This question could be answered in a variety of ways. In statistics for the biological sciences we use scales of measurement for variable types. In this case there are 4 types of variables: nominal (aka categorical), ordinal, interval (aka scale), and ratio.
Identify the four levels of measurements?
lNonmetriclNominal - size of number is not related to the amount of the characteristic being measuredlOrdinal - larger numbers indicate more (or less) of the characteristic measured, but not how much more (or less).lMetriclInterval - contains ordinal properties, and in addition, there are equal differences between scale points.lRatio - contains interval scale properties, and in addition, there is a natural zero point.
What is the theoretical background of measurement?
Measurement is based on several tenets: Interval, quantitative value, and relative baseline. Interval means the measurement cannot be based on ordinal values as they have no interval. EX: There is no interval between first place and fourth place. Quantitative means qualitative values, like orange, smooth, and such, cannot be used to measure. Numbers or number equivalents have to be used. Relative baseline means there has to be a "measuring stick" against which the measurements are made. Some sort of standard, like the metric system standards liter, meter, and second.
What are four types of variables that are commonly used?
Four commonly used types of variables are: Independent Variables: These are manipulated in experiments to observe their effect on dependent variables. Dependent Variables: These are measured outcomes that are affected by changes in independent variables. Control Variables: These are kept constant to ensure that any observed effects are due to the independent variable. Categorical Variables: These represent distinct groups or categories, such as gender or color, and can be nominal or ordinal.
