-The standard survey rating scale. -Equidistant points between each of the scale elements (have differences in the distance along the scale). We contrast this to an ordinal scale where we can only talk about differences in order, not differences in the degree of order. E.g: use interval scale to rate people satisfaction, on a 7 point scale, from Dissatisfied to Satisfied. -A scale which are defined by metrics such as logarithms (the distances are note equal but they are strictly definable based on the metric used). statistics: Interval scale data mostly use parametric statistical techniques: -Mean and standard deviation -Correlation -Regression -Analysis of variance -Factor analysis | |||||
