What information must you know in order to completely specify the shape of a normal distribution?
the mean and the standard deviation
What describes the shape of a distribution which is approximately normal?
A "bell" shape.
Why Normal distribution is better then other distributions in statistics?
The normal distribution has two parameters, the mean and the standard deviation Once we know these parameters, we know everything we need to know about a particular normal distribution. This is a very nice feature for a distribution to have. Also, the mean, median and mode are all the same in the normal distribution. Also, the normal distribution is important in the central limit theorem. These and many other facts make the normal distribution a nice distribution to have in statistics.
What is the shape of a z-score distribution?
The standard normal distribution or the Gaussian distribution with mean 0 and variance 1.
What is the shape of each distribution in a data set?
The distributions can have any shape that you like.
What is the moment of inertia of the balance wheel about its shaft?
The moment of inertia of the balance wheel about its shaft depends on the shape and distribution of mass in the wheel. To calculate it, you would need to know the mass distribution and shape of the balance wheel.

the mean and the standard deviation
When describing distribution what three things should be mention?
When describing a distribution, it is important to mention its shape (symmetric, skewed, etc.), center (mean, median), and spread (range, standard deviation). These three characteristics provide a comprehensive overview of the distribution's properties.
What shape describes a poisson distribution?
A skewed bell shape.
What describes the shape of a distribution which is approximately normal?
A "bell" shape.
How does the shape of the normal distribution differ from the shapes of the uniform and exponential distributions?
the normal distribution is a bell shape and expeonential is rectangular

Why it is important to find the shape of data distribution before computing descriptive statistics?
to help determine and give insight into the data colleced.
What is the expected shape of the distribution of the sample mean?
The distribution of the sample mean is bell-shaped or is a normal distribution.
What is the shape of a z-score distribution?
The standard normal distribution or the Gaussian distribution with mean 0 and variance 1.
What distribution channel is used by parle g?
The answer choices need to be given to know which is used by parle g. To know this it is important to know which options there are for the answers.
A distribution with a shape that is symmetrical around the mean with a bell shape is described as?
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.
