What documents are used to form risk assessments?
Safety data sheet (SDS)
Difference between qualitative and quantitative?
Qualitative - descriptive, focuses on qualities and characteristics
Quantitative - numerical information that can be counted/measured
What is accuracy?
When the data is close to the true value
What is precision?
When the data is close together
What is repeatability?
The ability for the same person to produce the same results under the same conditions
What is reproducibility?
The ability for a different person in different conditions to produce the same result
What makes an experiment valid?
If it accurately measures the aim and produces reliable results
What are systematic errors? What do they effect?
Faulty equipment, improper calibration, or flawed experimental designs
Effects accuracy of all measurements
What is random errors? What do they effect?
Random errors in measurements are caused by unpredictable and unknown changes in the experiment, often due to limitations in instruments or environmental factors
Affects one result, accuracy of average result. Minimized with multiple trials
