Examples Of Normal Distributions. The number of people taller and shorter than the average height people is almost equal and a very small number of. It has zero skew and a kurtosis of 3. We can convert any normal distribution into a standard normal distribution. For example height and intelligence are approximately normally distributed.
Its often called a bell curve or a Gaussian. In many practical cases the methods developed using normal theory work quite well even when the distribution is not normal. For example height and intelligence are approximately normally distributed. It has zero skew and a kurtosis of 3. Because normally distributed variables are so common many statistical tests are designed for normally distributed populations. A cool thing related to them though is the Central Limit Theorem.
The mean is the peak of curve it is symmetrical around its mean The standard deviation determines width of curve the larger the SD the wider the curve Normal distribution tends towards infinity ie.
Its often called a bell curve or a Gaussian. All kinds of variables in natural and social sciences are normally or approximately normally distributed. While all 3 of the above distributions may appear different they are in fact all identical in one regard. Another is the distribution of errors in measurements. Where σ ensures standard deviation is 1 and µ ensures mean is 0. For example height and intelligence are approximately normally distributed.
