"Good day everyone we are back together" you know uncle is about to deliver gems to change this generation
😍😍😍😍😍😍😍😍
So grateful to have you, Sir, for Maths and Physics lessons. This channel is really my go-to for revision
You want to see tears rolling down my eyes neh…
You see if I fail to obtain Level 7 at final on Maths & physics I will be the one who's having problem.Non the less Malume Mlu you know your thing 💯💯💯💯💯💯💯💯💯🤞🏿
Go for it 😃
@@MlungisiNkosi I will definitely do so.🤞🏿
Great lesson sir as always..just a friendly reminder as the prelims are nearing plz don't forget electromagnetism grade 11 lessons u promised 😂😂🔥
There’s no end it sight with you guys 🤧
@@MlungisiNkosi 😂😂😂🔥
I now understand better than before✌️🎊.. I hope you will drop another vid of statistics of histogram, outlier, varience ....
Most definitely… I spoke about outliers in our previous video.
Sir ngicela ukubuza ukuthi is (Q1 always = 25%) & (Q2 = 50%) & (Q3 = 75%)❓
Please May you do one that we are given the ogive graph and not the table and also how to find the percentile from the graph
The process is exactly the same… To find any percentile, you do exactly the same as finding the quartile
@@MlungisiNkosi look sir I knw how to calculate when it odd and even
Yes sir I did calculate the mid point
sir how do we find the median if we are given the ogive only
Sir can I ask how can I find a frequency when I am given a cumulative frequency and the middle class values only
Do we necessarily have to put a percentage after the answer or it’s correct even without a percentage
love the lesson sir but i think you a little bit too close to the camera
Thanks I’ll make adjustments in future
thank you so much for the lesson . Do we always use 25%; 50% and 75% when we determining Q1,Q2,Q3 respectively?
Yes we do
Best Ogives video in the internet ♥️🤘🏾🔥
You’re welcome
hi sir on the 2016 feb/mar p2 that you used question 2.2 on the memo the midpoint you calculated is actually the cumulative frequency so am a bit confused and also the way in which you calculate cumulative frequency is it always the method or it depends on something PLEASE SEND HELP
Thank you sir for these requested lessons❤️
It’s my pleasure 🙂
Good day sir
How do you find the modal class if they only given you the ogive?
It will where your graph is steepest
Can we not add 18 +3+2 in Question 2.3
Sir on the last example question 2.2 is there no other way i could do it ?
What method were you thinking of?
Thank sir😊you are the best 👌
You such a great teacher❤️
Thank you
But sir the 43.6 that you got is the mean right ? Not the median ?
Yes it is…
Sir could you also do a playlist on statistics so that things could easily be effective
Will do
Sir please do more questions on probability 🙏🙏especially past exams
I need to finish Statistics first
Is it correct if I started my ogive at 0 ? Not at 20❤
You always start at the lower bound of your first interval
@@MlungisiNkosi dankii sirr ❤
Sir can you do a video where the data is changed and theres an effect on the standard deviation and when there's no effect
Please check in my past exam section
Hlw where did you get 25% 75% I just hear u saying those % without showing how u got them
❤May god bless you I now understand you so great
Thank you ☺️
Mr "Favourite Uncle" can you not use , Q2=0.5(n+1) ???
Yes you can 😊
Thank you so much
Good day sir for fi × xi,isnt it supposed to be 18× 25...then 30 × 35...66 × 45 and so on as we are multiplying the frequency by the midpoint/xi?
Please correct me if i have misunderstood🤔
This is at time 14:00
I'm also confused on that part
Sir in quartile 2 why did u said 50%X100
That’s how you calculate the mean
U just followed my girl Northside doll 😅💚
Where?
Thank u sir
I highly doubt if I did the right thing.
The fact that you’re watching this gives me hope
Danko ®️ notification on

Sir can you please do a lesson on counting principle
A thank you would be nice yazi
@@MlungisiNkosi sorry sir🥵Thank you for the great lesson 😘
Thank you Grootman🙏🏼
You’re welcome
Thanks sir😁👌
You’re welcome
Sir can you please do a topic on counting principles
Please before pre-lims
I will… I promise
You awesome
And also in quartile 3 sir I don't understand cn u plz sir try to explain again
I tried to explain. It’s a percentage of n (the total cumulative frequency
Thank u sir about this lessons... I did keep on watching tht video more than 3 times and now I understand why u are using tht 50 %X100... bt if we don't wanna use tht we can also use 1/2 instead of 50% ryt neh sir?
Sir by 51:47 the number is 81, i think you made a
mistake there.
Thank you
Shoutout to you sir
Thank you 😊
can you please teach us measurement grade 11....would appreciate that al lot
🥺
Absolutely l will do so this very week
Why is Q3 75 ?
Please provide time stamp
@@MlungisiNkosi 11:19
@@atlimolokwe6302 remember Q3 is always 75% of your data
Sir is the name of learners the same thing as the frequency?
*number of learners?
Yes it is

Thank you 😊
