Omg I'm literally doing my happy dance! This past summer I spent close to $700 on tutoring for chem. I can't afford tutoring again this semester so I was freaking out about stats, but your vids are saving me. I cannot believe this is free. FREE?!! Thanks!!
@nitrousflash59 sorry nevermind, I just realized that for ratio level data, zero means absent or nothing is there. As with interval zero can still mean something is there like temperature or something else.
Thank you so much your videos are really helping, but why we can't have a natural zero for temperature. There is 0 degrees Celcius right, the freezing point of water.
Natural zero means that what we are measuring is absent when its value is 0. For example, "zero students in a class" means that there are no students in that class. However, 0 degrees Celsius does not mean the absence of temperature.
@statslectures you said that its not possible to have a measurement of 0 degrees farenheit. But since zero degrees is possible, doesnt that make it ratio level data?
0 Farenheit is possible, but I think he meant that 0 Farenheit is not a ratio variable because 0 F does not imply 'absolutely no temperature'. On the other hand Kelvin is a ratio variable since 0 K does means, theoretically, absolutely no temperature. Thus Farenheit/celsius are interval variables. So we can say that the Farenheit scale does not have a true or meaningful zero.
Hi, many thanks for the lecture series, going through all 66 of them and it is tremendously helpful! just a quick question is time measurement considered interval data or am i confusing it due to thinking time has intervals?

there can be a 0 kelvin....Kelvin just can't be negative
0 Kelvin is known as absolute zero but hasn't been able to be reached yet but it does exist

thanks for uploading this =)
Actually isnt it possible to have zero degrees, it'd just be really cold.
thank you it was really clear. :)
Thank you :)

Sir or Ma'am,
Could you please change the category type to educational please? It would be greatly appreciated :)
Nice
