Significant Figures and Error
When are Significant Figures and Error Covered?
Significant Figures and Error are introduced in
ENGR111 during Class 6.1.
*Explaination
of Class numbering System
Objectives
| Class 6.1: |
Signifant Figures/Error |
|
Learn the differences in: accuracy/percision,
random/systematic error, uncertainty/error |
|
Compute true, fractional and percent
error |
| |
Use proper number of significant
figures to report work |
Class Agenda
| Class 6.1: |
Signifant Figures/Error |
|
Lecture Material on error and
rules for significant figures |
|
A RAT is given early in the class
session |
| |
A paired jigsaw or
group activity to summarize Sig Fig and Error handouts |
|
Team exercise to determine various
types of error |
|
Team exercise to determine significant
figures for algebraic problems |
Why are Significant Figures and Error Important?
Significant Figures determine how
accurate at number is according to the experiment; given data and
results. Sig figs are important because they help to determine the
validity of a number.
Error is the difference between the
reported and actual value and results from a lack of accuracy in
significant figures. Can also be defined as the last digit of a
number. Error is important because it quantifies the inaccuracy
and precision of a certain system.
