Nelson (1989)7 quanti?ed the "cold cranking power" of ?ve different battery types in terms of the number of seconds that a particular battery generated its rated amperage without falling below 7.2 volts, at 0oF. The experiment was repeated four times for each battery type and the resulting data set is shown in the following table.

Is there any suggestion of "descriptive" (as opposed to "inductive") evidence in this data set to support the postulate that some battery types are better than others? Which ones appear better? (More precise "inductive" methods for answering such questions are discussed in Chapters 15 and 19.)
