The correct answer is A. Mean.
A Gaussian distribution, also known as a normal distribution, is a probability distribution that is symmetric about its mean. This means that the mean, median, and mode are all equal. The bell-shaped curve of a Gaussian distribution is often used to represent the distribution of data in a population.
The variance of a distribution is a measure of how spread out the data are. A low variance indicates that the data are clustered close to the mean, while a high variance indicates that the data are spread out over a wider range of values.
A discrete distribution is a probability distribution that can only take on a finite number of values. A random distribution is a probability distribution that does not have a specific shape.
In conclusion, the correct answer to the question “Gaussian distribution when plotted, gives a bell shaped curve which is symmetric about the . . . . . . . . of the feature values” is A. Mean.
