23.
Noah carries out a T-Level occupational task on good scientific and clinical practice. This is a typical NCFE required-practical style question.
(a) [2 marks]
Independent: the factor being investigated
Dependent: the measured result or quality check
(b) [2 marks]
follow the SOP and keep other variables constant
so the test is fair / only one variable is changed
(c) [2 marks]
not recording the batch/lot number or operator ID
24.
Noah carries out writing or following an SOP for good scientific and clinical practice. This is a typical NCFE required-practical style question.
(a) [2 marks]
Independent: a step in the method
Dependent: whether the acceptance criteria are met
(b) [2 marks]
same calibrated instrument
so the test is fair / only one variable is changed
(c) [2 marks]
skipping a verification check
25.
Noah carries out a COSHH / risk-assessment review for good scientific and clinical practice. This is a typical NCFE required-practical style question.
(a) [2 marks]
Independent: hazard
Dependent: control measure effectiveness
(b) [2 marks]
same PPE and waste route
so the test is fair / only one variable is changed
(c) [2 marks]
using expired reagents or the wrong waste stream
26.
Noah carries out data review in a LIMS or quality log for good scientific and clinical practice. This is a typical NCFE required-practical style question.
(a) [2 marks]
Independent: sample ID
Dependent: result vs specification
(b) [2 marks]
same calculation method
so the test is fair / only one variable is changed
(c) [2 marks]
transcription error between the instrument and the LIMS
