STANDARDIZE VARIABLE Meaning and Definition

  1. A standardized variable, often referred to as a standardized score or z-score, is a concept used in statistics and data analysis to transform a set of raw data into a new set of values with a standard deviation of 1 and a mean of 0. It is a way to make different variables comparable and comparable across different datasets. The process of standardization eliminates the units of measurement, allowing for easier interpretation and comparison.

    To standardize a variable, each value in the dataset is transformed by subtracting the mean of the variable and then dividing by its standard deviation. This normalizes the values, making them fall along a standardized distribution curve. The resulting standardized variable has a mean of 0, indicating how far each value is from the mean, and a standard deviation of 1, revealing the relative dispersion of the values.

    Standardizing variables is particularly useful when dealing with datasets that have different scales or units, as it allows for meaningful comparisons between variables. It is often employed in various statistical techniques such as factor analysis, regression analysis, and hypothesis testing.

    In summary, a standardized variable is a statistical transformation of raw data, which adjusts for the original mean and standard deviation to result in a set of values that can be compared, interpreted, and analyzed more effectively.

Etymology of STANDARDIZE VARIABLE

The term "standardize variable" consists of two words: "standardize" and "variable".

1. Standardize: The word "standardize" is derived from the noun "standard", which comes from the Old French word "estandart". In turn, "estandart" is derived from the earlier Frankish word "standhard", where "stand" is related to "stead" (place) and "hard" means "hardship". The concept of standardization arose from the need to establish a fixed measure or criterion against which other things can be compared or evaluated.

2. Variable: The word "variable" comes from the Latin word "variabilis", which is derived from the verb "variere" (to change). It refers to something that is subject to variation, change, or alteration.
