This indicates that the quality of academic service also contributes positively and significantly to student satisfaction. Availability of Facilities and Infrastructure (-0.011), This negative coefficient shows that every one unit increase in the availability of facilities and infrastructure, assuming other variables remain constant, will reduce student satisfaction by 0.011 units, this shows that the availability of facilities and infrastructure is still inadequate, and needs to be improved.
