Q1.What is an example of data that can be transformed from one level of measurement to another and another example of data that cannot be transformed?
Validity -Examples
Transformation of data rectifies deviation from uneven variance and normality (heteroscedasticity). Correct transformation facilitates in using parametric statistics.
For data transformation, those methods can be used, like Rank-Based Method that does not require assumptions. We can also transform data mathematically in order to make adequate and in alignment with assumptions before analysis.
