Final answer:
In a simple experiment with a nominal scale for the independent variable and an ordinal or ratio scale for the dependent variable, nominal data is qualitative and cannot be ordered, whereas ordinal data can be ordered without measurable differences, and ratio data has a meaningful zero allowing for ratio calculations. Therefore, the correct answer to the question is: The IV is on a nominal scale of measurement and the DV is on an ordinal or ratio scale of measurement.
Step-by-step explanation:
The levels of measurement in an experiment are crucial for determining the correct statistical procedures. In a simple experiment, if the independent variable (IV) is measured on a nominal scale and the dependent variable (DV) is measured on an ordinal or ratio scale, it signifies different things. The nominal scale is qualitative and consists of categories that can't be ordered or used in calculations. In contrast, the ordinal scale consists of data that can be ordered, but the differences between them cannot be measured, while the ratio scale includes data that can be ordered, the differences measured, and has a meaningful zero point allowing for calculations of ratios.
Therefore, the correct answer to the question is: The IV is on a nominal scale of measurement and the DV is on an ordinal or ratio scale of measurement.
