Topic #: 1

Show Suggested Answer

Suggested Answer: B

The Gaussian distribution, also known as the normal distribution, is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean. In graph form, the Gaussian distribution will appear as a bell curve, which is the case with option A. It is characterized by its bell-shaped curve and is defined by the mean () and the standard deviation (). It is a common assumption for the distribution of independent, randomly generated variables.

Gauss would be proud to see this question! Option B is the textbook example of a Gaussian Distribution, no need to overthink it.

Yes, Gaussian Distribution is all about that bell curve shape, so option B fits perfectly.

Hold up, is this a trick question? I'm pretty sure option B is the Gaussian Distribution, but you know what they say, 'Gaussians come in all shapes and sizes!'
