What is the shape of this distribution
A skewed bell shape.
the normal distribution is a bell shape and expeonential is rectangular
skewed right.
symmetrical
Rectangular
A skewed bell shape.
A "bell" shape.
the normal distribution is a bell shape and expeonential is rectangular
The distribution of the sample mean is bell-shaped or is a normal distribution.
The standard normal distribution or the Gaussian distribution with mean 0 and variance 1.
skewed right.
symmetrical
The distributions can have any shape that you like.
The distribution described is a normal distribution. It is characterized by a symmetric bell-shaped curve where the mean, median, and mode are all equal and located at the center of the distribution.
Rectangular
It means distribution is flater then [than] a normal distribution and if kurtosis is positive[,] then it means that distribution is sharper then [than] a normal distribution. Normal (bell shape) distribution has zero kurtosis.
In a symmetric binomial distribution, the probabilities of success and failure are equal, resulting in a symmetric shape of the distribution. In a skewed binomial distribution, the probabilities of success and failure are not equal, leading to an asymmetric shape where the distribution is stretched towards one side.
