Sally created a survey to determine professional development needs of the stage 2 and 3 teachers.She asked all the teachers to complete the survey.Which statement below best describes the variables used in the survey?Question 3Select one:A.The variables are qualitative nominal.B.The variables are qualitative ordinal.C.The variables are quantitative interval.D.The variables are quantitative ratio.

Without knowing the specific questions asked in Sally's survey, it's difficult to definitively identify the type of variables used. However, I can explain what each type of variable means:

A. Qualitative nominal variables are categories that do not have a natural order or ranking (e.g., types of fruit: apples, oranges, bananas).

B. Qualitative ordinal variables are categories that do have a natural order or ranking (e.g., education level: high school, bachelor's, master's, doctorate).

C. Quantitative interval variables are numerical and the difference between values is meaningful. However, there is no true zero point (e.g., temperature in Celsius or Fahrenheit).

D. Quantitative ratio variables are also numerical, the difference between values is meaningful, and there is a true zero point (e.g., height, weight, age).

If Sally's survey asked teachers to rank their need for professional development in different areas, then the variables could be considered qualitative ordinal. If she asked them to rate their need on a numerical scale, then the variables could be considered quantitative interval or ratio, depending on whether there's a true zero point.
