when it seems no matter how much you explain something, the person you are explaining to just don't get it.

I just spent two hours trying to explain what mean, median, and mode are when it comes to a group of numbers. Explained in really simple terms... mean is when you add everything up and then divide by how many numbers you added up (in other words, it means AVERAGE, ya know, that math formula learned in like the 3rd or 4th grade?). Mode... count how many times a value appears in the list and what ever value shows up the most is the mode (ya know, the MOST FREQUENT). Median, put 'em order, count to you hit the middle and that would be the median (this may explain why it sounds like MIDDLE).

Gave this person 9, count 'em ... NINE numbers, easy numbers.... 2,2,2,9,7,6,5,4,3... simple numbers. Didn't even attempt to double digit ones here.

Not ten minutes later.... "I don't know what to do!!!!"

Gonna go find another wall to since I just wasted 2 hrs of my life I coulda spent reading BYC.

OH... forgot to mention, the person in question is a 37 y/o mother of two in her SENIOR year of college pursuing a degree in criminal justice.

Quote:I dunno. I am bad at math... And I had a hard time understanding what you said...
Mean- 40 (the numbers all added up) divided by 9 (the number or numbers) which equals 4.44 (that would the mean) I hate to say it... it doesn't sound right even if it is...
The average of the numbers is when you divide the number of numbers you added up.. that kinda makes more sense.. If you had explained that a person adds up 7, or 10 or 21 numbers.. then divides by that number NOT the end product.. that is the addition.. if you count the numbers in the sequence and divide that number to the end product of the addition.. that gives you the average or mean.
And it is basic algebra, Not a lot of people do algebra, and algebra is not 3rd or 4th grade.
