In this investigation, students are able to determine simple harmonic motion with real-life examples and obtain a graph of the sinusoidal function. The graph allows students to determine period and frequency as well as the value of acceleration due to gravity.

When the parameters in the sinusoidal function are estimated, then the cycle or period ([OMEGA]) can be computed as [OMEGA] = [absolute value of 2[pi]/[rho]], if 0 < [rho] < 1 (Brockwell & Davis 2010).

Fitting a sinusoidal function to the daily and seasonally grouped MDT data resulted in a good correlation quantified by the squared Pearson correlation coefficient ([r.sup.2]) and root-mean-square error (RMSE): (i) seasonally grouped data: [r.sup.2]= 0.9821, RMSE = 50.25, and (ii) daily grouped data: [r.sup.2] = 0.4885, RMSE = 26.21.
