Thank you! Glad it helped

[@m00sing]

Thank you for this. Just a little confused on why we include all points in the first half/2nd half when we have even data points vs. only looking below/above the median in an odd data points scenario.

[@m00sing]

Never mind, I see it now. Halves matter.

[@isaiah352sharon9]

Thanks very much

[@rohitguin1844]

ma'am do we need to arrange the data set in ascending or descending order in order to find the quatiles or we need to use the data set as it is?

[@MathandStatsHelp]

The data set has to be in ascending order.

[@mkhan2041]

Nice one

[@kimberella2105]

Thank you! I needed to know what q4 was because I was confused

[@MathandStatsHelp]

Glad I could help

[@kimidora6553]

Hi, i would like to ask. What's the difference between that method and the method that has formula using k(n+1)/4 . Thank you

[@MathandStatsHelp]

I'm not familiar with the formula you shared. There are a lot of different methods used in math.

[@Bigsteppa34]

Thank you our teacher has used as a example in math

[@Bigsteppa34]

I’ve never had anyone pin me so fast wow

[@MathandStatsHelp]

I happened to be on my app at the moment

[@Bigsteppa34]

O well that make sense

[@hrithikmanglal-a2679]

using the method you used can you calculate q1 for 1 to 12 numbers R statistical tool says its 3.75 what you say?

[@MathandStatsHelp]

R does a different method of calculation. Both are acceptable methods.

[@eshaanrai2712]

Hey amazing vid but could you please also make an video on inter quartile range. IDK y in my book its given as Q3 - Q1,shouldn't it be q4 - q1 ?

[@MathandStatsHelp]

The interquartile range (IQR) is found by Q3-Q1. It is the range of the middle 50% of the data. It is resistant to outliers, where the range (max-min) is not. This video that I have shows how to create a box and whisker plot. I use the IQR to find outliers. I show how to find the IQR: kzbin.info/www/bejne/gZ2ZYZiCgM6rbdU . Hope it helps.

[@laylayalexandraysabels.9208]

Do I need to round off the 3.5 if ever I encounter an answer like this in getting the quartiles? Thanks btw, it's not confusing anymore.

[@MathandStatsHelp]

If you get something like 3.5, just leave it as is. Glad you're not confused anymore.

[@megatmuhammadikhwanbinmega8075]

you're an angel.. thank you for your help😁love from Malaysia.. I've question...my data is 7,10,11,12,12,14,15,15,16,23,26... how to find Q1 and Q3

thank you my lady

[@abbull_3000]

What software/hardware do you use to make your videos?

[@MathandStatsHelp]

I write on a monoprice graphics tablet, I have a USB microphone, I use SmoothDraw4, and a free screen recorder called Ispring.

[@abdirahmanabdullahi2436]

How do you find the inter quartile range I mean do you just subtract the first quartile and the third quartile

[@MathandStatsHelp]

Yes, you just do quartile 3 - quartile 1.
