Sir please help, I have been answering using this same method but my teacher said I should stop because it doesn't belong in mathematics, you can only answer that in biology. I don't know the table one and I don't like it but I don't know what to do
Your teacher is probably not as exposed to other mathematical methods and is glued to only one. Using this method is okay and you can use it for ECZ, since your teacher won't be the one marking.
Thank you so much we have nothing to give but may the almighty GOD grants you all your need in Jesus name amen❤❤❤
Thank you.. though I didn't see you subtracting the mean from the data set kindly clarify
Its a good formula actually now is it allowed to use it in an exam using the same formula for both ungrouped or group data
Thank you sir I really appreciate what you are doing for as 🙏🙏🙏🙏🙏 maybe God bless you
Aren’t we dealing with ungrouped data ? The formula used is grouped data
why are we using the formular of grouped data while dealing with ungrouped data
Am also wondering
Thank you so much sir for your experience we really appreciate❤❤
Thank you sir this method is simple
Thank you ❤
What about if your assumed mean,how will you go about
When finding the final you didn't divide by 30 y.
Thanks Very much
This is a good formula but can I use this in an exam
So sir if we use this method there is no problem coz other teachers use a table,is it the same?they will mark us same? Your method is simple
Both are okay 👍
Is this not ungrouped data? Why using the formula for grouped data? I stand to be corrected
Yes, it's also my observation.
Sir why are you using the formula for grouped data whilst that was ungrounded data you confused us otherwise, check very well
Kindly sir am still struggling with how differentiate grouped data from ungrouped data. Kindly I need your clarification.
Or is this belongs to grouped data or ungrounded?.
Thank you 1000x
I would love to join your class
Thank you its very helpful
Sir... when finding the final answer, why didn't divide by the frequency 30 why?.
I was thinking the same. He forgot maybe.
@@RichardBanda-xo6ck I think so

@@techsolutions5136 ok thanks dear
The formula sir, can work on both grouped and ungrouped
Yes
@@jacobsichambaonlinemath5090❤
What about the formula where we must use a table
Sir I have a question. Is this not ungrouped data? Why using the formula for grouped data? I stand to be corrected.
The process is the same, unless if we didn't have the frequency.
Sir u don't have a frequency how can you solve
@@febbymilimo-vu4er are you sure you can't see the frequency?
Thank you sir❤ I appreciate
Thanks very much sir
You are welcome
Please sir you help me with paper 1 maths
Sir, so you can use the same formula for grouped and ungrouped
Yes depending with the nature of the question.
So sir even if we try to use that other formular fo ungrouped data we will still find same answers
I also had the same question?
But,sir,why some other teachers discourage using this formula,,,am enjoying the lesson ❤❤
I don't know why, you are free to choose what works for you.
I think this formula is easy and straight forward think about the time they give in an exam, drawing up the table can chew a lot of time
That's not the answer am getting sir
What about if your assumed mean,how will you go about
