Define A in the ALCOA Principles
A - Attributable
Attributable:
Data should clearly demonstrate Who observed and recorded it.

When a k‑factor of 2 is used in a calibration certificate, what does it mean
A k‑factor of 2 means the measurement uncertainty has been expanded by a factor of 2, which typically corresponds to about 95% confidence that the true value lies within the stated uncertainty range.
100
What is measurement uncertainty?
Measurement uncertainty is the estimated range around a measured value that expresses how much the measurement might vary from the true value.

Define L in the ALCOA Principles
L - Legible
Legible:
Data should be readable, easy to understand, recorded permanently and original entries should be preserved.

Definition of Standard deviation (in layman's terms)
(Bonus points: Write the formula)
The Average distance to the mean

Define C in the ALCOA Principles
C - Contemporaneous
Contemporaneous:
Data should be recorded as it was observed and the time it was executed.
300
Definition of Tolerance Interval (in layman's terms)
(Bonus points: Write the formula)
A two-sided tolerance interval consists of two limits between which a given proportion of the population falls with a given confidence level
L = x̅ - s *K
U = x̅ + s *K

Accelerated aging for medical devices is based on what theory?
Accelerated aging is based on the Arrhenius equation, which states that chemical degradation reactions speed up as temperature increases.

Define O in the ALCOA Principles
O - Original
Original:
Source data should be accessible and preserved in its original form.

What is the difference between a Z and T distribution?
- Z‑distribution is used when the population standard deviation (σ) is known.
- T‑distribution is used when σ is unknown and must be estimated from a sample.
400
Why is it important to take account for Measurement Uncertainty?
To avoid:
A Type II error (false negative) happens when you conclude there is no issue when in fact there is one.

Define A (the last A) in the ALCOA Principles
A - Accurate
Accurate:
Data is error-free complete, truthful and that it reflect the observation made. Editing data without logging means its accuracy it lost.
500
Definition of Confidence interval (in layman's terms)
(Bonus points: Write the formula)
95 % Confidence interval of the mean:
If you take 100 different samples from a population and calculate the 95% confidence interval for each sample, then statistically 95 % of the confidence intervals will contain the true mean.

Describe the difference between precision and accuracy.
(All Teams - use the whiteboard you have 2 min)
Accuracy is the proximity of measurement results to the accepted/true value.
Precision is how close the measurements are to each other.
