got suckered into this one. Even though I had the lowest variation it had a higher deviation from the mean from III. “The more data closer to the mean the lower deviation” The scores were more average in III then in I. To think of it as heights in a group or normal score distributions: III is the most normal while I is less normal and II is the least normal of expected distributions or deviation.
