Preceptor Table Model

This page presents a compact preceptor-style summary of the dataset. It includes both a preview of the observations and a variable-level summary drawn from the actual study data.

Data-generating mechanism

The model on this page uses a linear regression framework. In this setting, the exam percentage outcome is treated as being generated by a combination of predictors such as gender, ACT score, age, URM status, class standing, and grading basis, with the relationship described by a linear model.

\[ \begin{aligned} \text{Exams\_percent}_i &= \beta_0 + \beta_1(\text{AGE}_i) + \beta_2(\text{Gender}_{\text{Men},i}) + \beta_3(\text{URM}_i) + \beta_4(\text{COMP\_ACT\_SCORE}_i) \\ &\quad + \beta_5(\text{YearSchool}_{\text{Sophomore},i}) + \beta_6(\text{YearSchool}_{\text{Junior},i}) + \beta_7(\text{YearSchool}_{\text{Senior},i}) + \varepsilon_i, \end{aligned} \]

where

\[ \varepsilon_i \sim N(0,\sigma^2). \]
