An aerospace engineering firm is testing two different docking algorithms, Algorithm P P\,P and Algorithm QQQ, for an autonomous spacecraft. They measure the docking alignment error (in millimetres) over 200 simulation runs.
The alignment errors for Algorithm P P\,P are highly erratic and widely dispersed over a broad range.
The alignment errors for Algorithm Q Q\,Q are highly consistent and tightly clustered near the mean.
State how the standard deviation of alignment errors for Algorithm P P\,P would differ from that of Algorithm QQQ.
