Interpretation is based on the minimum number of correct responses required for significance at a predetermined significance level, given the total number of responses received. The minimum number of correct responses may be found in statistical tables provided in several publications (ASTM, 1968; Meilgaard et al., 1991; Stone and Sidel, 1985).

How many data points are enough?: As an answer to the initial question, a simple and fast rule for introductory labs would be to collect 6 data points minimum. This is, admittedly, an arbitrary number but one that seems to work well in the introductory setting. The selection of the data points must take into consideration the following:

By fixing a significance level (0.05) we can produce an effective test to eliminate classifiers that are not significant from the fitting of the learning curve. Since the classifier performance usually improves with increasing training set size, this significance test also allows us to find the minimum …
