WebA 1 in a z-score means 1 standard deviation, not 1 unit. So if the standard deviation of the data set is 1.69, a z-score of 1 would mean that the data point is 1.69 units above the mean. In Sal's example, the z-score of the data point is -0.59, meaning the point is approximately 0.59 standard deviations, or 1 unit, below the mean, which we can ... Webscores scores by multiplying the given Z-score by 10 (the standard deviation of the distribution of T-scores), and adding 50 (the mean of the distribution of T-scores) to this product. For example, a Z-score of –1 equals a Deviation IQ of 40 [50 + 10(-1) = 40]. The formula for transforming Z-score into a T-score is a follows: 50 + 10(z)
