It amazes me that I'm enrolled in a university statistics class, watched a 1.5hr lecture and worked my way through a textbook chapter but was still a little vague on what the Standard Deviation actually was; yet a high school teacher can explain it more effectively. Why am I even paying for a university education?

because in university they don't care about teaching. They are just presenting the information. It is rare to find a real teacher

Are you ever going to cover the normal distribution? I notice it was greyed out on your website so I'm hoping that means you'll cover it soon?

Questions: why do we square? If the answer if to remove the ‘negative’ differences and make them positive, because if we simply find the average of all deviations with keeping negatives negatives and positives positives we will always get 0, then why don’t we take the absolute value?
@NirajMahajan5 жыл бұрын
I guess that’s covered in Mean Deviation. We take absolute deviations in the method of Mean Deviation.

maybe because it's only the denominator of the s.d. equation that needs to be square rooted but formulas are usually "simplified" for elegance's sake so the numerator would be square rooted as well. so for the sake of cancelling out the effect of the square root of the numerator, the values on the numerator now needs to be squared.

It's because later on in discrete mathematics it becomes difficult to manipulate absolute value equations so they square them.

RMS..?? Like in physics with generators?? The root mean square?? What..??

Similar concept. It means you square each entry in a list of terms, average them, and then take the square root. Or in the continuous world, it means you square a function, integrate it, divide by the difference between the bounds of integration, and then take the square root. Two applications in Physics that I know about: 1. Effective voltage of AC waveforms, such as a nominal 240Vac waveform really having a 340V amplitude behind the scenes. 240V = 340V/sqrt(2), such that the 340V AC waveform delivers the same power as a 240V DC source to a resistive load. 2. A representative speed in the Maxwell-Boltzmann speed distribution, that corresponds to the average kinetic energy per gas molecule, as the basis for defining temperature.

Firstly, they can’t arrest her based off of just your word even if your co workers co-sign for you. Secondly, don’t ever state “I know your chief” or “I’m cool with the manager” or any anything that would suggest that you have some sort of leverage or sway with anyone. You definitely do not follow that statement with “ or there’s going to be a problem”, you were the hit and you want Justice I get that. However, we really don’t know if he said anything to her to entice this reaction, it was the wrong reaction but sometimes people can take you there. The video evidence was enough for the officers to see the truth. Let the evidence speak for itself. And lastly, this disorderly conduct nonsense for assault is surprisingly common. How the hell is her practically chasing him and having to be held back and ultimately scratching him in the face just disorderly? Foolishness. Moral of the story if someone calls you a name you need to walk away, not chase them when they walk away and have to be held back by others.
