Shipley developed a NEW test to measure IQ. Using his test, someone with an IQ of 180 would be considered twice as intelligent as someone with an IQ of 90 and someone with an IQ of 90 was three times as intelligent as someone with an IQ of 30. Shipley's test treats IQ as a(n):________.

Based on the information provided within the question it can be said that in this scenario Shipley's test treats IQ as a ratio variable. This means that it any two of the values used have meaningful ratio, allowing for the use of multiplication or division. For example if someone with an IQ of 90 was three times as intelligent as someone with an IQ of 30 it means that individual A's IQ (90) divided by 3 would equal the IQ of individual B (30).

The ratio variable is defined as the variable having all the properties of the interval variable.

In the data given, Shipley's test for IQ is considered as a ratio variable.

Ratio variable is quantitative data, in which the difference between the measurements is taken and the true zero exists. An example of a ratio variable is the measurement of temperature on a Kelvin Scale.

In the data given, Shipley measures the IQ scores as the difference between values, such that a person with IQ 180 will be considered twice as intelligent as the other person with an IQ level of 90.

Thus, the correct answer is the ratio variable.
