Question

an epidemiologist wants to investigate attitudes towards climate change in high school students. he conducts a study at palm springs high school in tampa, fl. he then samples students from freshman year through senior year. a frequency histogram is shown below. what type of variable is student year (freshman, sophomore, etc.)? dichotomous continuous ordinal categorical

Explanation:

A dichotomous variable has two categories. Student year (Freshman, Sophomore, Junior, Senior) has more than two categories, so it's not dichotomous. A continuous variable can take on any value within a range, which doesn't apply here. An ordinal variable has categories with a natural order, and student year does have a natural order (Freshman < Sophomore < Junior < Senior). A categorical variable is a general term for non - numerical variables, and ordinal variables are a type of categorical variable. But since there is a natural order, the most specific and correct type is ordinal.

Answer:

C. Ordinal
