Weldone, but this graph sheet is 1cm not 2cm

[@DavetutsAcademy]

Thanks Tambuwal. You should understand it's representative. Making best use of the digital space warrants the scaled adjustment. But the prep for K12 students warrants staying in the bound of their understandable scope. Students get it and it's obviously stated in the video too

Sir a quick question its not part of the workings in this video its just a personal question relating to calculating quartiles and percentiles : so like if we end up getting a decimal after calculating 25%of50 do we round up the 12.5 to plot on the graph or u put it as 12 on the graph. Its just that im solving a question like that. Thank you Sir ❤❤❤

[@DavetutsAcademy]

You need to factor it into ur graph. I your scale puts 12 and 13 on unique sequential graph lines, then you locate the space between them. But if the scale puts 12 and, say, 24 on sequential lines, you have to use the 12 approximately.

[@macmillanquansah6177]

sir pls the meaning of the 5 divisions,,i dont understad..u said each box is divided into 5 divisions ..how pls

[@emilyjohnson4695]

Sir do u solve chemistry theory questions

[@DavetutsAcademy]

Not yet; maybe later. 👍

[@dasage6104]

Sorry what if u have yr cf up to 360

[@DavetutsAcademy]

Continue with the same concept and scale the graph to cater for all the values as appropriate

[@omowunmiakinbode54]

You are a darling sure♥️

[@lolaozoh3879]

Can we just mark the origin of the graph as 0.5 instead of 0. It's kind of hard to see what you wrote on the x axis to indicate that your origin doesn't actually start from 0

[@DavetutsAcademy]

No please. Just draw two "W" that is sitting directly on the thick red line starting from the origin and that will be fine. All the best

[@khadijatrawally1946]

I dnt understand how u got the 95/100

[@khadijatrawally1946]

Letter C the 5% distinction

[@DavetutsAcademy]

It's gotten by subtracting the 5% that got distinction from the 100% which is the total of them all. So we have (100-5)% = 95%

[@Streetballer10]

@@DavetutsAcademy where did you get the 100 percent

[@DavetutsAcademy]

Great Man, a complete data set will be considered as 100%. Other percentiles are scaled from it subsequently. Hope it's clear.
