PHYSICS
Use graphical analysis to determine
simple non-linear physical relationships
Graph data.
performance criteria
1.1
The independent variable is plotted on the horizontal axis unless otherwise
stated.
1.2
Axes are labelled with the quantity and unit of the selected variable.
1.3
Points are plotted clearly consistent with the provided data.
1.4
The curve or line of best fit is drawn.
element 2
Determine simple non-linear physical relationships.
performance criteria
2.1
A relationship is predicted consistent with graphed data.
2.2
Predicted relationships are verified by graphing data processed according to the
predicted relationship.
2.3
The determined value of the gradient of a linear graph is consistent with the line
of best fit.
2.4
A mathematical statement of the identified relationship is consistent with a linear
graph of the processed data.
2.5
A linear graph is used to determine a value for an unknown variable.

Please Note
Providers must be accredited by the Qualifications Authority or a delegated interinstitutional body before they can register credits from assessment against unit standards
or deliver courses of study leading to that assessment.
Industry Training Organisations must be accredited by the Qualifications Authority before
they can register credits from assessment against unit standards.
Accredited providers and Industry Training Organisations assessing against unit standards
must engage with the moderation system that applies to those standards.
Accreditation requirements and an outline of the moderation system that applies to this
standard are outlined in the Accreditation and Moderation Action Plan (AMAP). The
AMAP also includes useful information about special requirements for providers wishing to
develop education and training programmes, such as minimum qualifications for tutors and
assessors, and special resource requirements.
This unit standard is covered by AMAP 0226 which can be accessed at
