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.

Example of data that can be transformed
