Stevens, and it seems no accident that it remains much mentioned by some psychologists, It is of some use as terminology, but little as a scheme for prescribing or proscribing which methods to use. Whether a scale has a true zero has some bearing on explaining e,g, why the coefficient of variation may be useless or misleading. As a more common issue, the idea that you shouldn't take means of ordinal variables is exaggerated; just take those means if they help analysis. | |

However, polytomous categorical variables (i.e., those with more than two levels) are clearly not continuous." | |

| Jun 11, 2024 at 11:07 | comment | added | Peter Flom | That sounds wrong. What book was it? Can you give us more of the quote? Maybe there is some context that makes it sensible. (Also, dichotomous variables are easily handled in multiple regression, but not because they are continuous). (The quote may be a typo .... I've edited a couple textbooks and typos are quite common). | |
