Determine the taxonomic measure of Hellwig's development and assess the quality of life in any 8 countries. For this purpose: Choose any five characteristics that you consider appropriate to describe quality of life. Describe the features you have chosen, calculate their mean, standard deviation, and coefficient of variation. Interpret this data. Calculate the measure of Helwig's development. Create a country ranking. The aim is to check how the quality of life in these countries changes over time. That is why you need to create a ranking, for example, in 2015 and in 2022 and compare what changes have taken place.
