A normal distribution has a mean of µ = 50 with σ = 10. What proportion of the scores in this distribution are greater than X = 65?
Scores on the SAT form a normal distribution with a mean of µ = 500 with σ = 100. What is the probability that a randomly selected college applicant will have a score greater than 640?
If a multiple choice test has five answers what is the probability of guessing the right answer?
You have a 50% chance of getting the right answer and a 50% of getting the wrong answer. You best bet is to eliminate your three worse/wrong answers and that leaves you with two that are more or less correct . I have taken tests where points are taken away for guessing. Each right answer was one point and for every wrong two points were taken off. This was a national standardized test. In all the testing I have taken I have no way to beat the system set up by testing. I have taken the LSAT, GRE, SAT, ACT, National Teachers Exam, and several others. Nothing beats getting the test prep book and learning the tricks for that particular test.
Which way do the x-axis and the y- axis go in horizontal bar graph?
On a bar graph you have the X-Axis and the Y-Axis, the Y-Axis is a vertical line (straight line facing up )and the X-Axis is the horizontal line (straight line facing down) if you want to remember where the Y-Axis is then you say north to south and you draw that and if you want to remember where the X-Axis is then you just sat east to west or you say, Yay Xmas (christmas)
What is a categorical variable in statistics?
WHAT THE HELL IS A CATEGORICAL VARIABLE! Actually hell may be an observation in a categorical variable what we might call "place of final rest". The term, categorical variable, can best be difined by examining it parts. The categorical part: a grouping of things with like characteristics, i.e., the going to hell group and the going to heaven group. Or how you group the women in a bar; the women with blonde hair, the women with red hair and the firey redheads. But notice there are different colors of hair; that is, hair color varies -- did I say varies? Yes I did. So when something varies or changes what do we have? A variable!! We can thing of hair color as a categorical variable. But notice also that we can think of sex as a categorical variable. But there can be only categories in the variable sex, male or female; unless your talking about the act of sex in which case, that is for me, there is only one category, infrequent. You might say that gender or sex can vary in only two ways, either you're male or you're female; there are no other choices. This means that the categorical variable has two degrees of freedom. How many degrees of freedom are in the categorical variable, sexual preference? So what do we have after all of this horseshit: things change; that is they vary. The number of blondes in a bar changes from night to night. Go to the bar and take a tablet with you. OK, you can scribble on a napkin if you want to...just don't get it soaked in beer. Write this prase at the top of the napkin: Number of blondes in the bar tonight." Beside that write the day, Monday, Tuesday, ect. Now sit and sip you draft and count the number of blondes on a Monday night and write that number down. 36 blondes on Monday night. Do the same for the other nights in the week. Here's the way your table might look: Day of Week Number of Blondes Mon 22 Tue 54 Wed 120 Thu 12 Fri 18 Sat 77 Sun 0 What can we say about the table. Well, we can say that we have counted the numberof blondes in the bar by day of the week. This is called tabulation or tallying. What are the categorical variales in the table? Notice anything unusual about Wednesday night?
Is possible to enter multiple addresses at once in a sat nav?
No, you will need to input the address more than once.
Can you select your best math score from one test with the best critical reading score from another test?
Yes. Your best scores on SAT sections can be combined to form your "superscore." Colleges will accept your "superscore" on the SAT. Colleges will not hold it against you if you take the SAT more than once.
How many attempts are there for the SAT exam?
There is no limit to the amount of times you can take the SAT exam. However, it is recommended to take it no more than three times. Any more and colleges may think you're not prepared.
Can i take the sat once I'm in college?
No. The SAT test is a test that colleges use to determine your qualification for their school, hence making it useless to take once you are already enrolled in a college.

Where to take an SAT in Kansas US in august of 2014?

What is the difference between SAT I and SAT II?
The SAT I is the reasoning test that most people take. It is out of 2400 and has Math, Critical Reading, and Writing sections. It is more of a measure of one's general academic and learning ability than a measure of mastery of a specific subject. The SAT II's are the SAT subject tests. These measure one's ability in very specific subjects such as languages, advanced math, and specific branches of sciences. The SAT II's are shorter more specialize (which can make them more difficult), and people typically only take them because they are going to an elite college or are opting out of classes.
Can my SAT score the one that universities consider be rounded down if I take it more than twice and get a worse score than before?
i think this is how it goes...in 2009, you can take the SAT test as many times as you want and in the end choose your best score and enter it the university. For 2008, i believe they accept the better score.
What is something not every student who wants to take the SAT must do?
Not every student taking the SAT needs to register for one or more SAT subject tests.
Do one really have to write SAT before they left high school?
No. There are colleges that do not require you to take the SAT to get in. Also a good alternative is the ACT, which is another standardized test which some people find easier to take than the SAT. But if you are looking to go to college, then the SAT is a good idea. If you are not going to college, then there is little to no reason to take it.
Does it look bad if you take the SAT or ACT multiple times?
After 28 years I am a returning student to the college arena. It does not reflect badly on you if you are required to take the SAT or ACT exams more than once. Much of the information and processes some of us had to learn has changed over time. So if getting updated knowledge and retaking these tests is needed I believe it is better to do so now than to give up the dream.AnswerNope. As long as you pass it, they do not care how much you take the tests. It just takes a lot of money out of your pocket. AnswerThey do not look at how many times you take the SAT/ACT tests. They just look at the highest score you got and that's it. Whether you take it 1 time or take it 5 times, the colleges don't care. Just your highest score. It only looks bad if your scores do not improve.AnswerSome colleges suggest that you should take the SAT at most three or so times. This is because taking five or six SAT's shows that you are overly desperate to get into that college (and there are better ways to show your desperation). My advice is to take it once and try to improve your score for the second exam.
