Nhich one of the following statements is incorrect? elect one: 1. The method of the payment is a qualitative variable. 2. The rating of a lecturer by the students ( 1 = very effect = effective, 3 = not at all effective) is a qualitative ordinal variable. 3. The marital status is a qualitative variable.

Did you know that qualitative variables are often described in terms of characteristics or attributes rather than numerical values? The method of payment, for instance, can include various options like cash, credit, or digital payment, making it a classic example of a qualitative variable. On the other hand, ordinal variables provide a sense of ranking. For the lecturer's rating, students' responses represent a clear order from "very effective" to "not at all effective," giving valuable insight into performance. It's fascinating how we can categorize data in such meaningful ways!
