The motivated student may go on to find appropriate learning resources but in a typical clerkship there is considerable variability in the quality of the student's search and in the resources available [ 10, 11].
To account for this dependence, we include a random effect in the regression model for instructor, which aims to capture the variability in student responses not attributable to the variables in Table 1, but which may be the result of students having the same instructor.
This suggests that among students in grades 1 to 4, school-level differences did not account for a significant amount of the variability in the odds of a student being obese versus a normal weight.
Among students in grades 1 to 4, significant between-school random variation in the odds of being overweight was identified [σμ0 = 0.274 0.106), p < 0.001]; school-level differences accounted for 7.7% of the variability in the odds of a student being overweight versus a normal weight.
There is a need, then, for alternative success measures for universities serving students with variable enrollment patterns and great variability in their student populations.
Rovai, Wighting, Baker, and Grooms (2009), based on the meta analysis of 232 comparative studies performed by Bernard et al. (2004) indicated that there is a broad variability in the results achieved by students on distance (online) learning courses and classroom courses.
There was more variability in the component scores of students who hadn't taken a quantitative module in their primary degree compared to all other subgroups (Table 1).
We considered this improbable because of the lack of variability in the routine of undergraduate students, who attended the same classes and ate in the same campus dining halls each week.
The samples were collected prior to the beginning of the school day to limit the variability in activity among the students.
The variability in student enrolments on programmes, and features of academic life such as sabbaticals and research leave for permanent staff, mean that fixed-term opportunities to teach, generally for a year or a semester, are made available".
