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 sir I really appreciate what you are doing for as 🙏🙏🙏🙏🙏 maybe God bless you

Thank you so much sir for your experience we really appreciate❤❤

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.. though I didn't see you subtracting the mean from the data set kindly clarify

Thank you sir this method is simple

Aren’t we dealing with ungrouped data ? The formula used is grouped data

Thank you its very helpful

When finding the final you didn't divide by 30 y.

Thank you sir❤ I appreciate

Thank you 1000x

This is a good formula but can I use this in an exam

What about the formula where we must use a table

why are we using the formular of grouped data while dealing with ungrouped data

What about if your assumed mean,how will you go about

Sir why are you using the formula for grouped data whilst that was ungrounded data you confused us otherwise, check very well

I would love to join your class

Thanks Very much

The formula sir, can work on both grouped and ungrouped

But,sir,why some other teachers discourage using this formula,,,am enjoying the lesson ❤❤

Please sir you help me with paper 1 maths

Kindly sir am still struggling with how differentiate grouped data from ungrouped data. Kindly I need your clarification.

Sir I have a question. Is this not ungrouped data? Why using the formula for grouped data? I stand to be corrected.

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

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

Thanks very much sir

That's not the answer am getting sir

So sir even if we try to use that other formular fo ungrouped data we will still find same answers

Sir, so you can use the same formula for grouped and ungrouped

Sir... when finding the final answer, why didn't divide by the frequency 30 why?.

What about if your assumed mean,how will you go about
