Wow! This was great! Thank you so much for the information! This really was simple to follow and easy to understand! The wage example really sealed everything nicely! I hope to see more videos from you. -Intro to Stats Student in Pittsburgh
I finally get it!!! I think my teacher had the first day of school jitters and couldn't get the class to understand the difference between the 2. Thank you!
This is a great video! I have been confused but encountered this concept a bunch of times. This video really helps me understand the vagueness that bugs me all this time!
I'm not entirely certain what it would mean, but my guess would be they're talking about how with interval data zeros aren't really a problem - meaning you can subtract zero just fine. But with ratio data you do have to be careful about dividing by zero. If your salary goes from $0/hour to $10/hour would you say that you've increased by $10 or that you've increased by 10/0.... well the division side just doesn't make sense. So if you have a lot of zeros (or if the value of zero is important to the dataset) then ratio data may not be the best idea.
Thank you so much sir for such fast reply sir sir i am talking about Here’s the problem with interval scales: they don’t have a “true zero.” For example, there is no such thing as “no temperature,” at least not with celsius. In the case of interval scales, zero doesn’t mean the absence of value, but is actually another number used on the scale, like 0 degrees celsius. Negative numbers also have meaning. Without a true zero, it is impossible to compute ratios. With interval data, we can add and subtract, but cannot multiply or divide. for reference please find below link www.mymarketresearchmethods.com/types-of-data-nominal-ordinal-interval-ratio/ Regards
The important thing is in how you interpret your results. Either way you'll get a model for predicting (and in most realistic cases either model will get you decently good predictions) but when you interpret it you'll get nonsense with the wrong model. For example, if the temperature is 20 degrees, and you predict it's going to get "twice as warm" what does that mean? Twice as warm doesn't make sense because temperature is interval data, not ratio. You would predict it will get "20 degrees warmer". Now that makes sense. Trying to determine whether the error structure of temperature is ratio or interval isn't nearly as important as realizing that a ratio interpretation is garbage, so you have to treat it as interval.
The term "negative marking" is pretty broad - usually it's about how a teacher takes away points if you get a question wrong. If they're taking away a specific number of points that's interval. If the teacher takes away a percentage of the total points, then it's ratio.
Scott Crawford can u answer my questions about nominal, ratio , interval and ordinal.. 1. Intelligence quotient of employees 2. Pages in PLDT telephone book. 3. Beauty contest winners 4. The number of passengers from chicago to san diego.. 5. Social Security System (SSS) Number
Excellent explanation! I started a stats course and the concept was poorly explained by both my textbook and my professor. Thank you!
Great, simple explanation of a concept that was confusing me till now! Well done!
Chuck
WOW, SUCH A GREAT EXPLANATION! NOW I UNDERSTAND THIS SUBJECT. THANK YOU
Love this video! and love the energy!! have known of interval vs ratio data for years but never had this point of view.
Wow! This was great! Thank you so much for the information! This really was simple to follow and easy to understand! The wage example really sealed everything nicely!

This is probably the best explanation of anything I've seen in years.
I suffered a lot to understand this before watching this. You save me sir, Thank you
I finally get it!!! I think my teacher had the first day of school jitters and couldn't get the class to understand the difference between the 2. Thank you!
I love this video, especially the part around minute 5. Thanks for this educating & entertaining video!
My professor explained this so badly but you explained it so well. Thank you!
I have been searching for a legit explanation for this. Thank u.
best explanation i have ever seen on this topic thanks 🙏
This is a great video! I have been confused but encountered this concept a bunch of times. This video really helps me understand the vagueness that bugs me all this time!
wow man thank you so much , your explanation is greater than any professor , thanks
Explained a lot of my doubts sir , thank you very much !
4:41 Thank you ! you are a great
Ha! I liked your explanations - thank you! Very entertaining and informative.
very nice explanation...thank you so much sir
"We've now lost the losers..." LOL!
Hahaha that was hilarious. I liked this video just because of the jokes
happy that i found this video. thank you!
Thank you for sharing I appreciate the video which was very helpful #IntroStatsBusStudent
I didn't turn the video off... I didn't want to offend you y.y
Amazing kind sir!
7 years later i find this amazing explanation, thank you so much for making the concept clear for me
hahahha the way he got angry. cute!
thanks so much for teaching in a fun way!
i laughed hard when you got mad XD
God bless you! Thank you!
You're amazing. Thank you.
sir it was really excellent
i have only one doubt some time they say zero doesnt have value
and in ratio zero has value what does that mean

@@sdcstats what measurements scale is a metre rule?
INTERVAL
ORDINAL
RATIO
NOMINAL ASAP
YOU ARE AWESOME!
LOL! Loved this! thank u!
thank you so much, so helpful :)
Great explanation!
Excellent 👍
Awesome job! Thank you. New to Stats.
Thank you Sir
This is fun (4:50 lol) and informative 😂💗
thank you sir!
Thank you!! So helpful
Fucking Legend🛐🛐
So how would we go wrong if we used interval analysis for a ratio data or vice versa ? Please could you provide more references?

Nice thank you sir
Thanks for making me understand
You are amazing..
Thank you ! 👏🏽

Which measurement scale is a metre rule?
Interval
Ratio
Nominal
Ordinal
I would say interval. It has increments that increase at a steady continuous rate.
thank you so much !!
thank you very interesting!
youre hilarious!!!!!!!!!!!!
Thank you so much! This is really helpful!
It's not at all times two datas will be given. These examples should be more diverse

aww!!! 😂😂

i finally understood it
haha this is great!
lol great video

Negative marking is ratio scale Or interval?
The term "negative marking" is pretty broad - usually it's about how a teacher takes away points if you get a question wrong. If they're taking away a specific number of points that's interval. If the teacher takes away a percentage of the total points, then it's ratio.
thanks
is GPA considered a interval?
I would consider it interval. If my GPA goes from 3.2 to 3.6 I think I've increased my GPA by .4, not that I've gone up by 12% (or whatever value)
@@sdcstats thank you very much ❤️.
ha ha ha, a stats prof forgot 3 numbers he spoke...
That nose though XD
+Sam Miguez no chill..
That's where I store my ego
+Scott Crawford don't worry about him, keep up the good work!
Scott Crawford can u answer my questions about nominal, ratio , interval and ordinal..

i also have a big nose, as a women, what now? are we ugly thats why?
