Aufgabenstellung
Zu beurteilende Tabelle
Critics & Changes
White space
The used white space doesn't sufficiently group the data objects that belong together. The horizontal white space between the grouped columns beneath the spanner headers is variying and it is too less to visually track across them.
- White space between grouped columns has been adapted and sized evenly to improve the arrangement of them for a better visual perception. Inside grouped columns white space has been reduced to intensify the visual perception as a group (Gestalt principle of proximity).
Title
The title contains dispensible information which is already visible in the different table headers.
- Title has been reduced to sufficiently describe the table.
Subheaders & Arrangement
The arrangement of the subheaders breaks up the data and disrupts the flow of information and makes it hard to read and recognize the differences.
- Subheaders have been moved to a separate column on the left. By adding this mechanisms the legibility of the table increased. Additional white space between each group proofed also helpful to improve the clarity of the table.
The boldfacing of the mechanisms is an unecassary emphasis and is a not useful method to group data.
- Boldfacing has been removed.
Numbers & Alignment
Columns contain data with a varying numeric precision. This disrupt the visual structure of the columns in form of creating ragged edges on the right of a column.
- To facilitate comparison of numbers in columns and to preserve the visual structure of columns (Gestalt principle of enclosure) numbers have now equal number of decimal digits with same alignment down the columns. A numeric precision level of 5 decimal digits has been set to not exceed information with too excessive level of precision. The column headers also have been aligned with the associated data.
Descriptions
The abbreviated row headers Comp and Impu are not consistent with the title and are not convenient describing the use of CRs only and the proposed method.
- The use of the abbreviations CR to describe the use of CRs only and prop to describe the proposed method link to the used methods in a more intuitive manner.
The arrangement of the rows Comp and Impu isn't handy to recognize that there is less difference between Full and Impu than between Full and Comp.
- Therefore the rows have been arranged in such order to be unterstood more easily. The row prop has been placed above the row CR.
