The State Education Department requires local school districts to keep these records on all students: age, race or ethnicity, days absent, current grade level, standardized test scores in reading and mathematics, and any disabilities or special educational needs the student may have.Which of the following are categorical (or qualitative) variables in these records? Select all correct answers.1.Reading Test Score2.Race or Ethnicity3.Disabilities or Special Needs4.Age5.Mathematics Test Score6. Days Absent7.Current Grade Level

Respuesta :

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

To solve such problems we need to know about Categorical Variables.

Categorical Variables

Categorial variables are those variables that are divided into two or more categories or groups but the data will be fixed and will not fall out of those categories.

For example, the gender of a person can be male, female, or transgender but will not be out of this basic structure.

Given to us,

  1. Reading Test Score
  2. Race or Ethnicity
  3. Disabilities or Special Needs
  4. Age
  5. Mathematics Test Score
  6. Days Absent
  7. Current Grade Level

As we can see the data

  • Race or Ethnicity,
  • Age,
  • Current Grade Level,

These data can be divided into categories. Such as race can be white, black, Asian, etc.; for school, the age of the students is almost close to each other, therefore, age can be categorized, current grade level can be classified as well.

  • Reading Test Score
  • Disabilities or Special Needs
  • Mathematics Test Score
  • Days Absent

The following can not be divided into categories, as for every student the test score can be different, their disabilities or special needs may be different, and the number of days each student is absent is very different. these data may be grouped but creating so many categories will be of no use.
