SOCIOLOGY

Go back to the variables you identified in #2 above

#2 Assume researchers want to know whether first-born children learn to speak at a younger age than second-born or third-born children. Answer: Researchers want to know whether first-born children learn to speak at a younger age than second-born or third-born children. In this example, the dependent variable is the age at which the child learns to speak, and the independent variable is whether the child is first or second born.

Identify and define the level of measurement for the independent variable (IV) and (DV) dependent variable.

Answer #1

The level of measurement for the IV is ordinal scale. Since we are measuring whether the child is first or second born, we are essentially assessing the rank.

The level of measurement for the DV is age. Age is a ratio scale variable. It is represented numerically and has a true zero.
