Abstract:
Two functional measurement studies were conducted to test the effect of two types of end anchors on the linearity of Visual Analogue Scale (VAS) data. With the first type of end anchors, participants responded to the stimuli using a VAS with predefined end anchors. With the second type, respondents defined the end anchors in terms of their own assumptions, perceptions, goals and values. The results show that VASs can be considered as linear scales and that the type of end anchors used has no effect on the linearity of the VAS data.

Ordinal Level of Measurement
Data measured using an ordinal scale are similar to nominal scale data, but there is one major difference. The ordinal scale data can be ordered. An example of ordinal scale data is a list of the top five national parks in the...
Interval Level of Measurement
Data measured using the interval scale are similar to ordinal level data because they have a definite arrangement. However, in the interval level of measurement, the differences between data values are meaningful even though the data does not have a starting point.
Temperature is measured using the interval scale. It is measurable data, and the difference between the...
Ratio Level of Measurement
A set of data measured using the ratio scale takes care of the ratio problem and provides complete information. Ratio scale data are like interval scale data, except they have a zero point and ratios can be calculated. For...

Homogeneity dictates that if an input x(t) is multiplied by a constant c, the output y(t) is multiplied by the same constant. Mathematically, this is expressed as:
