addiscombe tram stop
2.why :
proximity->close to our academy
accesability-> walking distance, safe
Time-fieldwork completed in a day
Contrast- three sites provided enough contrast
physical fieldwork
investigating downstream changes in the river Beck

why:
Proximity -> close to our academy
Accessibility -> walking distance, safe , residential , public transport
Time: fieldwork completed in a day
contrast: three sites provided enough contrast
bar graphs strengths
Summarises a large set of data
Easy to interpret and construct
Shows trends clearly
types of bar charts
DIVIDED:
The bars are subdivided to show the information with all bars totalling 100%
The main use of a divided bar chart is to compare numeric values between levels of a variable such as time
population pyramids
A type of histogram
Used to show the age-sex of a population
Can be used to show the structure of an area/country
Patterns are easy to identify
bar graphs limitations
Requires additional information
Does not show causes, effects or patterns
Can only be used with discrete data
line graph strengths
Shows trends and patterns clearly
Quicker and easier to construct than a bar graph
Easy to interpret
Requires little written explanation
line graphs limitation
Does not show causes or effects
Can be misleading if the scales on the axis are altered
If there are multiple lines on a graph it can be confusing
pie charts strengths
Clearly shows the proportion of the whole
Easy to compare different components
Easy to label
Information can be highlighted by separating segments
pie charts limitation
Do not show changes over time
Difficult to understand without clear labelling
Hard to compare two sets of data
Can only be used for a small number of categories otherwise lots of segments become confusing
rose diagrams
Use multidirectional axes to plot data with bars
Compass points are used for the axis direction
Can be used for data such as wind direction, noise or light levels
triangular graphs
Have axes on three sides all of which go from 0-100
Used to display data which can be divided into three
The data must be in percentages
Can be used to plot data such as soil content, employment in economic activities
scatter graphs strengths
Clearly shows data correlation
Shows the spread of data
Makes it easy to identify anomalies and outliers
scatter graph limitations
Data points cannot be labelled
Too many data points can make it difficult to read
Can only show the relationship between two sets of data
choropleth limitation
Makes it seem as if there is an abrupt change in the boundary
Distinguishing between shades can be difficult
Variations within the value set are not visible
choropleth strengths
The clear visual impression of the changes over space
Shows a large amount of data
Groupings are flexible
proportional symbols map strengths
Illustrates the differences between many places
Easy to read
Data is specific to particular locations
proportional symbols map
limitations
Not easy to calculate the actual value
Time-consuming to construct
Positioning on a map may be difficult, particularly with larger symbols
photographs strengths
An accurate record of the time
Can represent things more clearly than numerical data
Can be used to show data-collection techniques
Can be used next to historical photographs to show changes over time
Helps recall key features
