In Terms of Stimulus Scaling, Explain What It Means for a Scale

Question

Examlex · Accepted Answer

The Answer is In stimulus scaling, a scale is said to be of interval quality when it has equal intervals between the points on the scale, and the zero point is arbitrary. This means that the distances between the points on the scale are consistent and can be measured in equal units, but the zero point does not have any inherent meaning.

The key features of an interval scale in stimulus scaling include equal intervals and the ability to perform mathematical operations such as addition and subtraction. This means that the distance between any two points on the scale is consistent and can be quantitatively measured. For example, on a temperature scale, the difference between 20 and 30 degrees is the same as the difference between 70 and 80 degrees.

However, there are also key features that cannot be achieved with an interval scale. One such feature is a true zero point. An interval scale does not have a true zero point, meaning that the zero on the scale does not indicate the absence of the measured attribute. For example, on a temperature scale, a reading of 0 degrees does not mean that there is no temperature, it simply represents a point on the scale.

Another key feature that cannot be achieved with an interval scale is the ability to perform meaningful ratios. Because the zero point is arbitrary, it is not possible to make meaningful comparisons in terms of ratios. For example, on a temperature scale, it would not be accurate to say that 40 degrees is "twice as hot" as 20 degrees, as the zero point is arbitrary and does not represent the absence of temperature.

In conclusion, while an interval scale in stimulus scaling has the key features of equal intervals and the ability to perform mathematical operations, it lacks a true zero point and the ability to make meaningful ratios, making it limited in certain aspects of measurement.
