Description: This task shows you how to convert absolute data into relative or percentage data. You start from the data in a table and their representation in a sector diagram, which is usually used to show the relative value of the data. You are shown how to calculate the percentage value for an absolute value: percentage value = (absolute value/total values)*100.
The first part of the task requires an intuitive understanding of this concept. Because logically a greater part or portion of the bar diagram corresponds to a larger absolute value. You can either use the same formula or deduct the relative values of Álava and Bizkaia from 100 to calculate the value for Gipuzkoa. You can also do it in both ways and check that you get the same answer.
