The median polish is a simple and robust exploratory data analysis procedure proposed by the statistician John Tukey. The purpose of median polish is to find an additively-fit model for data in a two-way layout table (usually, results from a factorial experiment ) of the form row effect + column effect + overall median.
It was developed by using the Beck Depression Inventory (BDI) of 1967 for adults as a model. The CDI is a widely used and accepted assessment for the severity of depressive symptoms in children and youth, with high reliability. [1] It also has a well-established validity using a variety of different techniques, and good psychometric properties ...

[5] The Ryff Scale is based on six factors: autonomy, environmental mastery, personal growth, positive relations with others, purpose in life, and self-acceptance ...
To identify students with learning disabilities through a different lens than the IQ-achievement discrepancy model A study which evaluated the effects of supplemental reading interventions within MTSS and RTI initiatives found that when Tier 2 interventions are implemented with high levels of fidelity, consistency, and intensity, it is possible ...
