What is Kuder Richardson formula used for?
In psychometrics, the Kuder–Richardson formulas, first published in 1937, are a measure of internal consistency reliability for measures with dichotomous choices.
What is KR-20 in testing?
Kuder-Richardson Formula 20, or KR-20, is a measure reliability for a test with binary variables (i.e. answers that are right or wrong). Reliability refers to how consistent the results from the test are, or how well the test is actually measuring what you want it to measure.
Which method of reliability Below is the Kuder Richardson formula 20 is applicable?
Kuder-Richardson Formula 20, or KR-20, is a measure reliability for a test with binary variables (i.e. answers that are right or wrong).
How do you read Kuder Richardson?
Kuder Richardson 20 This statistic measures test reliability of inter-item consistency. A higher value indicates a strong relationship between items on the test. A lower value indicates a weaker relationship between test items. Values range from 0 to 1.
What is KR 20 in testing?
What is the Kuder and Richardson Formula 20test?
The Kuder and Richardson Formula 20test checks the internal consistency of measurements with dichotomous choices. It is equivalent to performing the split-half methodology on all combinations of questions and is applicable when each question is either right or wrong. A correct question scores 1 and an incorrect question scores 0.

What does ST2 mean in Kuder-Richardson Formula?
where si2 is the variance of scores on item i, and st2 is the variance of the total test scores. Although the Kuder-Richardson formulas are applicable only when test items are scored “0” (wrong) or “1” (right),
What is the KR20 coefficient of Kuder in R1?
KUDER(R1) = KR20 coefficient for the data in range R1. Observation: For Example 1, KUDER(B4:L15) = .738.
