This is the general form of the more commonly reported KR and can be applied to tests composed of items with different numbers of points given for different response alternatives. When coefficient alpha is applied to tests in which each item has only one correct answer and all correct answers are worth the same number of points, the resulting coefficient is identical to KR Further discussion of test reliability can be found in J.
Standard Error of Measurement The standard error of measurement is directly related to the reliability of the test.
Whereas the reliability of a test always varies between 0. For example, multiplying all test scores by a constant will multiply the standard error of measurement by that same constant, but will leave the reliability coefficient unchanged.
A general rule of thumb to predict the amount of change which can be expected in individual test scores is to multiply the standard error of measurement by 1. The smaller the standard error of measurement, the more accurate the measurement provided by the test. Further discussion of the standard error of measurement can be found in J.
Such statistics must always be interpreted in the context of the type of test given and the individuals being tested.
Lehmann provide the following set of cautions in using item analysis results Measurement and Evaluation in Education and Psychology. Holt, Rinehart and Winston, Item analysis data are not synonymous with item validity.
An external criterion is required to accurately judge the validity of test items. By using the internal criterion of total test score, item analyses reflect internal consistency of items rather than validity.
The discrimination index is not always a measure of item quality. There is a variety of reasons an item may have low discriminating power: Item analysis data are tentative.
Such data are influenced by the type and number of students being tested, instructional procedures employed, and chance errors. If repeated use of items is possible, statistics should be recorded for each administration of each item. Furthermore, separate analyses must be requested for different versions of the same exam.
Return to the text. In negative relationships, the value of one variable tends to be high when the other is low, and vice versa. The possible values of correlation coefficients range from The strength of the relationship is shown by the absolute value of the coefficient that is, how large the number is whether it is positive or negative.
The sign indicates the direction of the relationship whether positive or negative.First of all this book has only writing topics so I don't know why it is titled writing topics. I guess it isn't a math book. Having just begun to examine the book I discover it is published in Korea and clearly is authored by someone who speaks English as a second language.
