Equal intervals and an absolute zero point that indicates the absence of the variable being measured are both part of variables.

The answer is "Ratio variables". Ratio variables are the variables that have both equal intervals and an absolute zero point that indicates the absence of the variable being measured.

The type of variables that have equal intervals and an absolute zero point indicating the absence of the variable being measured are called "Ratio Variables".

Here's why:

1. Variables in statistics can be classified into different types: Nominal, Ordinal, Interval, and Ratio. Each type of variable has specific properties that set them apart.

2. Ratio variables have all the properties of nominal, ordinal, and interval variables. They have a clear definition of zero. When the variable equals zero, there is none of that variable. Variables like height, weight, enzyme activity are examples of ratio variables.

3. Ratio variables also have equal intervals. This means the difference between two values is meaningful. For example, the difference in weight between 100 lbs and 200 lbs is the same as between 200 lbs and 300 lbs.

So, the variables that have equal intervals and an absolute zero point are Ratio Variables.
