These are routes frequently leading out of the CBD or cutting through the CBD, which allow changes to be seen in an urban area.
Surveys along a transect could include: The same transect techniques could be used to plot information on noise or pollution levels as ENVIRONMENTAL SURVEYS or temperature variations in urban and rural areas.
STRATIFIED This is choosing specific quantities of a population usually based on prior knowledge. Interviewing ten men and ten women as they enter a shop or interviewing a proportion of each age group (below 30, 30-50, 50 plus) as they enter a shop.
In each case you have selected Quotas of each group that you want to talk to.1) QUESTIONNAIRES One way to collect data is to use a questionnaire.
FIELD SKETCHES can be made and labelled appropriately to show key features.
These could be used in both human and physical geography.Data collected during these surveys would be noted on recording sheets or plotted directly onto maps.In all surveys the type of sampling to be done must be considered very carefully.Before a questionnaire is given out it should be tested with a PILOT SURVEY.It should be tested on a small number of people to find out if any questions are unclear and need to be changed.Closed questions offer a limited number of responses.It is often easier to analyse data collected from closed questions. How long did it take you to travel to the shopping centre?2) OBSERVATION A second way to collect data is by simple observation.Here information can be collected in a variety of ways.The last paper of the Geography exam will test your practical geography skills.The paper is one hour 45 minutes in length and will consist of two questions, one based on physical geography and the other based on human geography.
