4 The formula is sum of scores divided by number of scores.
Standard deviation is the square root of the mean. The mean for this set is (2 + 4 + 3 + 7)/4 = 16/4 = 4; the square root of this is 2.
A negative correlation is when you compare 2 sets of data on a line graph (e.g. scores in a French test and scores in an English test), the higher one thing is, the lower the other is (e.g. someone might score 98% on the French test but only 12% on the English test (or visa versa)). A positive correlation is the other way around. A weak correlation is when there is a lot of deviation from the line of best fit (there will always be one with correlations as a line of best fit shows correlations after all) whereas with a strong correlation, there is little deviation.
the arithmetic mean for the set of numbers is 7.4. but the geometric mean is 6.25826929.
The median of a set of data is used for similar purposes as the mean. They both give you a middle number that represents what the set of data fluctuates around. While the mean gives you the exact center, the median simply gives you the middle piece of data. The following is an example of why the median is sometimes more helpful than the mean: Consider a class of 5 students that take a test that is scored on a scale of 0 to 500. The scores of the students are as follows: 1) 25 2) 120 3) 102 4) 248 5) 500 The mean of the scores is (25+120+102+248+500)/5 = 199 The median of the scores is 120 Looking only at the mean, the teacher may get the impression that the students are more skilled than they really are, since the average score of the class is 40% of the highest possible score. However, one student scored only 49 points higher than the mean and the other 3 didn't get within 70 points of it. Looking at the median, the teacher sees that another accurate representation of the scores is 120. This is only 24% of the highest possible grade and better represents what most of the class got. Unlike the mean, the median wasn't set deceivingly high by the one student with a perfect score.
The mean absolute deviation is 5
68% of the scores are within 1 standard deviation of the mean -80, 120 95% of the scores are within 2 standard deviations of the mean -60, 140 99.7% of the scores are within 3 standard deviations of the mean -40, 180
2, 2, 5, 7, 9, 11. Mean = Median = 6 Mode = 2
If scores of zero are permitted, the lowest median is 2 as in (0,1,2,3,44) and the highest median is 10 as in (8,9,10,11,12). If a zero score is not permitted, then the lowest median is 3 as in (1,2,3,4,40).
Note: The following information is from the UCLA.edu website (link below).Test RequirementsStudents must submit scores on an approved core test of mathematics, language arts, and writing. This requirement can be satisfied by taking the following:* The ACT Assessment plus the ACT Writing Test. Both tests must be taken at the same time; we do not combine test scores from multiple sittings.- or -The SAT Reasoning Test with critical reading, mathematics, and writing scores from the same sitting.- and -* Two SAT Subject Tests in two different subject areas*:o English (literature)o history/social studieso mathematics (Level 2 only)o scienceo languages (other than English)* Applicants to the Henry Samueli School of Engineering and Applied Science are strongly encouraged to take the following SAT Subject Tests: Math Level 2 and a science test (Biology E/M, Chemistry, or Physics) that is closely related to the applicant's intended major.Take these tests as early as possible, and have your test scores sent directly to UCLA. December of your senior year is the latest you can take any test in time for scores to be used for our selection process.
You add the scores together and then divide by the number of scores. So if you rolled a dice and your scores were, 3, 5, 2, and 6 You would add these together, getting 16, and then you would divide this by 4 (because you have 4 scores) and so your mean would be 4 (16/4=4) sum of scores / number of scores = mean. Hope this helps.
T-scores have a mean of 50 and a standard deviation of 10. These values are fixed and do not change regardless of the distribution of T-scores.
Scores will vary according to the specific school. Applicants must submit test scores from the Graduate Record Examination (GRE), the Veterinary College Admission Test (VCAT), or the Medical College Admission Test (MCAT), depending on the preference of the college to which you are applying. Currently, 22 schools require the GRE, 4 require the VCAT, and 2 accept the MCAT. However, admissions to veterinary school is very competitive. The school will be looking at you as an entire individual, and not just in parts. In other words, the admission decision is not based solely on test scores, but may also include the following. Admission factors: * Class Rank * Rigor of undergraduate coursework and prerequisites * Standardized Test Scores * Academic GPA Considered: * Application Essay * Extracurricular Activities * Geographical Residence * Racial/Ethnic Status * Recommendations * State Residency * Volunteer Work * Work Experience
Test Scores for 2006-2007 SAT verbal scores over 500 70%, SAT math scores over 500 66%, ACT scores over 18 94%, SAT verbal scores over 600 25%, SAT math scores over 600 21%, ACT scores over 24 33%, SAT verbal scores over 700 4%, SAT math scores over 700 3%, ACT scores over 30 2%
z=-20/12 = -1.667 Assuming normal distribution, P(Z < -1.667) = 0.04779 or 4.8% of the scores should be less than 50. You can get the probabilities by looking them up on a table or use Excel, where +Normdist(50,70,12,true). My normal table has only 2 digit accuracy so for -1.67 = 0.0475.

Ah, where are the good old days, when a score of 72 was always better than a score of 62, and that was all you needed to know, and it didn't matter how well or poorly anybody else in the class was doing ? Sam Levinson used to tell about the time his son brought home a report card, and on the report card the teacher had written "For him, he is doing good", and Sam used to say, "Now all I need to know is: Who is 'him' ?"
The Token Test for Children - Second Edition (TTFC 2) is a standardized test used to assess children's language and auditory comprehension skills. It typically involves tasks where children listen to instructions and then demonstrate their understanding by performing specific actions with tokens or objects. Results from this test can help identify language impairments and guide intervention planning.
