The COVID-19 Pandemic drastically changing all aspects of our world, and one of the most impacted areas is educational assessment and other types of assessment.
This collusion detection (test cheating) index simply calculates the number of responses in common between a given pair of examinees. For example, both answered ‘B’
Exact Errors in Common (EEIC) is an extremely basic collusion detection index simply calculates the number of responses in common between a given pair of
This exam cheating index (collusion detection) simply calculates the number of errors in common between a given pair of examinees. For example, two examinees got
Harpp, Hogan, and Jennings (1996) revised their Response Similarity Index somewhat from Harpp and Hogan (1993). This produced a new equation for a statistic to
Harpp and Hogan (1993) suggested a response similarity index defined as where EEIC denote the number of exact errors in common or identically wrong,
This index evaluates error similarity analysis (ESA), namely estimating the probability that a given pair of examinees would have the same exact errors in common
The Frary, Tideman, and Watts (1977) g2 index is a collusion (cheating) detection index, which is a standardization that evaluates a number of common responses
Wollack (1997) adapted the standardized collusion index of Frary, Tidemann, and Watts (1977) g2 to item response theory (IRT) and produced the Wollack Omega (ω)
Wesolowsky’s (2000) index is a collusion detection index, designed to look for exam cheating by finding similar response vectors amongst examinees. It is in the
Wise and Kong (2005) defined an index to flag examinees not putting forth minimal effort, based on their response time. It is called the response
The Holland K index and variants are probability-based indices for psychometric forensics, like the Bellezza & Bellezza indices, but make use of conditional information in
FastTest has been ASC’s flagship platform for the past 11 years, securely delivering millions of online exams powered with computerized adaptive testing and item response
A psychometrician is someone who practices psychometrics – the Science of Assessment. That is, they study the process of assessment development and validation itself, regardless
