| ===Critics on the table===
| |
| * The titel doesn´t contain of which year(s) the Top 25 is and you don´t know which period of the year is used. Because the reference source is from March 2007 and it is not possible that the "whole" years 2006 and 2007 are compared.
| |
| * The table shows the Top 25, but from the the way the lines are ordered its not easy to get the rank for example the Top 7. Further it´s not easy to follow the horizontal line, because there are grids and rules missing.
| |
| * The mean of the colum "Increase/Decrease" is not clear, what shall it mean?
| |
| * In the colum "Percent" after every data the symbol % is missing and only in some cases a decimal place is published.
| |
| * The column "2006" and "2007" is not in chronological order.
| |
| * The subtitle electronic editions is used two times.
| |
| * A comma is placed to the left of every three digits of numbers and the data aligne centered. So the direct comparison with the other lines is not possible - you get an false impression of the size of the number.
| |
| * Because of the way numbers are written and read, aligning them to the left or
| |
| center makes them difficult to interpret.
| |
| * The column “-Frequency” is not important because there is only one exception.
| |
| * It is difficult to track across the rows with this spacing.
| |
| * The name of the district is just published in same cases.

| ===Which changes have been made? Why is the changed one better than the original table?===
| |
| *Titel sollte sich aufs Jahr beziehen – Top 25 (2007); weiters bezieht es sich auf USA oder ? => Top 25 USA Newspaper … 2007
| |
| * 2006/2007 im Titel, damit Vergleich klar
| |
| *bei Prozent + oder -
| |
| Nicht nur Prozent sondern auch % (Symbolkraft,visuelle Typen)
| |
| Place a percentage sign (i.e., %) immediately to the right of every percentage value (e.g., 8.75%).
| |
| * Negative Zahlen in Klammer ? (+- oder rote, grüne Schrift)
| |
| * gemeinsamer Header (Unterpunkte 2006/2007)
| |
| * grau, weiß horizontale Aufmerksamkeit auf Zeile und nicht auf Spalte!!!
| |
| Because we don’t want to suggest that the names of the months or the totals are
| |
| more important than the other data, I’ve used a subtle fill color.
| |
| *Störend dass zuerst 2007 dann 2006 – um drehen zuerst 2006 und dann 2007 (chronologische Reihenfolge) – Lesefluss von links nach rechts
| |
| chronological order of dates and times.
| |
| *Zahlen rechtsbündig, mit , für Tausenderstellen bzw. gleiche Anzahl an Nachkommastellen
| |
| * Highlights setzen? Mit Zellenhintergrundfarbe oder mit Schriftfarbe
