County forage-plot moisture probes drop overnight readings. Dropping every incomplete row would erase frost nights. Which missing-value strategy is appropriate?
Select an answer to reveal the explanation.
Short Explanation
Think of overnight moisture gaps. Dropping every incomplete row would erase frost nights. Impute with a justified statistic such as median. Always-drop is the wrong default.
Full Explanation
Impute missing numeric data with a justified statistic. Always dropping rows is worse when those nights are the signal. A string token and Glacier are not numeric imputation.
