Fieldwork: Presenting river data
I can present river data to show correlations in the data.
Lesson details
Key learning points
- A channel profile is a way of graphically representing the shape of a river channel.
- It may be possible to see correlations between river characteristics by drawing a scattergraph of the data.
- A line of best fit helps geographers understand the nature of any correlation.
Keywords
(channel) profile - a graph that shows the shape of a river channel as if it were sliced from bank to bank
Line of best fit - a straight line drawn over the top of the data in a scattergraph to show any correlation
Correlation - the relationship between opposing geographical variables
Common misconception
Points in a channel profile should be joined using a ruler.
Points in a channel profile should be drawn with a slight curve to more accurately represent the shape of the river channel.
To generate more than six data plots for a scattergraph, a set of class data can be produced which collates data together.
