WebDeviation (statistics) In mathematics and statistics, deviation is a measure of difference between the observed value of a variable and some other value, often that variable's mean. The sign of the deviation reports the direction of that difference (the deviation is positive when the observed value exceeds the reference value). WebFeb 3, 2024 · Ans: (a) This mixture shows a positive deviation from Raoult's law. This is because pure ethanol exhibits hydrogen bonding. When it is mixed with acetone, the hydrogen bonding weakens. As a result, the solution shows a positive deviation from Raoult’s law.
