Reliability is about a method's consistency, and validity is about its accuracy. You can assess both using various types of evidence.

Two important qualities of surveys, as with all measurement instruments, are consistency and accuracy. These are Feb 21, 2011 Validity is about measurement accuracy. Reliability is about internal consistency. To achieve both, good survey design is a must.

Overview. In this Exploring Reliability and Validity Assignment, you will analyze the psychometrics provided from the Values and Motives Questionnaire (VMQ), addressing 1) the type of reliability and validity used; 2) the areas of concern/strength for the Cronbach alpha coefficients; 3) how sample size and nature of the population may influence the constructs that the test attempts to measure

Reliability and Validity in Research – This is a statistical concept in the field of research whereby a particular phenomenon is being evaluated or rated by various raters. It is, therefore, the extent or degree to which there is an agreement in the rating scores amongst the multiple raters, which brings about homogeneity and unanimity

From either perspective, the instruments that are used in a study must be evaluated. Researchers often face the challenge of developing new instruments and, as part of that process, establishing the reliability and validity of those instruments.

For example, a reliable reading test which consists of gap filling questions on grammatical items cannot be regarded valid for assessing reading comprehension.

High reliability is one indicator that a measurement is valid. Reliability and Validity: Ensuring Reliability 1. Consistently Apply the Methods Carefully plan your methods to ensure you get to follow the same set of steps for 2. Standardize the Research Conditions Validity shows how a specific test is suitable for a particular situation. If the results are accurate according to the researcher's situation, explanation, and prediction, then the research is valid. If the method of measuring is accurate, then it’ll produce accurate results.

It’s important to consider validity and reliability of the data collection tools (instruments) when either conducting or critiquing research.
