One reason we need standardized tests is because in American high schools nearly everyone gets top marks - The average GPA for an American high school student is about a 3.4. And many schools have stopped ranking because they don't want to hurt the kids feelings or deal with the hassles that come from overbearing parents who don't like Junior's grades and are ready to complain anytime their little genius gets less than an A.  \n\nSo, how are the colleges supposed to tell whether a kid actually learned anything in high school. If there are 10,000 applicants for 1000 positions, how do you decide? No college decides on SATs alone, but if you have a kid who supposedly got all As and Bs and who then shows up with mediocre SAT scores, then that is a bad sign. And another sign is a kid who supposedly took AP courses, but never took any AP tests.\n\nAt some point you have to be able to say, this kid actually knows something, and can prove it on a straightforward set of questions about basic things that he should know. Getting mediocre SAT scores, and then graduating from a mediocre college with mediocre grades is very predictable. In general, people who are able to handle the immense workload at the top colleges had pretty high SATs... check the websites at the Ivies, Duke, Stanford, Chicago for the levels these smart, hardworking kids made in their SATs.

I concur. Also with the ACT, but I'm starting to believe more in it now since I got a very high score, higher than what my grades would put me as, showing I am unmotivated :D I got suckered into an AP exam and I guess it's okay if you want to pay 80$ and die slowly yet surely when the questions keep coming and coming... I liked the SAT, though, because it was based more on grammar and literature, though I don't know a use for it.

Buy your self a Kaplan AP Calc. book. Our teacher recomended it. It helps you to go over all the things that you have leant in past year. I personally had bought Spark Notes one. Because it had flashcards in it. Those books helps you a lot if you have less time to prepare.\n\nP.S. if your school has AP Stat teacher or High school calc. teacher go ask them for some help. I am sure they won't deny. BEST LUCK for the exams.

Broad question! Focusing it would help us answer better.\n\nReally basic stats would do things like tally and sum, average, find the median of the subjects you are testing.\n\nOnce you have those descriptive statistics, you can do things like compare outcomes between groups. Suppose you have two samples of people. One group has a mean life expectancy X. The other has mean life expectancy Y. To determine whether X and Y are significantly different from each other, you could do a Student t-test to determine whether the difference in values of X and Y are truly significant, or differ only by chance.\n\nthat's just one example. there are tons more!

Well, as a teacher of AP US history classes, you learn all about US history, which seems a bit obvious.  Almost all students who take the class (at least where I teach) plan on taking the AP exam in May.  Therefore, there's a strong focus on factual content and we cover the entire subject, from discovery and settlement to modern times.  Students have about 8-15 pages of reading a night, homework questions, an electronic bulletin board, papers, biweekly quizzes, and tests, which include multiple choice, short answer, and essays.  There is also practice for the DBQ - document based question - which asks you to take a position and defend it, using the documents you are given as well as your outside knowledge on the topic.  \n\nIn essence, while you learn content, you also learn discipline, how to write, how to think analytically, and how to construct a historical argument.  While the work is challenging, I don't think it's impossible.\n\nIf you are asking because you are thinking of taking the class next year, I hope you do take it.  It's a lot of work but very much worth it!  Good luck.

"z-test" usually refers to normal distribution. Which means \n1) That the population is normal \n2) That the population parameters (mean and variance) are known\nthen you can test against a Z by letting z=(x-mu)/sgima, that distributes normal-standard.\n\nNow, if you don't know the population parameters, then you go the t way (Correctly known as STudent-t to honor its inventor)\n\nNow, t aproaches z as sample size grows. In practical terms, it means that ,for sample sizes below 100 you use t and for larger samples you use normal

Yes and no, yes in the fact that if he can handle the course work he will be ahead of the curve when it comes time to go to college (meaning he'll be on track to take AP-calc), and if he can do well on the AP test then he will have a better chance, over someone with the exact same application less the AP test score.\nThe no being that it works up the assumtion of getting a 3-5 on the AP test, and he does well in the advanced track

I live in South Carolina, and have a son in the public education system. I have an ex sister-in-law who taught AP history. What precisely would you like to know?

You must  write your question more understandable.\n\nFor the test results, you can calculate the average, variance, standard deviation, min and max grades. You can also find the frequency of the marks.

You can expect mind numblingly boring calculations for most of your summer.  The mathematics behind statistics is fairly elementary, it's the staying awake and alert part that's difficult...\nGood Luck, I had to take Statistics in college, and I have to say... It was the best one hour nap 3 times a week a person could possibly ask for...

An exam that tests the knowledge of those who have taken the AP Calculus course in their high school. It's usually given at the school around final exam time (at least mine were) and if you pass the exam (3,4, or 5), you are likely to receive credit for the equivalent course in college. This website is also very informative: http://www.collegeboard.com/student/testing/ap/about.html.

In general, what statistics does is it tells us what is going on by giving us measurements. These measurements can then be used to evaluate things.\n\nMedicine: We use statistics to determine how effective treatments are and whether or not they are safe. Say we have a new cancer drug and want to know if it is both safe and effective. We may test it out by undergoing an experimental procedure. We give one set of randomly chosen patients a "placebo" (a fake drug) and another the real one. After a certain amount of time, we try to see if there is a difference between the two groups. Before any drug gets to the human testing stage, it must first be evaluated on non-human subjects, such as in laboratories and on lab animals. \nEducation: We may want to know how many students are passing and failing, or how effective a teaching system is. Say you want to improve test scores and you have a new teaching system. You administer this to a group of random students- much like with a new drug- and try to determine if there are any differences between the treatment ("testing") group and the control (non-testing) group. If you cannot conduct an experiment, you simply try to observe a lot of students and try to see if the ones who are doing better also happen to be using the new teaching system.\n\n\nThe basic procedures of testing are the same throughout each of the fields. You can either conduct actual experiments, where you determine who is in your testing and control groups, or you can simply observe a large number of subjects and try to notice patterns or differences. Here are some other examples.\n\nMilitary: test the effectiveness of a new weapons system. \nPsychology: Statistics grew out of te desire by psychologists to measure things like intelligence and human behavior. Today, many psychologists are branching into biology, where they are testing hormone activity in the brain.\nSociology: We may want to determine the connection between handgun laws and violence.\n\nAt all these levels we try to understand the world by breaking it down into smaller components. We then try to find the patterns (statisticians call these "correlations"). For example, we might determine that a new brand of fertilizer is correlated with larger crops (agriculture). \n\nBusiness-people are concerned with statistics that reveal how wella product or service is selling. Imagine that you are a huge corporation that sells pop soda, and you have a new TV advertisement that markets the soda. Is the advertisement effective? You may want to gather statistics about how consumers view the advertisement (either through directly asking them- such as through a poll or a panel where people sit down and answer questions face-to-face) or by observing the change in sales.  If your sales grow drammatically right after you introduce the new ad, there is good reason to believe that part of that has to do with the ad itself.\n\nKeep in mind that researchers always try to not immediately assume that correlation means causation. That is, just because two things tend to go together does not mean that either one causes the other. The only ways we can make sure that one thing does cause the other (for example, a good drug may "cause" a person to become healthier) is to rule out other possibilities. When we gather a lot of data ("statistics") about something, it helps us eliminate alternative possibilities. For example, when we administer a new drug to a treatment group, we want to make sure that they are not already taking a medication that may interfere with the outcome. Without doing this, we might think that the effectiveness of our drug comes entirely from it. In a sense, the "control" helps us remove some of that uncertainty, because it keeps everything but the treatment the same.

In some sense, no test reflects what a person REALLY knows.  All tests pick some set of questions to "sample" what a person knows, and then extrapolate from there.  (There is virtually no test which goes methodically through every piece of knowledge to see exactly what a person knows or doesn't know.)\n\nBeyond this, there's always the chance that, due to psychological factors or due to the physical design of the test, a student will give a wrong answer even though she or he knows the right answer.\n\nBut the limitations described above apply to all tests.  Standardized tests are typically designed carefully to minimize sources of error.  \n\nOne of the things that standardized tests have in their favor is that they don't attempt to try to measure "raw" knowledge.  Rather, they ask the same questions of a group of people and then give a ranking within that group.  Who knows the most (scores the highest)?  Who knows the least (scores the lowest)?\n\nBecause the standardized tests give ranked scores, then, they're not designed to reflect "what students really know."\n\nI guess this means that the basic answer to your question is that standardized tests do "reflect" what students really know, but that they are not designed to give a direct measure of what students really know.
