Perhaps there needs to be some clarification. Private schools do above average on SATs. Homeschoolers do above average on SATs. Guess who that average is? Hint: everyone can't be above average. Public high schools as a whole cannot BY DEFINITION be above the median. They are the median.
"The median is the middle of a distribution:
half the scores are above the median and
half are below the median."
"100, 100, 99, 98, 92, 91, 91, 90, 88, 87, 87, 85, 85, 85, 80, 79, 76, 72, 67, 66, 45 The middle score of this group is 87. Exactly half of the scores lie above
87 and half lie below it. Thus, 87 is in the middle of this set of scores.
This score is known as the
median."
This is
BY DEFINITION. So according to your statement "public schools
are the median"?? So public schools would represent the median and homeschoolers are above the 87? Who is below?? BY DEFINITION
half the scores fall above the median and half below. There are not enough homeschooler to make up 1/2 of all SAT scores! See my point??? So most of the kids above the median
are public schoolers.
They do not mean ALL home schooler are above the 87 (I am using this as an example and an quite aware that this is not how The SAT is scored) So you do not think that out of a chunk of America's public school students, we could find a group that scored higher than homeschoolers? I do, since there are
so many more public schoolers. There are some HUGE (1,500 per grade) public schools here in Dallas, especially in the affluent suburbs that the students score exceptionally high. I do agree that America's innrer city public schools, typically do not score well but that does not mean that homeschoolers score higher than public schoolers, you cannot make statements like that since there are so many more public schoolers-it only means they score above the middle line.
