Question

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. What are the cases in these records?

Answer 1

Explanation:

Qualitative variables are variables that describe the characteristic or attribute which has distinct categories. That is, these variables can be divided into two or more groups based on the characteristic. For example, if the subjects are classified based on the literacy rate, then the literacy rate is a categorical variable.

Quantitative variables are variables that record a numerical quantity That is these variables can be counted or measured. Age of people, heights of students, land area are some of the examples for quantitative variables.

The variables ‘Reading Test Score, Age, Mathematics Test Score, Days Absent’ are the quantitative variables because they cannot be counted nor divided into different groups.

From the information, the State Education Department has maintained the records for keeping the information about the students related to race or ethnicity.

The variable ‘Race or Ethnicity’ is a qualitative variable because it describes the characteristics of the variable race and ethnicity which is divided into different groups.
