Question

Options

• CInfinite number of numeric values, such as 0.100, 42.001, 1000.743..

  84% (26)

Explanation

We address two cases of the target variable. The first case occurs when the target variable can take only nominal values: true or false; reptile, fish: mammal, amphibian, plant, fungi. The second case of classification occurs when the target variable can take an infinite number of numeric values, such as 0.100, 42.001, 1000.743, .... This case is called regression.
