Use the dataset below for Sections A, B and C

The datablock below shows the data for 3,050 speed cameras in the UK.

Every row in the datablock is a different camera. For each camera there is the following data:

Component |
Description |
column |

ID | a number from 1 to 3,050 | A |

Partnership | The police district which operates the cameras. There are 23 different partnerships in the datablock, listed alphabetically | B |

Installation Type | Cameras installed prior to 2002 are listed as ‘Pre’ and those from 2002 onwards are listed as ‘New’ | C |

Camera Type | There are three types of camera; ‘Fixed’, ‘Mobile’ or ‘Red Light’ (meaning at a set of traffic lights) | D |

Location | A brief description of where the camera is located, usually in terms of a road and town | E |

Speed Limit | The speed limit, in mph, of the road where the camera is located. Most cameras are either 20, 30, 40, 50 , 60 or 70 mph but some cameras are located at junctions so have dual speeds, such as ‘30/40’ | F |

Date Installed | When the camera was installed | G |

KSI (3yr average) | The number of illed and Keriously Snjured in accidents at the camera ‘site’, over a 3-year period, expressed as an average per yearI |
H |

Year | The year the camera was installed. A formula based on the date in column G | I |

*Note*

*Note*

* Note 1: *Only the first five cameras, and the last five cameras are presented in the screenshot above. The other rows of the datablock are currently hidden

* Note 2: *All data within the datablock is pure data

*column I which is a formula*

*except** Note 3: *Column B of the datablock does not contain any blank cells

* Note 4: *However, other columns may contain blank cells, or other text such as “unknown” or “missing”

* Note 5: *All cells that appear as a number (e.g. Speeds, KSI or Year) are all formatted as numbers

**For each question in Section A present a single formula. **

**If you present more than one formula, then only the first one will be marked. **

**Question 25 **

**Question 25**

A macro has been created to ** copy **the data from the main datablock onto

**, one for each Partnership, so that each datasheet stores the camera data for just that Partnership.**

**23 individual datasheets**All 23 datasheets have already been created but are currently ** empty**, apart from the headings in row 10 – see the screenshot below.

Every individual datasheet is ** identical**, as below, apart from the name of the sheet, which is the name of the Partnership; Avon, Bedford, Cambridge and so on, as they appear in column M of the summary table.

##### The main datablock is held on a sheet called data.

However, due to errors in the main datablock the macro also has to make the following 2 ** alterations **to the data stored on the

**– but**

**individual datasheets****alter the data in the main datablock.**

**does not**- If the value in the Year column (column I) is prior to 2002 then the Installation Type (column C) must be set to the text “Pre”.
- If the value in the Speed Limit column (column F) is either blank or a zero value then replace this with the text “unknown” and count how many times this has occurred for each Partnership. Present the answer in a message box formatted like this one:

The macro presented below will ** not **produce the desired results as it has some

**in the code, which will cause the macro to either crash, or not produce the correct outcome.**

**mistakes**##### Identify **5 **separate mistakes and for each ‘mistake’:

**5**

- Identify the line of code by number (1 – 33)
- Identify the specific code which causes the error
- Provide the correct version of the code, or describe the solution to the mistake

* Note 1*: a line may contain more than one mistake.

* Note 2*: only the first 5 mistakes presented will be marked. Any other mistakes presented will be ignored. (25 marks)
