|
|
|
The mean, median, and the mode are equal.
|
|
|
The mean of the distribution can be negative, zero, or positive.
|
|
|
The distribution is symmetrical.
|
|
|
The standard deviation must be 1.
|
Detailed explanation-1: -The correct answer to the given question is option The value of the mean is always greater than the value of the standard deviation.
Detailed explanation-2: -Characteristics of Normal Distribution Here, we see the four characteristics of a normal distribution. Normal distributions are symmetric, unimodal, and asymptotic, and the mean, median, and mode are all equal.
Detailed explanation-3: -A normal distribution has some interesting properties: it has a bell shape, the mean and median are equal, and 68% of the data falls within 1 standard deviation.
Detailed explanation-4: -The standard normal distribution is a special case of the normal distribution. For the standard normal distribution, the value of the mean is equal to zero (=0), and the value of the standard deviation is equal to 1 (=1). The random variable that possesses the standard normal distribution is denoted by z.
