- In this video I'll go over the categories for classifying data such as nominal, ordinal, interval, and ratio. To classify these remember to ask questions like, "can the data be ordered?" For more videos please visit www.mysecretmat...
Today i've watched 20+ videos to understand the issue but all the videos are vague.. I could have stop watching videos on this topic but finally i've got my best video❤️
Thank you sooo Much dear
this the best explanation with examples that relate to real life. Really helped me get a grasp beyond just definitions.
I seriously wish I found you earlier! I have my Statistics midterm tonight. and my professor isn't really demonstrative.
Brilliant, struggling with interval scale and ratio scale, this is good. although I got the shoe size question wrong. My bad... Thank you so much for this vid.
Great job teacher!
Amazing Explanation. I have an outstanding Professor and wish I coul pause the class sometimes. Subscribed.
Best video on this topic so far!!
Its great and the way you use examples are awesome
This is very helpful, thank you for you life!
thank u so much , i really had hard times figuring out , what level of measurement to use , and u helped a lot , thanks again
I really can't understand the examples in our book and watching the examples in your videos enlighten me. Thank You. God Bless.
Thank you for your explanation
The zero shoe length is a bit confusing. I was thinking interval and not ratio. I mean n/a or null (no shoe) is not equal to zero (there's a shoe but it's just 0 length). I mean zero is a value right?
Zero is definitely a value, but you have to ask if that zero corresponds to "nothing" of what you are measuring. Let's say my wife buys a size "0" dress. Does that mean that she has "no" waist? In this case the zero is not meaningful to what you are measuring.
Classify the following quantitative data according to type and level of measurement.
1.Days in a year
2.Number of students enrolled in statistics
3.Number of body hais
4.Months
5.Number of stars in the galaxy.
Can you explain me sir about that question that I give.
Im looking forward for your response Sir.
Thanks this made a lot of sense
The vid helped so much...thanks
Thank you so much! This was really helpful.
how would you classify mortality or mortality rate?
very informative.
this video is so helpfu ! Thank you!l
Keep it up!
I'm unable to identify interval and ratio..
Year, Shoe Length, Temperature examples are unclear. Please help.
I wrote a bit more about this on my website if you want to check them out. I also included a few examples to help you know the difference between the two. Basically the difference is having a natural place for zero. :^D

@@MySecretMathTutor I read it and understood, still the examples are a bit unclear.
I don't understand ratio and interval at all. I am quite lost with those two
The main difference is that the ratio level has a natural "zero." That means zero stands for nothing of that thing.
A good example of something that is not at the ratio level is the size of a women's dress. There are size 0 dresses, but 0 does not correspond to "no size," or "no measurement." (According to google size 0 has a waist of about 24" )
Thank you!! ^_^
I was with you until you got to the Years and 0 having no value. Completely lost you there.
I got the answer. I was puzzled too at first. Ask yourself? Does the value of zero makes sense? If yes then ratio; if not then interval. Value of 0 for year does not make sense, so interval.
