if you took the average age that you would need to round that number. For example, if you had to find the median age of three people aged 20, 25, and 50, then the median would be 25, without a need to round. Only if you had to find the average age, which is 31.666, would you need to round to the nearest year.
