In this session we look at a simple pattern created by putting matches together to form a connected path of triangles.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 says the data point is below average. A z-score close to 0. The z-score can be calculated by subtracting the population mean from the raw score, or data point in question (a test score, height, age, etc.), then dividing the difference by the population standard deviation: where x is the raw score, μ is the population mean, and σ is the population standard deviation.
