in the process of measurement, reliability refers to

For example, if a person weighs themselves during the course of a day they would expect to see a similar reading. a. A personality test should produce the same results every time for the same participant. Test reliability Reliability refers to how dependably or consistently a test measures a characteristic. Reliability refers to how consistent the results of a study are or the consistent results of a measuring test. Reliability refers to whether or not you get the same answer by using an instrument to measure something more than once. Reliability as stability is defined as the ability of a measure to remain the same across time (Mohajan, 2017). For example, if the test is increased from 5 to 10 items, m is 10 / 5 = 2. Test-retest reliability is a measure of reliability obtained by administering the same test twice over a period of time to a group of individuals. In the process of measurement, reliability refers to _____ asked Sep 8, 2016 in Sociology by Douglas. For example, let’s say you take a cognitive ability test and receive 65 th percentile on the test. For example, if a test is designed to measure a trait (such as introversion), then each time the test is administered to a subject, the results should be approximately the same. validity: Term. whether or not everyone agrees with the study's results. Usually, this is assessed in a pilot study, and can be done in two ways, depending on the level of measurement of the construct. For example, if a weight measuring scale is wrong by 4kg (it deducts 4 kg of the actual weight), it can be specified as reliable, because the scale displays the same weight every time we measure a specific item. Which of the concepts listed below refers to measuring exactly what one intends to measure? Content reliability b. Reliability alone is not enough, measures need to be reliable, as well as, valid. Scales which measured weight differently each time would be of little use. Instrument is the generic term that researchers use for a measurement device (survey, test, questionnaire, etc.). In a clinical trial, the measurement reliability plays a very important role, since it affects the choice of the primary outcome and the choice of eligibility and exclusion criteria. Reliability refers to a condition where a measurement process yields consistent scores (given an unchanged measured phenomenon) over repeat measurements. introductory-sociology; 0 Answers. Identify the following term that most closely refers to a judgement of the extent to which scores from a test can be used to infer, or predict, the examinees' performance in some activity: a. In simple terms, research reliability is the degree to which research method produces stable and consistent results. With respect to psychometrics, it is known as test validity and can be described as the degree to which the evidence supports a given theory. Definition. These two attributes are related to the accuracy and precious measurement in a study. Equivalent forms reliability b. Split-half reliability c. Test-retest reliability d. Inter-scorer reliability 19. It refers to the extent of applicability of the concept to the real world instead of a experimental setup. b. how dependable the researcher is. Reliability, on the other hand, is concerned with the consistency, accuracy, and predictability of the research findings. how dependable the researcher is. RELIABILITY Reliability refers to the consistency of measurement Reliable test from MECHANICAL 108 at University of California, Berkeley whether repeating the measurement yields consistent results. Jul 25 2018 06:51 AM . (Does it measure what it is suppose to measure) Reliability- Produces stable, consistent measurements. Test-Retest Reliability. Perhaps the two most common technical concepts in measurement are reliability and validity. Reliability; Meaning: Validity implies the extent to which the research instrument measures, what it is intended to measure. Exhaustive and mutually exclusive attributes. Reliability in qualitative studies is mostly a matter of “being thorough, careful and honest in carrying out the research” (Robson, 2002: 176). Like external validity, construct validity is related to generalizing. answered Sep 8, … Previous question Next question Get more help from Chegg. In quantitative research, you have to consider the reliability and validity of your methods and measurements.. Validity tells you how accurately a method measures something. Reliability refers to the degree to which assessment tool produces consistent results, when repeated measurements are made. In this sense, the involvement of the researchers in the research process would greatly reduce the validity of a test. • Reliability of a measure refers to the extent to which the measurement process is free from random errors. Term . The process of a measure, a tool, or an instrument's quality assessment involves investigating their reliability and validity. Validity implies the extent to which the research instrument measures, what it is intended to measure. Because the measurements were all made by one observer, the reliability may be referred to as intraobserver reliability. whether or not everyone agrees with the study's results. Reliability is directly related to the validity of the measure. There are several important principles. Instrument: A valid instrument is always reliable.
