Question 1

Standardized Test

Answer 1

A test designed to gather either norm-referenced or criterion- referenced guesses and is given, scored, and translated in a standard, decided prior to the test. Standardized testing are created and sold by testing firms.

Question 2

Norm- Referenced

Answer 2

Focuses on students aptitude and achievement, including teachers achievement and are required to satisfy a state legislative mandate on what standards they are to preform on.

Question 3

Criterion- Referenced

Answer 3

Focuses on educational aptitude, utilizing selected and constructive responses because the state legislative mandates a certain number of those questions to assess the standards.

Question 4

Mean

Answer 4

the average score out of all the students in the testing group, using the raw scores and an athematic equation of adding all the scores and dividing the total by the number of students.

Question 5

Median

Answer 5

the middle point of the test group, utilizing the raw scores.

Question 6

Standard Deviation

Answer 6

is the average difference of the scores of individual students in the group and the mean of the set of scores. The bigger the deviation the larger the “distribution” is spread out.
SD= (Square Root of) (E(x-M)^2)/ N

Question 7

Percentiles

Answer 7

shows the difference in the students score compared to others in a “Norm” group. stating how many students that one student based on his score, outperformed. the student compared to the group

Question 8

Grade- Equivalent Scores

Answer 8

utilizes the grade level and months of the school year the students performance indicated. This is used to show the students performance and growth student should show throughout the year. its a continuous range of grades based on a progression of performance. Ex. 6.2 is sixth grade and 2 months into the year.

Question 9

Scaled Score

Answer 9

A statistical score used to compare among the state, district and school level, it is often used by the schools and teachers to comparisons at those three different levels. Higher the number higher the scale score. a converted numerical scale of raw scores to statistical scores.

Question 10

Item response theory

Answer 10

a type of scaled score reporting system, taking into account the difficulty and items on the assessments.

Question 11

Normal Curve Equivalent

Answer 11

Utilizing a scale score to determine performance, but hypothetically assuming the scores from the test are perfectly bell shaped giving an accurate interpretation of the score.

Question 12

Stanine

Answer 12

uses the assumption of normal distributions among the scores, its a scale score with this assumption in mind to graph along an equally pieced curve to show student an approximate score depending on the normal curve.

Question 13

P-Value

Answer 13

used for the item difficulty index, with a formula of p=R/T. is should be noted that its a probability relationship of the student getting the answer correct by guessing.

Question 14

Item- Discrimination index

Answer 14

shows a relationship between the students answers on the test and a specific item on the test, and whether or not the students can get them correct.

Question 15

Standard Error of Measurment

Answer 15

an index to scale a persons performance on a particular assessment. its shown as a consistency index if a student was assessed over and over again with the same instruction.
