In addition, percentage foreign-born and percentage teaching hospitals were highly correlated (r = 0.30).
†Logistic regression used for dichotomous hospital characteristics (for example, percentage teaching hospitals), and linear regression for continuous variables (for example, patient's age), treating the hospital fifths as a continuous variable and controlling for clustering within hospitals.
For example, out of the 384 PI users surveyed by Mazur and colleagues, 67% taught at universities, 19% taught at 4-yr colleges, 5% taught high school, and smaller percentages taught at other institutions, such as 2-yr and community colleges (Fagen et al., 2002).
Both sides said it was hard to estimate what percentage of teaching assistants refused to teach their classes because most of their classes are scheduled for late in the week.
To avoid collinearity and create a more robust model, poverty rate was dropped from the final multivariable regression model; percentage of teaching hospitals was dichotomized, assigning a value of 1 to states with 5% or more teaching hospitals.
In addition, the association between multiple job-holding and working-time percentage in teaching was considered.
On the basis of this consideration, we decided not to include job percentage in teaching into our model.
For each of the five semesters, we looked at the percentage of teaching and learning responses coded as student ideas in week 2 relative to the percentage of responses coded as the concept in week 15 (Fig. 5).
In our study the students of teachers that had the highest percentage of teaching time using centralized concepts either did not improve on questions involving variation or their scores were lower between the pre-test and post-test.
Percentage of teaching hospitals greater than 5% was found to be a weak predictor of uncompensated care, but was not significant (P =.601).
We found no relationship between the following market characteristics and cesarean section: average malpractice payments, number of hospital births, percentage of teaching hospitals, percentage of small hospitals, percentage of for-profit hospitals, OB beds per 1,000 capita, neonatal ICU beds per 1,000 capita.
