The difference between interval and ratio data is simple.Ratio data has a defined zero point,whereasinterval data lacks the absolute zero point. Interval datais measured so that each value is placed at an equal distance from one another in a clear order, while ratio data uses absolute zero as...
根据变量可度量程度的由低到高,可将其依次划为 nominal, ordinal, interval, ratio 四种类型。其中,nominal, ordinal data 属于 categorical data,是对对象的一种定性描述;interval, ratio 属于numerical data…
However, unlike interval data, ratio data has a true zero. This basically means that zero is an absolute, below which there are no meaningful values. Speed, age, or weight are all excellent examples since none can have a negative value (you cannot be -10 years old or weigh -160 pounds...

1. An introduction to the four different types of data To analyze any dataset, you first need to know what kind of data you’re working with. Broadly, data falls into one or more of four categories:nominal,ordinal,interval,andratio. These scales, orlevels of measurement, tell us how prec...
Here are some examples of ratio data: Weight, height, or length The temperature in Kelvin (since zero Kelvin means zero heat) Length of time/duration (e.g. seconds, minutes, hours) In all of these examples, you can see that thezero point is absolute. For example, zero seconds quite li...
A ratio variable, has all the properties of an interval variable, and also has a clear definition of 0.0. When the variable equals 0.0, there is none of that variable. Examples of ratio variables include: enzyme activity, dose amount, reaction rate, flow rate, concentration, pulse, weight,...
1.NominalOrdinal Interval Ratio A pie chart displays groups of nominal variables (i.e. categories). Nominal: nominal is from the Latinnomalis, which means “pertaining to names”. It’s another name for acategory. Examples: Gender: Male, Female, Other. ...
（3）Interval Data 定距变量：变量的值之间可以比较大小，两个值的差有实际意义，这样的变量叫定距变量。有时问卷在调查被访者的“年龄”和“每月平均收入”，都是定距变量。（4) Ratio Data 定比变量, 有绝对0点，如质量，高度。定比变量与定距变量在市场调查中一般不加以区分，它们的差别在于...
In contrast, the Kelvin temperature scale is aratio scale. In the Kelvin scale, nothing can be colder than 0 K. Therefore, temperature ratios in Kelvin are meaningful: 20 K is twice as hot as 10 K. Examples of interval data Psychological concepts like intelligence are often quantified through...
