Variance is the state or degree of being different or inconsistent.
Statistical variance measures how far data points spread from their average.
Legal variance is official permission to deviate from regulations: The homeowner sought a variance to build closer to the property line.
At variance means in conflict or disagreement: His actions were at variance with his words.
