WebA symmetric distribution is a data visualization that appears virtually identical on both sides. It’s worth noting that the data doesn’t have to be identical on both sides to be termed symmetric; it only has to be close. Consider a mirror positioned in the midst of data distribution. Both sides should be almost exact replicas of one another. WebOct 1, 2024 · The T-statistic, also called the T-score, is given by: t = (x–μ) ( S √n) t = ( x – μ) ( S n) Where: x is the sample mean, μ is the population mean, S is the sample standard deviation, n is the sample size.
