So what I did is I evaluated the cumulative distribution function at 1, which would be right there. So we're calculating for this example, the way it's drawn right here, the normal distribution function. These distributions are called right — or left—skewed according to the direction of the tail.

It'd be given by this area. You know the mean. If you take something to an exponent, and then take that to an exponent, you can just multiply these exponents.

If you're right-tailed, you're probably right skewed. Modern portfolio theory commonly assumes that the returns of a diversified asset portfolio follow a normal distribution. You might just want to off of the tail. If you're left-tailed, you're probably left skewed. Even if the normal distribution describes well the majority of dick-sizes in the middle, we see too many big dicks, and not just on Wall Street.

Every time I move this, I have to get rid of the Pen tool. You have to say between a range. Sure, the human vagina possesses a remarkable elasticity and during childbirth stretches to an astonishing degree--but not without extreme pain and a vastly different set of circumstances from those obtaining during intercourse.

Or you could just take the height of this line right here, and multiply it by the base, and you'll get the area of this rectangle, which might be a pretty good approximation for the area under the curve, right, because you'll have a little bit extra over here, but you're going to miss a little bit over there.

It's going to be 0. So if the mean goes from 0 to-- let's say it goes to 5. The probability is given by the area under that curve, right. And I encourage you to email me if you see some insight on why this exists, and all of that.

What's the probability that I land between-- let's see. And that's actually what I do in the other video, just to approximate the area under the curve, and give you a good sense that the normal distribution is what the binomial distribution becomes, essentially, if you have many, many, many, many trials.

And just so you know how I calculated everything-- and I really want you to play with this, and play with the formula.

And that could be described by a normal distribution, because it says, anything can happen, although it could be very, very, very improbable.

You have to give it your x value. Our mean is negative right now, right?.

All 3 curves (red, blue, green) are normal distributions [Edit and solution to my question (thanks Hyperplane): Turns out they are not the curves of a normal distribution. I learned "Gaussian" does not necessarily mean a probability density function].

normal (bell-shaped) distribution The normal distribution has a histogram that is bell-shaped. This shape often comes up in cases where the variable arises as a result of the sum or average of a number of smaller components of a similar nature.

Table of Standard Normal Probabilities for Negative Z-scores Author: CNSI Created Date: 8/8/ PM. Watch video · The normal distribution is arguably the most important concept in statistics.

Everything we do, or almost everything we do in inferential statistics, which is essentially making inferences based on data points, is to some degree based on the normal distribution.

The Voigt distribution, or Voigt profile, is the convolution of a normal distribution and a Cauchy distribution. It is found in spectroscopy when spectral line profiles are broadened by a mixture of Lorentzian and Doppler broadening mechanisms.
