Here are the most common mathematical symbols:Here's the formula for calculating a z-score: z = data point − mean standard deviation. Here's the same formula written with symbols: z = x − μ σ. Here are some important facts about z-scores: A positive z-score says the data point is above average. A negative z-score …The standard deviation is 0.15m, so: 0.45m / 0.15m = 3 standard deviations. So to convert a value to a Standard Score ("z-score"): first subtract the mean, then divide by the Standard Deviation. And doing that is called "Standardizing": We can take any Normal Distribution and convert it to The Standard Normal Distribution.
