im paying $1400 a term for this subject through Uni... this free video taught me what my paid course couldn't. ffs. thank you.
Same here😂😂
best video .. appreciate your efforts thank u again ❤️❤️
Bahut badiya se samjhaya....thanks
great presentation and explained in a very simple language
Thank you :)
thank you for this statistics playlist. helped alot
WOW....easy and informative ❤️
Thanks for clear explanation
Thank you so much mam. it was very informative.
Perfect explanation👍🏻
beautifully presented, thank mam.
Love u for making this video
very helpful, thanks from Turkey !!
Thank you so much ma'am
This was helpful thanks!
Actually I have attended my Ph.D entrance exam today. Nearly 3-4 questions come from dis topic and I clicked the answers without any doubt only bcz of ur video. Thk u soo much mam
Great ❤
This was helpful! I got confused with the ratio example where you say, you can say 2 is half of 4.
Thanks
❤❤❤❤
finished watching
Can you please explain why interval data doesn't have a meaningful 0 ??
Because 0°c is very much possible
Hi, I would like to ask the time of sport is interval or ratio ?
How does weight have a meaningful zero?
IQ can’t be negative and it can be 0. How is it interval data?
But IQ scale can't be zero.
@2:10 How come temperature doesn't have a meaningful 0 if O degree celsius exists?
Meaningful zero means where zero means nothing but in temperature zero shows temperature
I suggest removing the music it's so annoying 😵💫
BTW Ur videos are so useful
What is the difference of numerical data to quantitative data? Our lesson says quantitative data is the one that is divided onto continuous and discrete
Continuous data is a numerical data type with uncountable elements. They are represented as a set of intervals on a real number line. Some examples of continuous data are; student CGPA, height, etc.
@@learningchampion so what is the difference of numerical data and quantitative data?
Quantitative data is one type of numerical data!
How can dates be negative ? Are dates an example of Interval data ??
Dates are interval data as dates doesn't have any starting point. Also, interval data can be negative but it is not necessary that all the interval data will be negative.
age is ratio ???????
Age is considered a ratio variable because it has a “true zero” value aka a starting point.
How date is interval like date can't be negative ,
Even though date can't be negative, there is still no starting point. That's why it is considered as interval data. Interval data can contain negative values but it is not necessary.
@@learningchampion thank you 👌🏻
How does temperature not have a meaningful zero. 0 degree celsius = 32 degree farhenheit
By meaningful 0, we mean a starting point and temperature clearly doesn't have a starting point. We don't know which value is the lowest value.
To have temp of 0 could mean several things due to 0 degrees Fahrenheit meaning something entirely different than 0 degrees Celsius.
and by meaningful zero, that’s the same as saying unique zero (ie there exists one and only one characteristic associated to 0, regardless of unit).
If you have x offspring, then unless you redefine what it means to have an offspring or what zero is, you must have x offspring no matter what way you count it.
Brother I got that. Absence of absolute zero means, that there is a zero value but that zero value is not absolutely the lowest value. There are still smaller values than zero. For example, in temperature we have 0 degree celcius but we also have -1 to -n which is lower than zero.
But in ratio scale there is no value lower than zero like in example of age or weight or height it can be measured very low as zero but can never be less than zero.
@@learningchampion There it is.... this is exactly what I was looking for. "True Zero" is very confusing by the title! Thank you :-)
What does meaningful 0 mean?
By meaningful 0, we mean a starting point. Like 0km is starting point of distance, temperature clearly doesn't have a starting point. We don't know which value is the lowest value.
What Ratio data has to do with ratio. Why it is called ratio data?
Ratio Data is quantitative data where there is an equal and definitive ratio between each data. Also, note that there is an absolute “zero” which is treated as a point of origin.
Here because my professor for my stats college course is a TERRIBLE teacher. College is such a scam 😒
Temperature can be zero
Temperature can be zero but negative temperature is also possible. That means it doesn’t have a true zero aka a starting point. If something has a true zero it cannot go below that zero like age.
@@learningchampion How can the age be negative ? never heard of someone that is -3 years old , also i googled if the ratio values can be negative and found that yes they can be
so i'm seriously confused right now
Ratio data don't have negative values. Age can never be negative.
Why ratio is not possible in interval?
Meaningful 0 ka concept achi tra smaj nhi aya..
Meaningful 0 is the starting point. Age has a starting point which is 0 but temperature doesn't have a starting point.
@@learningchampion Thanks for this! Could you explain it in a little more detailed manner though? Having a true 0 means what exactly?
By meaningful 0, we mean a starting point. Like 0km is starting point of distance, like 0 age means the baby is just born. Temperature clearly doesn't have a starting point. Temperature below 0 is possible and we don't know which value is the lowest value.
