Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.

Observation Checklist

Tasks to be observed according to workplace/college/TAFE policy and procedures, relevant legislation and Codes of Practice Yes No Comments/feedback
Specify an equation for the measurement 
List uncertainty components that are associated with each input in the equation 
Calculate the standard deviations and standard deviation of the mean from the repeated measurement results 
Use calibration reports, manufacturer’s specifications, quality control and validation data, and experimental data to collect other available information on the uncertainty components 
Assign degrees of freedom to each uncertainty component 
Allocate an appropriate distribution for each uncertainty component 
Calculate the standard uncertainties 
Calculate the sensitivity coefficient for each uncertainty component and multiply each standard uncertainty by its sensitivity coefficient and ensure they are all expressed in the unit of the output 
Calculate a combined standard uncertainty 
Determine an appropriate coverage factor based on the estimated effective degrees of freedom 
Calculate the expanded uncertainty 
Report the measurement result and uncertainty to an appropriate number of significant figures 
Report the confidence level and coverage factor 
Determine the appropriateness of the size of the expanded uncertainty relative to the tolerance or required accuracy of the test 
Determine the fitness for purpose of the expanded uncertainty relative to the use of the measurement result
