This metric captures the volatility in student progression by analyzing the withdraws and major changes, which can indicate structural barriers or inefficiencies in the curriculum. This is most useful to apply to a combination of programs or a unit, like a department or college. There are two coefficients, withdrawn and changed major that can be used to prioritize either of the two causes for turbulence. They are set to 1 and 0.5 by default, respectively.
student_mobility_turbulence(
number_withrawn,
number_changed_major,
total_number_of_students,
withdrawn_coefficient = 1,
changed_major_coefficient = 0.5
)numeric - The student mobility turbulence
numeric - the total number of students who dropped out of a program in a given unit
numeric - the total number of students who changed majors in a given unit
numeric - the total number of students in a given unit starting at a specific time
numeric - a coefficient weighting the number of students who dropped out
numeric - a coefficient weighting the number of students who changed majors out
