A student measures the range of sound frequencies that the human ear can hear by playing sounds for volunteers between 10 and 30,000 hertz

B. Ordered

Explanation:

we found complete question that is: A student measures the range of sound frequencies that the human ear can hear by playing sounds for volunteers between 10 and 30,000 Hertz and asking them to raise their hand if they were able to hear it. What type of variable is the independent variable in this experiment?

A. Categoric , B. Ordered ,  C. Continuous , D. Discrete

solution

Volunteers between 10 and 30,000 Hz ask the human ear to raise their hand when the student is measuring the range of sound frequency and if they can hear it; This requires consistent answers from the experiment participants on whether or not they can hear the sound. Therefore, the category can be classified under the ordinal category ordered.

as eg. Highest Education Level has variable Elementary School, High School, many College and College Graduate
