How is an anomaly recognised on a scatter graph?

It sits well away from the line of best fit around which the other points cluster.

What kinds of thing cause genuine anomalies in physical fieldwork?

A local feature interrupting the natural pattern, such as a tributary joining, a weir or bridge, an outcrop of harder rock, or a sea wall or groyne on a beach.

What can cause an anomaly that has nothing to do with geography at all?

Human or equipment error, such as misreading a scale, recording in the wrong units, writing a figure in the wrong column, or a faulty instrument.

Anomalies in fieldwork data

3 things to know
Paper 3 section B

Overview

What an anomaly is and how to spot one on a graph, genuine anomalies in river, coast and human surveys, anomalies caused by error, why they are explained rather than deleted, and how repeat readings help.

Questions from this subtopic

Each one with the model answer underneath.

1
What is an anomaly in a set of fieldwork data?
Model answer
A result that does not fit the pattern or trend shown by the rest of the readings.
2
How is an anomaly recognised on a scatter graph?
Model answer
It sits well away from the line of best fit around which the other points cluster.
3
Give an example of an anomaly a river study might produce.
Model answer
A site where velocity falls or the channel suddenly narrows, against the general increase expected further downstream.
4
What kinds of thing cause genuine anomalies in physical fieldwork?
Model answer
A local feature interrupting the natural pattern, such as a tributary joining, a weir or bridge, an outcrop of harder rock, or a sea wall or groyne on a beach.
5
In a survey of people or of land use, what can produce a real anomaly?
Model answer
A one-off event on the day, such as a market, roadworks, a school emptying or a shop closing down, which changes footfall or land use at that site only.
6
What can cause an anomaly that has nothing to do with geography at all?
Model answer
Human or equipment error, such as misreading a scale, recording in the wrong units, writing a figure in the wrong column, or a faulty instrument.
