Description of the second exercise (German)

The Original Table

Critique of the Given Table

  • It is not apparent for which region this statistic was made
  • The table lacks a concise and meaningful title, which would offer the reader a short description of the table
  • The table reflects various contexts:
    • The absolute number of the employed people in various industries
    • The absolute number of the unemployed people and the unemployment rate
    • The labour force participation rate
    • The absolute number of the people who are not in labour force
  • The subgroups aren't comparable due to the differing contexts mentioned above
  • Mixed percentage and absolute values (row- and column-wise)
  • References to so-called "units" for percentage values
  • The lack of percent signs for percentage values, which would make the cognition of the percentage values easier
  • The alignment of the columns suggest constant time intervals between the time instants
  • The age ranges are inconsistent and therefore not comparable
  • Inconsistent row headers (e.g. "Employed, total" and "Unemployed")
  • Inconsistent declarations for age ranges ("years of age" and "of those aged")
  • Inconsistent date declaration for the column header "CHANGE"
  • Inconsistent formatting (block letters, various text alignments, italic type, etc.)
  • Too little vertical whitespace between rows

The Revised Table

Description of the Undertaken Improvements

  • A concise and meaningful title has been added, which offers the reader a short description of the table
  • The varying contexts or rather groups have been separated more clearly by applying bold row headers and alternating the fill color
  • The declarations of the rows have been put in a designated column to separate the groups more clearly and to enhance readability
  • Misleading references to "units" have been removed
  • Percentage signs have been added to denote percentage values
  • Special considerations have been made regarding the consistency of row headers, declarations, date formats and text formatting to enable fast processing of information
  • The years in the header have been aggregated to avoid distracting redundancy
  • A different font and more vertical whitespace have been used to increase readability
  • The number of lines has been reduced to avoid distraction from the content
  • A comma have been placed to the left of every three whole-number digits
  • Sums and summarizing values have been placed at the bottom of each group
  • Missing values have been calculated wherever possible
