The Kuder and Richardson Formula 20 test 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.
88 The data of the split-half were used and ˆ3 and ˆ˚ were computed. They were as under ˆ3 ˛ = 135.53 ˆ˚ ˛ = 2049.59 These value were inserted in the above mentioned formula and ˚˚ was computed as under.
This is an adaptive test. The questions in each section start easy and get harder. Younger children will not usually finish all questions in each section, but age (entered later) is factored into the scoring formula and IQ is calculated in relation to children the same age.

Cronbach's alpha will generally increase as the intercorrelations among test items increase, and is thus known as an internal consistency estimate of reliability of test scores. Because intercorrelations among test items are maximized when all items measure the same construct, Cronbach's alpha is widely believed to indirectly indicate the degree to which a set of items measures a single ...
Reliability does not imply validity.That is, a reliable measure that is measuring something consistently is not necessarily measuring what you want to be measured.
Grado en que un instrumento produce resultados consistentes y coherentes. Es decir en que su aplicación repetida al mismo sujeto u objeto produce resultados iguales.

ABSTRACT. Considering the relevance of obtaining trustful measurement for the evaluation of intelligence, this study aimed at verifying the convergent validity between the R1-Forma B and the G36 tests. 78 students of both gender (34,6% female and 65,4% male), aged from 15 to 64 years old (mean = 36,84; SD = 10,10) and attending to the high school Telecurso were studied.
The purpose of the study was to investigate whether Exemplary, Recognized and Acceptable schools differ in their school climates, as measured by the 10 dimensions of the Organizational Health Inventory. Significant differences were found on all 10 dimensions of the Organizational Health Inventory, with Exemplary schools out‐performing Acceptable schools.
