Where the mean is bigger than the median, the distribution is positively skewed. For the logged data the mean and median are 1.24 and 1.10 respectively, indicating that the logged data have a more symmetrical distribution. WebMay 20, 2024 · The distribution is symmetric about x = 0, but the distribution has a minimum at x = 0, not a maximum. So, you know that the point of symmetry is a minimum or maximum, because its derivative has to vanish there (why?), but it could be a local min or local max, instead of a global max. prof herold nürnberg

Web1. It is symmetrical, which means that the values on the left of the mean are the same distance from the mean as the values on the right. A normal distribution has a mean and a standard deviation that are both equal. 2. The distribution has only one peak, making it unimodal, which means that there is only one possible value. 3. WebJan 2, 2024 · The mean is 75, so the center is 75. The standard deviation is 5, so for each line above the mean add 5 and for each line below the mean subtract 5.
