Variable Frequency Drive (VFD)

A variable-frequency drive (VFD, or adjustable-frequency drives, adjustable-speed drives, variable-speed drives, AC drives, micro drives, inverter drives, or drives) is a type of AC motor drive (system incorporating a motor) that controls speed and torque by varying the frequency of the input electricity. Depending on its topology, it controls the associated voltage or current variation.

OH MY GOSH THAT Variable Frequency Drive (VFD) SOUNDS AMAZING THAT PWM TOP NOTCH MMM CHEFS KISS

Late variables

When you commit to do something fun with your friends only to be told by your partner you have to change your plans.

Ken: are you still coming on the holiday we planned?
Dan: sorry, I’m experiencing late variables.

Sampling Variability

The fact that different random samples of the same size from the same population produce different estimates.

As we study sampling variability, which do you suspect varies less: averages or individual values?

One consistent variable

You don't know how many consistent variables there are and if I had video evidence of a consistent variable that wasn't me you would hack the product ordering system of my place of employment and then all of the people I spoke about online would get fired or transferred within a month.

Hym "You're presupposing that there's only one consistent variable. You can't possibly believe there are not externally imposed circumstances. 'BuT yOu CaN't Do AnYtHiNg AbOuT tHoSe BeCaUsE iT cOuLd ReQuIrE mE tO dO sOmEtHiNg I dOn'T wAnT tO' Fucking garbage."

isolate the variable

the act of focusing on an appealing portion of a person's body with a general disregard for the undesirable regions

Steve: Could you isolate the variable on that?
John: You know it. She's huge, but those are some mighty fine sweater cows.

Bill: You see that?!?!
James: You serious? She's hideous.
Bill: C'mon you gotta isolate the variable.
James: You right. She needs to turn back around though.

Confounding Variable

Variables that occur when the two explanatory variables , x and z, have a collective causation effect on y. The difference between the two cannot be distinguished because there is not enough evidence to determine the validity of a statistical relationship.

Weight gain is greatly influenced by activity level, but age, the confounding variable, also plays an influential role on weight gain.
