Variables are like test or scale scores are generally known as interval level variables.

Variables like test or scale scores are generally known as interval-level variables. True or False?

the smaller the standard deviation, the less variability there is and the more similar a single variable’s. True or False?

The interval variable is a measurement variable that is used to define values measured along a scale, with each point placed at an equal distance from one other.

It is one of the 2 types of numerical variables and is an extension of the ordinal variable.

What is an interval level of measurement?
The interval level is a numerical level of measurement that, like the ordinal scale, places variables in order. Unlike the ordinal scale, however, the interval scale has a known and equal distance between each value on the scale (imagine the points on a thermometer).
What is the interval level in research?
Interval scale refers to the level of measurement in which the attributes composing variables are measured on specific numerical scores or values and there are equal distances between attributes. The distance between any two adjacent attributes is called an interval, and intervals are always equal.
