50 question test. 800 is the highest an all i need is a 410.. how many can i get wrong?

Answer 1

The "800" and "410" scores you are referring to are standardized scores in which 500 is the average or at the 50th percentile; thus 600 and 700 are at about the 86th and 98th percentile respectively while 410 is at about the 18th percentile.  There is no way to calculate what  number of correct answers you need to meet a given standardized score without knowing the standardization data.  These data are based on the total number of students who took the test which may be in the thousands.

Answer 2

800 points / 50 questions = 16 points/question.

410/16 = 25.625 questions must be answered correctly.

So for a 410, you need a minimum of 26 correct, and 24 wrong.

I hope you weren't talking about the SAT, otherwise the answer is completely different.

Answer 3

Each question is worth 16 points.

So 410 points/16 points comes up to:

25 questions allowed wrong.

Answer 4

Be careful.  It depends on what the type of test you have.  A criterian referenced test is based on how many questions you get right.  In this case, each question is worth 16 points.

However, many tests are norm-based.  And in that case, you're not scored against the test...you're scored against what the "normal" student would make.  Students scoring in the 50th percentile, for example, would be perfectly "normal" and scoring in the 95th percentile would mean that you scored better than 95% of the norm population.

So, in that case, there's no way to know how many questions it takes to reach a norm of 410.

Answer 5

24 when you take in account the fraction to be safe.

800 / 50 = 16

410/16= 25.625 or 26 right

50-26= 24 wrong

For a basic test only.

Answer 6

as explained above
