The validity of the instrument used for measuring misconception about TB should be discussed. By validity here is meant the degree to which a measurement measures the true value of the variable. Surely, the validity is not 100% for a measurement as subjective as the question on modes of spread of TB. Given this, some of the variation in the rates of misconception may be explained by differences...

Abstract Introduction Accurate measurement of sleep is a challenge for researchers and practitioners. Objective measures (i.e., polysomnography, actigraphy) are expensive time-consuming. Thus, the practical approach self-report – with cost reduced validity. The purpose this actigraphy ­experiment was to compare validity differently ­formatted self-reported duration measures. It hypothesized tha...

Developing students' positive attitudes toward a situation is extremely important. Many attitude scales aim to measure general situation, but there scarcity of tools that can be easily employed determine the type questions students prefer in an exam. This paper reports development and testing instrument like this for secondary school students, 781 participated study. The Exam Question Types Att...

This article examines the reliability and validity of the modified essay question. An 18-item modified essay question was developed and pretested on a group of clinical experts. After the pretest, the modified essay question was administered to a group of 25 physical therapy students immediately before their second level orthopedic placement. A reliability index of .39 (coefficient alpha) was c...

Three studies were conducted to examine the validity of the four versions of BIATs that are supposed to measure the same construct but differ in shared focal category. Study 1 investigated the criterion validity of four BIATs measuring attitudes toward flower versus insect. Study 2 examined the experimental sensitivity of four BIATs by considering attitudes toward induced ingroup versus outgrou...

Cognitive Science research is hard to conduct, because researchers must take phenomena from the world and turn them into laboratory tasks for which a reasonable level of experimental control can be achieved. Consequently, research necessarily makes tradeoffs between internal validity (experimental control) and external validity (the degree to which a task represents behavior outside of the lab)...
