Im watching this right before my exams this afternoon 😮about 4 hours to my paper. And you've explained it so well. Thank youuu so much dear life saver.
I think we use the class boundaries to draw the polygon when it's together with the histogram but when it's to be drawn alone, we use the cumulative mid values
@@nakiryamaria1088 actually we use class boundary to draw histogram when the class intervals are non-continuos data because to draw histogram we need continuous class intervals. And we calculate mid value to draw frequency polygon without the help of histogram.
pls i hv a question from histogram and it is:What if the highest frequency is the last value to be plotted on the graph when you cross the line of the vertex with the previous one plotted before it,since there is no other one to be plotted after it how would you be able to use only one vertex to find the point/line of intersection or would it not be possible?This is my question and i also await your response..
Mode is connected to the entire distribution while the mid-value is connected to the class interval of the distribution (grouped data). The data that appears most or with highest number of occurrences (data with largest frequency) is the mode of the distribution. The mid-value of a class interval is the particular data that falls in the middle of the interval. The mid-value is calculated by adding the upper limit and the lower limit and then divide the sum by two.
That is x-y plane and this is not basically x-y plane The frequency axis is labelled 0.5 which means the intersection of f and can axes is not the origin. Okay what will you do if the first Class interval is 41 - 50?
This is absolutely the best explanation of Histograms that you will find anywhere! Thank you for this video!
tomorrow my exam and you helped me Thank you so much

Best of luck! You are welcome.
Operation “Save The Semester” was possible because of you 🙏🏿🙏🏿🙏🏿🙏🏿🙏🏿
We really appreciate your feedback.
Best of luck.
This explanation is very simple and clear.
one of the few videos on youtube where histogram is made properly
Wow! We are glad to know this. We really appreciate your feedback. It means a lot to us. Warm regards.
Thanks a lot
Good teaching
Great effort
Very helpful toe to resolve the children questions on statistics
Thanks
You are welcome.
We really appreciate your feedback and compliment.
Warm regards.
The mothers teacher is correct. Good Job
Thanks for your compliment
This is so clearly explained. Thanks
Thank you so much am sure on Monday I will write well my exam may God uplift you lecturer
You're welcome. Amen to your prayer. Best of luck in your exam.
Thanks so much.I have understood better. Sitting my exams in two days
You are welcome. All the best.
Thanks may God bless you this is really helpful
thank you sir for the brief explanation was having a hard time doing homework but I am now loving it thanks so much!!!
Thank you so much papa God bless you greatly
Thank you too
With this explanation, it's so easy.
How did make the graph?
Thanks teacher for you explanation
You are welcome.
Why did you use class boundary for the first frequency polygon and used CMV to find the second frequency polygon question😢
Thank you so much! The explanation was really very clear, which helped me a lot.
Wonderful video 👏👏
You're very welcome! We are glad you found the video helpful.
This was really helpful thanks alot❤🎉
Thanks a lot
Good teaching
Great effort
It's my pleasure
Thank you so much. Helped me a whole lot
Excuse sir how do you calculate the mean and median using a histogram and frequency polygon?
Is it continuous or discrete ?
hello sir how may i ask how did i determine the skewness of the data
To determine the skewness of a set of data we use the formula below:
Skew = 3 * (Mean - Median) / Standard Deviation.
THANK YOU VERY MUCH. GOD BLESS YOU
clearly explained,thanks so much
Sir, which apps you are using for drawing this histogram
We use Ms PowerPoint, draw and animate.
Thanks sir I can now understand histogram
Great!
You are welcome. We really appreciate your feedback.
Warm regards.
Hello when I sketch the polygon should I rub the histogram and show only the polygon
It's not necessary. Leave it like that.
Nice 👍 u really helped me u are to smart 🤓
Wow! I am glad I could help. Thanks for your kind words.💕💕💕
i love the way he explains😄
Thank you so much for your compliment.
We really appreciate your feedback.
🤝🤝🤝
Hello po sir, may i ask how did you get the numbers in frequency column?
They are part of the data provided in the question.
They are provided always
Great work thanks sir really you helped me today 🥰
You are welcome. We really appreciate your feedback and compliment.
Warm regards.
Sir can I ask question ❓ that sir in class boundary there is no krink mark because starting is 0.5 - 10.5 so there will be krink mark
It's optional to indicate the zig-zag or krink mark when the graph does not start from the origin.
Am really great thanks 👍 keep it up
Thanks sir....Great lesson
Total values of grewia hexamita is 20,18 and 10 .Calculate total number when area is 6000m2
3:26
3:27 3:27
Using 13 as origin,is it the best or I should use the zigzag sign when plotting
Use the zigzag please.
Why did you use class boundary for the first question and class mid point for the second question Sir?
We use the class boundaries to draw the histogram while the mid points are used to draw the frequency polygon.
but clas boundary and class mid point is the same , my be
@@Yolla05 No it is not

Is mode and mid value is same ?
No
Can you just explain mode and mid value
Mode is connected to the entire distribution while the mid-value is connected to the class interval of the distribution (grouped data).
The data that appears most or with highest number of occurrences (data with largest frequency) is the mode of the distribution.
The mid-value of a class interval is the particular data that falls in the middle of the interval. The mid-value is calculated by adding the upper limit and the lower limit and then divide the sum by two.
Thankyou 💥
I love it.Thankyou sir
You are welcome.
We are glad you enjoyed the video. Warm regards.
Hi from guyana ms 😊😊😊😅😊😊
Just a question what's the difference between a histogram and polygon
Thanks you so much you help me alot❤
Is it a must to start the labeling of the axis using 0.5
It depends on the nature of the distribution. So, where you start from depends the range of values of the distribution.
Do you join the lines hand freely or with a ruler
Thank you for your interest in our videos.
On your question, you join with a ruler.
Warm regards.
What If I draw my histogram without class boundaries ?
If only you can build a house without foundation.
Congratulations sir
Thanks so much for your feedback.
Warm regards.
very educative thumb up.
Thank you it is well explained I have understood
You are welcome.
Glad it helped.
hy sir how do i plot a histogram with ranges that are written as 20 -

Thank u sir
May I know where u r from?

@@OninabResources ok
Thank you so much this was very helpful
What if you are given a large number e.g150-154.….
What about a histogram scale without a scale graph possible to make please tell me about the scale
Much thanks
Thanks alot
Good teaching....
Well done sir!
Very helpful ❤
Best video on the internet
Why 8 before 0 sir ...there are no negatives ...but 8 lies on negative side
Thanks this is good
It helped alot
Frequency density?
Help me on how to calculate the number of students who got less than 28 marks
You can only do that with cumulative frequency curve
It was too good ❤
Thanks for your feedback and compliment.
Warm regards.
Where is the scale
Great respect
Thanks much🙏
You are welcome.
We really appreciate your feedback.
Warm regards.
But does the bar start at point 0 (zero ) as you start drawing the graph, or from the point of scale. 0.5?
From 0.5 which is the lower class boundary of the first class interval.
The graph does not start from the origin.
@@OninabResources but you have indicated 0.5 at point zero and the intersection of x and y axis is usually point zero
That is x-y plane and this is not basically x-y plane
The frequency axis is labelled 0.5 which means the intersection of f and can axes is not the origin. Okay what will you do if the first Class interval is 41 - 50?
yes

33-36 which is midpoint sir🙏🏿
Mid-value = (33+36)÷2 = 34.5
Excellent my lecturer!
Awesome

You are welcome 🤗
Thanks a lot sir
You are most welcome.
Please sir can you make a video on statistics when given to find the value of x and y
And to find missing frequency 🙏
Thanks Sir

It was great
