Labels:text | font | screenshot OCR: b. If the data points are plotted and joined by line segments, we get a graph demonstrating data fluctuations. Normally, what is of interest is the underlying smooth curve (hence the term suunothing ) for this process. Compare the graphs of the unsmoothed data and the smoothed data for n = 2. Solution: Fig. 2.5 (see next card) shows the plot of the unsmoothed data (solid line) and the data smoothed with n = 2 (broken line).
