## Point By Point Agreement Ratio

If advisors tend to accept, the differences between the evaluators` observations will be close to zero. If one advisor is generally higher or lower than the other by a consistent amount, the distortion differs from zero. If advisors tend to disagree, but without a consistent model of one assessment above each other, the average will be close to zero. Confidence limits (generally 95%) It is possible to calculate for bias and for each of the limits of the agreement. Subsequent extensions of the approach included versions that could deal with “under-credits” and ordinal scales. [7] These extensions converge with the intra-class correlation family (ICC), which allows us to estimate reliability for each level of measurement, from the notion (kappa) to the ordinal (or ICC) at the interval (ICC or ordinal kappa) and the ratio (ICC). There are also variations that may consider the agreement by the evaluators on a number of points (for example.B. two people agree on the rates of depression for all points of the same semi-structured interview for a case?) as well as cases of raters x (for example. B how do two or more evaluators agree on whether 30 cases have a diagnosis of depression, yes/no a nominal variable).

There are a number of statistics that can be used to determine the reliability of interramas. Different statistics are adapted to different types of measurement. Some options are the common probability of an agreement, Cohens Kappa, Scott`s pi and the Fleiss`Kappa associated with it, inter-rate correlation, correlation coefficient, intra-class correlation and Krippendorff alpha. These combine with two operational definitions of behavior: Explanation: IOA for an event, when the frequency ratio is calculated as Bland and Altman[15], have expanded this idea by graphically showing the difference of each point, the average difference and the limits of vertical correspondence with the average of the two evaluations horizontally. The resulting Bland-Altman plot shows not only the general degree of compliance, but also whether the agreement is related to the underlying value of the article. For example, two advisors could closely match the estimate of the size of small objects, but could disagree on larger objects. Great post Tara. This is a great example of what many are trying to get with LER in the studio code.

Many of our clients in your example would have a slightly different approach.
