Let rate of change in enrolment be Δ E / Δ t. e = enrolment and t = time in years.
Rate of changes per year are:
1970-75 = (14.3 - 13.3 / 5) = 0.2
75-80: (13.2 - 14.3)/5 = -0.22
80-85 = (12.4-13.2)/5 = -0.16
85-90 = (11.3 - 12.4) / 5 = 0.22
90-95 = (12.5-11.3) = 0.24
95-00 = (13.5 - 12.5)/5 = 0.2
take absolute values when comparing the rates.
rate of change is greatest in 90-95 period.
it is least in 80-85
When the slope is negative, it means that the enrolment is decreasing during the 5 year period. So the enrolment decreased during 1975-90 period.
