- The kind of graph and analysis we can do with specific data is related to the type of data it is. In this video we explain the different levels of data, with examples.
0:00 Intro
1:07 Nominal
1:46 Ordinal
2:43 Interval/Ratio (scale. quantitative)
3:23 Graphical representation
4:05 Example - Helen's survey about chocolate
We recommend you try the examples in the companion video, Types of data - practice identifying, Shopping Mall example

It's been almost 11 years but this video is still helpful for understanding the different types of data. Thanks a lot, Dr. Nic 🤩
Most welcome
This is so much easier to understand the first time through vs the complete waste of professors I am currently dealing with... tenure= forgot that the job is called teaching
czcams.com/video/Zq2L4o7vSi8/video.html
The idea of a tenure still seems weird to me as a European
@jowl88 @psipsychologytutor @alwilber79 You are all most welcome. It took me quite a while to think out how to make this one. Please tell your friends, classmates and instructors. You might find some of our other videos useful too.
The difference isn't usually relevant in statistics, so I didn't confuse things by adding that level. Ratio data has a meaningful zero value, and ratios of numbers make sense. For example temperature is interval data as the difference between 30 degrees and 40 degrees is the same as the difference between 40 degrees and 50 degrees. However it is not meaningful to say that 40 degrees is twice as hot as 20 degrees. So temperature is not ratio data. Length in mm, is ratio data. 20mm is twice 10mm.
Statistics Learning Centre beautiful girl with fresh mind.
Thanks for this information!
not only themperature, but the rating is iterval, it havn't the absolute zero
Thank you so much this is so much clearer and more concise than my lecturers explain things and I pay £9000 a year for that
Sorry! I started on the chocolate theme almost by accident in the first video, absolute and relative references in Excel. (On the UCMSCI channel) Then it just sort-of grew from there. My students complain that the videos make them hungry. Maybe I should make some more based on carrots or tomatoes.
He..he..., i am fasting while watching and yea i am little hungry, anyway thanks for the video, it is very helpfull
Thank you Dr. Nic!!! Your video has and will help me tremendously in my statistic class. Before finding your video I wasn't sure that I would be able to pass this class successfully. Now I am confident that I can and will ace this class!
You are my hero for making this channel!
Thown in the deep in doing Stats and Research at Uni in first Unit as a Older Student and competing against year 12 students who learnt this and we NEVER did in high school 23 year years ago
You have helped me soooo much with the manner in which you simply explain things and I don't feel so overwhelmed having caught up!
Angel!! xxx
Thank you - your comment made my day.
This video is very helpful for anyone starting to do quantitative research.
D
Or Intro To Stats in Psychology
Agreed!
am humbled by this video
actually it has shown
the simpler methods of data presentation
I just wanted to thank you for all the videos. They're all very informative and easy to grasp.
11 years +, but still legit.
given clear examples and nice visual.
kudos and thank you doc.
Much appreciated!
Oh wow estoy impresionada porque este video me salvo una exposición grupal!!.Santo cielo eres grande muchacho me llenas de felicidad con tus videos que aunque pasaron varios años aun sigue ayudando a gente como yo!!
Fantastic! Really does help, even a university student like me! It's quite simplified and the little animations are quite entertaining. Thank you very much for your efforts x
Thanks! I passed the board because of this video.
Thank you so much, Dr.Nick, this has been so helpful.
You're very welcome!
I teach a band of 180 students every year on research methodology and after i explain the concepts to them i play your video to the class . I can see the light in their faces when they see the video . They do walk up to me and tell me it helped the concepts to solidify faster in their brains. Most of them might end up subscribing it to you . As i make it a point to credit you in the end. Mostly they love your pictures that you choose, so keep it up :) - From India
Thanks! it is great to hear we are helping people learn.
I'm sorry you feel like that. There are also quizzes that help you to learn the content. We think this is an important addition to help you learn.
Great video and very clearly summarises the main ideas. I've been looking at other videos in the past week, but this was the best by far. Keep it up!
My Professor played this video today to mke us understand,,,
Thank u nice work
czcams.com/video/aHUv4QAXqas/video.html
Best and easiest to understand video about data analysis!
As it shows in the video, this is a matter of opinion. Mathematical statisticians say that you can only apply non-pararmetric analysis to LIkert scales. However much psychology research uses Likert scales as if they were interval data. Combinations of Likert scales form indices, some of which are validated and used extensively as if they were parametric or interval data. I think an awareness of potential issues is important, but the choice is up to the discipline in which you are operating.
This video is much-needed and helpful still after 12 years. Thanks a lot for the uploader of this video 🎉 🎉❤
My pleasure 😊
That is a really interesting question. Strictly speaking, IQ is ordinal, as we can't guarantee that the gap between 100 and 110 represents the same difference in intelligence (whatever that is!) as between, say 110 and 120. However, it is usually treated as interval data. It depends on whether you are a "nit-picking mathematician" or a "sloppy social-scientistt."
Dr Nic's Maths and Stats LOL You spelled sloppy social-scientist wrong...
@@southcabin Oops - that was a bit slopy of me! ;)
Good work , Dr Nic , I'm doing my undergraduate now this video has been very helpful .
Glad it was helpful!
@@DrNic ,
🇰🇪🇰🇪🇰🇪🇰🇪🇰🇪 Thank you all the way from Nairobi . Kenya .
Wow, this video is ten years ago. And it's useful to me today... Thank you it was hard grabbing the subject in class but this simplifies it
Yes this old video continues to be helpful still.
thanks for making this video. My understanding increase since watching your video. Keep it up
Thanks for sharing. This is very good job even for me who want to learn statistic from zero.
Very useful video. Gives the gist of data types in a simple and effective manner..
The explanation made me easily understand the topic. Found it very helpful.
Glad to hear it! Tell your friends.
I got struck in article writing which is based on statistical analysis and I didn't do it before..thanks to Allah..I have got the basics of statistical data
Happy to be of help.
@@DrNic 😃
You've made it very clear . Thanks 🙏🙏🙏 . I am a java developer . Trying to learn stats for machine learning
Glad it was helpful!
Helen looks so crazy and angry when she asks for survey participation! :) great video really helped to learn the info!
I know! She has a real attitude problem and does not model good surveying behaviour.
Thank you for making this video! It was really easy to comprehend, and I think it will well-prepare me for next year's AP Statistics!
Yup - you got it. Nominal doesn't always have numbers assigned. It is often left as text.
You are a life saver, you have no idea how much you’ve helped me ❤❤❤❤
Happy to hear it. I seem to have saved a few lives over the years
i found it much more easy and helpful ,
So incredibly helpful, thanks!
whoever made these animations is my fucking hero
Thank you very much. I got many information and knowledge from your video , I hope always stand with us. smart knowledge!
Thank you very much. Everything you uploaded is very helpful for every one . May you be successful more and more.
Came here for the module, stayed because of how well it is explained
That's good to hear
This really helped me with my psychology revision,thank you xx
The best explanation ever! Thank you Dr. Nic
Happy to hear it. The second edition is even better!
The understanding I have got about SPSS is realy interesting
This can be used for online studies. Thank you so much!
Glad it was helpful! You can see a whole lot more listed here: creativemaths.net/videos/
very clearly understood. thankyou for the good job done.
Thank you so much! You are superb in explaining things in the simplest way! Keep it up! :))
Excellent video maam. It's really simplified very well for easy understanding and superb grasping. tysm for this one.
Loving the half a second Star Trek reference in the beginning haha :D
I like the chocolate theme, actually. Even though I like chocolate, it doesn't make me feel hungry to watch these videos. It's just a nice, yummy sounding and interesting example.
wow. you explained this better than my university 4th year stats prof. thank you.
Great to hear!
Great explanation. Thank you.
Succinct and well-demonstrated. Thank you
That video has a really good explanation! Thanks for making it :)
Aha - my evil plan worked! You can see where Helen gets it from. Wish it got you to buy the app though!
No. Do check my previous responses to other questions. In stats there is little difference. It is about whether you can say that a value that is twice as much as another value corresponds to the thing being measured being twice as whatever it is you are measuring. Temperature in F or C is not ratio, though it is interval. Length in cm is ratio. Time is ratio.
The state is a nominal variable as there is no inherent order to it. You could number them any way you like as it doesn't mean anything other than a label.
Thank you from Egypt ❤️❤️❤️
You are welcome - from New Zealand!
It was a very helpful video.. Thank you
your choconutties saved my chocobutt for tomorrows exam ^_^ thank you!!!!
love the faces of levels of satsfaction :D
Yes - my son who did the good art work has a great sense of humour .
I really enjoyed this video. You reached may good conclusions that I've struggled to understand while study the nature of data and information. Like you, I spend a lot of time looking at graph types, the data they show (property and attributes that make them unique), and strength and weakness. Here are some thoughts you may not have considered.
Nominal data is not about frequency or percentage, it is a concept. Concepts have qualities that define qualifications to be categorized as "the concept." Counting and percentage is how you can quantify a nominal data set. The mean is not a way to quantify a nominal data sets, same goes for the median (middle) in a nominal data set, but the mode is an option to describe an "average." Ordering and interval is not a part of the concept of nominal. Nominal is the average/normal/typical definition or concept.
An ordinal data set is a nominal data set that has an attribute of connectivity, sequencing, between concepts. Ordering or Directionality (Example, winner or loser) Median is a measure of typical/ normal/average with the addition of a new dimension of information found in directionality or ordering.
Interval data is about distance, a weighting on directionality. A set of interval data is, as the definition of a set, can be a quantified as a percentage and counted. As it is ordinal, it has directionality. As it has interval, weighting on the connectivity, it has a dimension of length in it's information.
The average satisfaction rating.... as a #. It was ordinal, until you turned it into a interval.
Also, pie chart is not for ordinal data..... It can be, it really depends on what information you are trying to show. Information relating ordering can't be graphical show in the same using a pi chart. Pi charts are a percentage of a whole data set or subset.
If you feel I'm missing details in my logic, I'd be interested in your reasoning.
Thanks for your input.
Hello Dr. Nic, thanks so very much for your best efforts in sharing this great video on the differences of measurements in Stats. The way you presented, it is fantastic, and I can understand it easily. My best
You are very welcome
This channel is extremely informative, thank you very much.
Glad you think so!
This is fabulous! Very helpful! Thankyou!
Thanks. You might find it useful to do the practice exercises in the companion video: czcams.com/video/PLTZrQt01S4/video.html
Dr. Nic, really interesting!!! STAY BLESSED!!!
Thanks, you too!
Thank you very much teacher 😀
These illustrations are so funny, they all look villainous. Very helpful video and the narration is actually nice to listen to as opposed to some other videos where I feel like the mic must be literally in the narrator's mouth the whole time.
Glad you like them! Getting the sound right is pretty tricky.
Thank you very much for this video. It is clear and meaningful, easy to catch up. Thanks
the accent is clear, the vid is very informative---- thanks a lot
Your voice is so soothing. Thank you for this video
So nice of you. You made me laugh.
Well explained and easy to understand. Thank you!

Nice video on types of data.
Glad you liked it
Great review for me! Very clear and concise. Thanks
10 years ago recorded, still watched and super helpful :-)
Indeed! It seems to fill a need and continue to be popular. I have done an updated version that is available to channel members, which is better for showing in a class as it is higher definition.
@@DrNic thank you!!!
Thanks so much I have an exam about this tomorrow
i love u, i fucking love u. i will graduate because of ur non-sexy ass voice
Such a wonderful explanation.. thanks a lot 🙏
Most welcome!
