Aufgabenstellung
Original table
Critic on original table
Even the table seems to be structured it is difficult to compare the data. The vertical lines and the unsteady intervals between the horizontal lines make it difficult to group the data intuitive.
Missing unit in expenditure columns.
Redesigned table
Changes applied to table
Second row, the one with ordinal numerals had no meaningful function. Because of that we decided to remove it completely from the table.
It is a convention that numbers are aligned to the right. When the numbers in column are displayed with the same precision, i.e. two decimal places like in this table, reader can more easily compare numbers one under another because hundreds are under hundreds, thousands under thousands and so on.
There should be units declared for each column at least in header. However there were no units declared in original table so we cannot say what currency is the amount displayed in. However there was added % sign to each cell in percentage columns. It is a convention too. Reader sees that the number describes percentage without looking into header row.
We changed also a format of the numbers, to make processing and comparing of numbers easier for reader. Comma was placed to the left of every three whole-number digits to divide thousands from millions, millions from billions, etc. Reader can more easily count digits in the number.
Another change we made is addition of "Education type" into header row and removing of word "Education" from each row in first column. Thus the cells are shorter and don't have to be wrapped to two or more lines because of redundant information. Each line has now the same height.
Almost all rules were removed. They remained only on places where they are used to divide header or summary from the rest of data. After removing of rules we got body of table without any guideline in which direction data should be read. Because of that we decided to use light background color for columns. Reader can now easily compare expenditures for each type of education and find the results for each row and each column.
