A student decided not to reweigh his Erlenmeyer flask throughout the calibration lab. After a given trial, he shook leftover water out of his Erlenmeyer flask by wrist action and assumed the mass of his flask was constant. Then, he reused the flask for the next trial and so on. Given this information, how might this affect the student's calibration graph (i.e., explain what the graph might look like)? Is this an example of random or systematic error? Why? Since the buret calibration graph is used to adjust apparent delivered volumes in future labs, how will this student's laziness affect his future data?
The laziness of student can affect calibration in many ways. Such situations leads to errors in the experiment.
The given case could lead to standard deviations that are so high that they endanger the calibration.
Different operators may generate measurements with biases that vary in sign and magnitude.
It can lead to incorrect plotting of graph.
The mistake done by student is an example of systematicerror.
Systematic Error:Incorrectly calibrated or improperly used measuring equipment is typically the root cause of systematicerror. However, errors can enter your experiment from different means.
As student doesn't reweigh his Erlenmeyerflask throughout the calibration lab so this comes under improper handling of equipment. therefore, it is systematic error.
Student's laziness will affect his data which he will use as reference in future for further experiments.
There will be huge error in calibrationgraph which will lead to incorrect adjustments of volumes in labs.
