I am so confused. How do you tell the significance? Is it by seeing if they are in close range or maybe far apart or what

Interesting video. How can I codify X1 if each point has a logarithmic increment? For example, A = 0, 1, 10, 100. x1 ~ (A - 100)/Log(10), is it correct? Thanks

Hello, when x = 1 there is a difference of 5°C or 5 minutes which means 1 = 5 so in order to calculate how much is 1,414 you just have to do 1,414 * 5 and you find 7,07. I hope this is clear.

hi, I'm working on laser-assisted turning and currently experimenting with five parameters: depth of cut, feed rate, spindle speed, laser power, and laser angle (the distance between the laser spot and cutting edge). Initially, I opted for a face-centered central composite design. However, I've noticed that when the laser power is set to 0 (indicating the laser is off), the laser angle becomes irrelevant. I'm uncertain about the appropriate experimental design in this situation. Could you please suggest a method or name for this scenario, considering the disregard for laser angle when laser power is zero? Thank you for your insights!

Hi Amir, you can send me an email using the contact on the channel details, so we can discuss your experiment.

What if your grouping variable is not interval?? How could you do this for nominal categories such as an experiment (where this would obviously be the most useful)? Specifically, the step in which you identify between group differences with Tukey's test is extremely cumbersome if the variables do not have a linear relationship.
@RosaneRech8 ай бұрын
The variables don't need to have a linear relationship. You can use the same procedure for categorical variables.
