Shape of the normal curve
Webb2 jan. 2024 · There is a special symmetric shaped distribution called the normal distribution. It is high in the middle and then goes down quickly and equally on both ends. It looks like a bell, so sometimes it is called a bell curve. One property of the normal distribution is that it is symmetric about the mean. WebbThat is the normal distribution has a skew of zero. A skewed distribution has a tail at either of the sides. A tail refers to the tapering off on one side of the graph. If the curve has a tail in the positive direction, it is said to have positive skew and the long tail is in the negative direction, the curve is said to have a negative skew.
