Select all correct answers.1.Reading Test Score2.Race or Ethnicity3.Disabilities or Special Needs4.Age5.Mathematics Test Score6. Days Absent7.Current Grade Level

Answer 1

Answer:

2.Race or Ethnicity

3.Disabilities or Special Needs

7.Current Grade Level

Step-by-step explanation:

A Categorical variable is a non numerical variable, and usually is defined as "a variable that allows to assign categories but we cannot clearly order the variables".

If a variable is not Categorical can be ordinal or or numerical.

Ordinal when we can create a order from the data. And numerical when is not categorical or ordinal.

1.Reading Test Score

False, usually the scores are quantitative or numerical variable since are measured on units..

2.Race or Ethnicity

True, is categorical variable since we don't have an order for this.

3.Disabilities or Special Needs

True, we can consider this variable as categorical since we don't have an order and can't be expressed in numerical terms.

4.Age

False, is a quantitative variable or numerical

5.Mathematics Test Score

False the scores represnt a numerical variable.

6. Days Absent

False, that can be considered as quantitative if we count the days absent

7.Current Grade Level

True. That can be considered a categorical variable since we can't express this variable with numbers.

So then the correct choices are:

2.Race or Ethnicity

3.Disabilities or Special Needs

7.Current Grade Level
