| Topic | Data representation |
| Type | Misinterpretation of data in graphs |
| Difficulty | Easy -1.8 This is a straightforward data interpretation question requiring only basic observation of changes in tabular data. Students need to identify which numbers increased/decreased significantly between years - no calculations, statistical concepts, or mathematical reasoning required. This is well below typical A-level maths standard, being more akin to GCSE data handling. |
| Spec | 2.01b Informal inferences: from samples2.02a Interpret single variable data: tables and diagrams |
| Local authority (LA) | All people in employment | Underground, metro, light rail, tram | Train | Bus, minibus or coach | Motorcycle, scooter or moped | Driving a car or van |
| LA1 2001 | 79226 | 14369 | 5235 | 20575 | 1227 | 16052 |

| Answer | Marks | Guidance |
|---|---|---|
| LA4 | B1* | Not eg "LA4 or LA1", but allow "LA4 and possibly LA1, but less likely"; Dep 1st B1* |
| Large increase in numbers travelling by tram etc or Increase in tram etc greater than the others or There was an increase from \(65\) to \(2495\) | B1 [2] | Allow any description of "tram etc"; No need to mention "tram" if clear |
| Answer | Marks | Guidance |
|---|---|---|
| Ratio for bus is approx same as ratio for all people or Recognition that total number has increased | B1* | Must include comment on total number; Must refer to data in table; Not "Bus growth is greater than other forms of transport" |
| No reason to suggest new bus routes | B1 [2] | Dep 1st B1*; Ignore "True.... but possibly not true...": ignore the first part |
| Answer | Marks | Guidance |
|---|---|---|
| LA1, because: decrease in number driving cars | B1 | Must state LA1, but no mark for this yet |
| despite increase in total number of people or all other LAs had increased numbers driving or \(\geq 2\) LA1 public transport categories increased | B1 [2] | eg LA1 is the only LA with decrease in driving: B1B1; Ignore all else |
## Question 10:
### Part (a):
LA4 | **B1*** | Not eg "LA4 or LA1", but allow "LA4 and possibly LA1, but less likely"; Dep 1st B1*
Large increase in numbers travelling by tram etc or Increase in tram etc greater than the others or There was an increase from $65$ to $2495$ | **B1** [2] | Allow any description of "tram etc"; No need to mention "tram" if clear
### Part (b):
Ratio for bus is approx same as ratio for all people or Recognition that total number has increased | **B1*** | Must include comment on total number; Must refer to data in table; Not "Bus growth is greater than other forms of transport"
No reason to suggest new bus routes | **B1** [2] | Dep 1st B1*; Ignore "True.... but possibly not true...": ignore the first part
### Part (c):
LA1, because: decrease in number driving cars | **B1** | Must state LA1, but no mark for this yet
despite increase in total number of people or all other LAs had increased numbers driving or $\geq 2$ LA1 public transport categories increased | **B1** [2] | eg LA1 is the only LA with decrease in driving: B1B1; Ignore all else
---10 The table shows extracts from the "Method of travel by LA" tabs for 2001 and 2011 in the large data set.

\begin{enumerate}[label=(\alph*)]
\item In one of these four LAs a new tram system was opened in 2004.
Suggest, with a reason taken from the data, which LA this could have been.
\item Julian suggests that the figures for "Bus, minibus or coach" for LA1 show that some new bus routes were probably introduced in this LA between 2001 and 2011.
Use data from the table to comment on this suggestion.
\item In one of these four LAs a congestion charge on vehicles was introduced in 2003.
Suggest, with a reason taken from the data, which LA this could have been.
