In this lesson, you will learn about the interquartile range of data, also known as IQR. First, we must break up the data into quartiles, which divides the data into four equal groups. The interquartile range is the difference between Q3 and Q1, which is the third and first quartile. In this way, we can throw out any outliers and focus on the bulk of the data. The IQR tells us how spread the data is without considering outliers in the data.

Great explanation on IQR, I never really quite understood what I was calculating before. I just memorized 1 st Q minus 3rd Q for IQR ?! I wish I had seen this before my GRE . Great job as always Sir .Merry Christmas!
you explained how to find the interquartile range very well, thanks for sharing, happy holidays
I get it sir! This is dealing with making the most rational choice from the numbers available. You throw away the high numbers and the low numbers and stay in the middle! This would be good for somebody that played poker! WOW...numbers are fun when you really study them! Very exciting!
Well understood.thanks
Merry Christmas.
Are all these newer videos available in your purchasable course? Also merry Christmas!
Very good teaching
Hi, I am a member on the site and I was wondering under what topic I could find this video? I can't seem to find it anywhere.
Thanks!
hello sir, thank you for this very nice educational video, can you make also a video on electrical about grounding? how it works when ground fault happen and how does it related to esd in electronic devices. thanks
Grounding protects us from electrical shock whenever we touch a faulty electrical equipment.
OFC! it all makes sense now.
It is very difficult but after several viewings I see the math. Thank you. But how is it translated? For example, in the second problem, what does the answer 9 represent? Age? People? The problem refers to double digit retirement ages. In problem three, what does the answer 5 refer to? Donuts?
Thanks a lot! it was verry helpful to me! I subscribe your channel with pleasure!
Sweet 👍
It's interesting to see how IQR throws away outliers.
plz make any way to arrang leson i can not find it leson 1 2 3 4 for one leson plz writ the name ans leson num and paer num
🙏 Thank you for answering my million-dollar question... 😆
It would be nice if there was an underground world with great developments of people and are education was kinda on a youtube video .
What is the advantages of inter quartile range compared to the total range of the data
IQR throws out the outliers on either end of the data. If you have outliers this is a better measure of the range.
would have been nice to show an outlier problem; but i''m just an outlier myself.
