Which type of data (discreet, continuous, nominal, ordinal) from each of the following survey question are collected a) Name your favorite pet? b) How many times did you change your residence in the past five years? c) How do you like math, choose (0= not at all, 1, 2, 3, 4, 5 = very much) d) How tall are you? e) The number of bedrooms in a house

a) The name of my favorite pet is only a "label" between the set of different names, in general there is no order, i.e., objectively we can't say that one name is better than other.

b) To find this answer we should do a counting process, i.e., if a random variable represents the number of times that I changed my residence in the past five years, possible values are 0, 1, 2, ...

c) Here we can say there are levels of preference, we can observe an order, but we can't measure the distance between different levels of preference.

d) To obtain an answer to this question we should do a measurement process, instead of a counting process, that is why this kind of data is continuous. A possibility could be for example 1.75m (m=meters), in other words, the random variable associated to this question can take any value in an specified interval.

e) Here we can get an answer through a counting process again, in other words, if Y is a random variable that represents the number of bedrooms in a house, in theory, Y can take the values 0, 1, 2, ...
