Measurement error

Systematic error

Random error

What error varies randomly between measurements?

Systematic error

Bias

Random error

If measurements are tightly grouped but far from the true value, what is high and what is low?

Low precision, high accuracy

Low precision, low accuracy

High precision, low accuracy

Which of the following improves precision in measurements?

Increasing sample bias

Using fewer trials

Repeating measurements and averaging

A ruler reads consistently 0.5 cm longer than true length. What error is this?

Measurement error

Random error

Systematic error

Which metric is best described by narrow spread of values?

High bias

To improve both accuracy and precision, you should:

Calibrate instrument and repeat measurements

Ignore outliers

Use a harsher instrument

Which combination is ideal: high accuracy or high precision?

High precision only

High accuracy only

Both high accuracy and high precision
