This chart has an unusual vertical scale. Each division is ten times larger than the previous. It is called a logarithmic scale, and is useful when there is a very wide range in values (especially in scientific applications), although it can easily be misinterpreted. In this case, the land area of the ACT is just over one thousand square kilometres, while the land area of WA is well over one million square kilometres. So WA is around $1000$ times bigger.',\n 'Did you study the axes carefully before answering the question? This graph is poorly constructed, as the scale on the horizontal axis is not consistent. LAST YEAR must represent an average of the year, so it is possible that some sales figures for that year were higher than $15$. Therefore we cannot conclude that this week was the best week in the past year.
The purpose of this question is to remind you to read axes carefully. This question is not necessarily a LANTITE style question.',\n 'Did you study the axes carefully before answering the question? The vertical scale on this chart goes to $80$, but no values above $25$ are plotted, so this chart is poorly constructed. It creates a false impression of a relatively flat chart. In reality, the average number of suspensions/year under the first Principal ($17$, $21$, $18$) was almost double those under the second Principal ($10$, $12$, $9$).
The purpose of this question is to remind you to read axes carefully. This question is not necessarily a LANTITE style question.',\n 'The percentages here are the percentage of each year group who have returned their Sports note, NOT the proportion of all students in Years $7$ - $9$ combined. Therefore a pie chart is not the appropriate type of chart. A column graph could be used to show the percentage of each Year group who have returned their Sports note.
The purpose of this question is to remind you to think about the kind of data that is being displayed on the graph. This question is not necessarily a LANTITE style question.',\n 'Did you study the axes carefully before answering the question? The vertical axis on this chart does not start at zero.
