Evaluation
Definition
A statement of quality, goodness, merit, value, etc. about what has been assessed. (judgment)

reference

What are the six general purposes of measurement and evaluation?
Definition
placement, diagnosis, prediction, motivation, achivement, and program evaluation
Term
Placement
Definition
An initial test and evaluation that allows a professional to group students into instruction or training groups according to their abilities. (to assign membership to the most appropriate level of performance - also called selection or classification)
Term
Diagnosis
Definition
Evaluation of test results is often used to determine weaknesses or deficiencies in subjects. (to identify the remediate weaknesses in performance)

Achievement
Definition
The measurement and evaluation process is necessary for motivating your students and program participants. (to encourage people to improve on performance)
Term
Program Evaluation

Psychomotor domain
Definition
This domain includes reflexive movements, basic locomotor movements, perceptual motor abilities, physical abilities, skilled movements, and nondiscursive movements.
Term
Whats the difference between an ability and a skill?
Definition
Ability is something that is more or less inate, a skill is learned.
Term

Definition
The awareness you have of your body in space. No concrete way to measure this.
Term
Physical activity
Definition
bodily movement that is produced by the contraction of skeletal muscleand that substantially increases energy expenditure
Term
Descriptive statistics
Definition
these provide you with mathematical summaries of performance and performance characteristics (the best score or the variability)
Term
One method of classifying numbers if using scales of measurement, such as ______
Definition
Nominal, ordinal, and continuous
Term
Nominal
Definition
Naming or classifying. This is categorical in nature, without order or magnitude.
Term
Ordinal
Definition
A ranking, such as finishing place in a race.
Term
Interval
Definition
A unit of measurement that does not have an absolute zero
Term
Ratio
Definition
Same as interval, except having an absolute (true) zero, such as weight or distance
Term
Only ___ and ____ numbers can be subjected to mathematical operation
Definition
Ratio; interval
Term
Mathematicians have developed a shorthand system called ____
Definition
summation notation
Term
A positively skewed distribution has a "tail" toward the _____ end of the number line.
Definition
positive
Term
Kurtosis
Definition
This describes the peakedness of a curve.
Term
In relation to peakedness, curves can be either
Definition
mesokurtic, platykurtic, leptokurtic
Term
A good way to determine the shape of the distribution you are working with is to develop a ____
Definition
histogram
Term
Range
Definition
The range is the high score minus the lower score
Term
Variance
Definition
Variance (s^2) is a measure of the spread of a set of scores based on the squared deviation of each score from the mean
Term
What is the formula used to illustrate variance?
Definition
(page 41)
Term
Observed score variance
Definition
Not everyone scored the same
Term
True score variance
Definition
Not everyone has the same "true" knowledge about the content of the test
Term
Error score variance
Definition
There is some "error" in the test, but not everyone has the same amount of error reflected in their scores.
Term
