- systematic sampling
Systematic sampling is where follows of a certain pattern through out the collection of data is taken by with from a starting point and t hen at regular intervals. For example in order to take the housing value we took the amount of houses on both sides of the road and if there were 50 houses in total we would record data form the fifth house along.
- stratified sampling
Stratified sampling is where the sector which is being examined is split up into groups or areas and the data is then recorded. For example the housing age was taken using this method as we split up the houses into three classes Victorian, Modern and interwar. We then collected the data according to this.
Housing Type
In order to take the age of a certain house we divided the houses into three types:
Victorian
To determine whether a house was Victorian we based it on certain characteristics such as they have “bay” and “sash” windows, of which the glass is in some parts usually stained, styled brick work (that follow a pattern) and sometimes no garage. For example on Coronation Street are all typical Victorian houses.

Taken from:
Interwar
To determine weather a house was from the inter war period we looked at the house to see whether had it had a slated roof, back garden, cramped and triangular shaped roof.
On the right: typical inter war house
Modern
To determine if a house was modern, we examined the house to see if it had modern characteristics such as double glazed windows, a unique design, and many different characteristics.

Environmental Quality
In order to work out the environmental quality of a certain area, we came up with a table which contained different factors on which to base the road on. To asses the road, we stood half way down a street and we took in the results by our own judgement. The table in which we based our results on is shown below.
We added the scores up and they were totalled out of 60 and then the roads were then scheduled into a table of results. The scores are based with high being good environmental quality and low being poor.
Housing Value
In order to work out the housing value we followed the same principles of the environmental quality whereas for the housing value wee walked down the road and took values in which were written on a table from at least six houses per road. The table is shown below. High scores meaning the housing is high and low meaning poor housing value.
The scores were then totalled up and scored out of 40.
Green Space
In order to measure the green space we gathered secondary data from Google earth and other maps and looked for areas which contained environmentally green factors. To measure the distance from the C.B.D we drew rings around the map going out per hundred metres as shown below.
We also followed the same procedure for house prices to show that they increased with distance from the C.B.D.
Traffic density
In order to measure the traffic density in Altrincham, we dropped a pen onto a piece of paper and took traffic counts from where the pen landed. Secondly we collected the data and placed it in a table. The traffic counts were taken from the map shown below.
