[@MrRuelTuition]

I hope it's clear now. I will elaborate more on percentiles in a revision video.

[@MCSirShiba]

This is good my brother. Please what's the name of software you used in plotting the graph? I'm Shiba from Nigeria.

[@MrRuelTuition]

Hi Shiba. Thank you. I used Microsoft OneNote.

[@rukevwwedaniel8653]

I appreciate your work. My question is why do some mathematicians use (n + 1)/4 for quartiles and other use just n/4

[@mehwishpirzada5892]

this should be (n×1)/4 not (n+1)/4.

[@rukevwwedaniel8653]

@@mehwishpirzada5892 sorry but I have seen many sources on using n+1 not n. You can check it out

[@rukevwwedaniel8653]

@@mehwishpirzada5892 There are several other sources all over the internet
