Quizplus · Accepted Answer

Unsupervised data mining involves exploring the data and finding patterns without any prior hypothesis or developed models. The analysts create hypotheses only after performing an analysis, which is why option B is true. Option A is incorrect because the analysts estimate the parameters of a model in supervised data mining, where there is already a developed model. Option C is also incorrect because data miners develop models in supervised data mining. Option D is incorrect because regression analysis is a supervised data mining technique.
