# Are coordinates (e.g. Point(123, -123)) considered interval data?

I understand that latitude and longitude are interval data, but are coordinates (e.g. Point(123, -123)) also considered interval data? If so, how can the standard deviation, mean etc. be calculated?

At its simplest, a measurement on ratio scale is one measured relative to a natural and uncontroversial zero, so that human height and weight are examples and Celsius and Fahrenheit temperatures are not. Loosely, ratios make sense for measurements on ratio scales, so that heights of 2 m and 1 m allow a ratio of 2 to 1 to be calculated and also allow statements such as Joanna is twice as tall as her sun Jim. Conversely, there is no useful meaning to a notion that 20$$^\circ$$C is twice as hot as 10$$^\circ$$C. We could if we wished say that the former is twice as far from 0$$^\circ$$C as the latter, but ratios don't enter into analysis of such temperature measurements. .
