Omg this was very helpful I have a group research ang I'm assigned to the Organizing ang Presentation of our data. So this helped me alot for my FDT and visualization for the normality of distribution. Thankyou verymuch!!
THANK YOU there isnt any video like yours, i find this hardly it was very non understandable how can distribution be like a curve, how create by own and understand the whole process, Thanks a lot))))
When you're correcting the y-value for the normal distribution (norm.dist) did you say add 5000 times 5? (=norm.dist(cell, cell, cell)+5000*5? Or =norm.dist(cell,cell,cell) *5000*5? Your cursor covers the exact spot to see if you added or multiplied the 5000*5.
Yes he did but it is "*" and not "+". You can also use = norm.dist(cell, cell, cell)*COUNT(range of cells of main data)*(The difference between two bin data points) For the difference use $ signs to fix the cells (or F4) Then you don't have to manually calculate the number of data points you have manually and don't have to calculate the bin difference either and can use this for any data set.
The sum after applying norm.dist function is not coming 1 in the y column (before applying correction multiplication). what to do please help. My data does not contain integer values; it has decimal values (float), and I have taken all data values as X.
Thank you so much however, when I try adding the curve, my normal graph (lets say series 1) goes down. Now I have a curve way over the actual graph. Theres jut something Im missing
You should put a link to download the excel template that you used in this tutorial so that viewer could follow what you did, otherwise I will give you a thumb up.
I cant seem to move the normal distribution to the right because when I click on the histogram it doesn't highlight the bins in purple but the X values
Hi, I'll try to explain. When you click on the histogram, you need to make sure that you click in the middle of and at the top of one of the bins. That way you select the histogram. When you click on the histogram nearby the normal distribution curve, this curve is selected instead. Another way to move the normal distribution to the right is by clicking on the graph, selecting Chart Design in the ribbon. Next, you click on Select Data. A menu opens where you see two series. Series1 should be the histogram. You click on this one, select Edit, and change the x-values to the midpoints of the bins by inserting the range H3:H13. You click on Ok twice and the normal distribution should move to the right. Hope this helps.
Hi, I'll try to explain. If you plot a normal distribution curve, the area under the curve is 1 by definition, while the area under the curve is way bigger for our histogram. If you don’t correct the y-values for this, the normal distribution curve will appear way too small on the graph compared to the histogram. So, we need to correct the y-values such that the size of the area under the curve for the normal distribution is the same as the size of the area under the curve for the histogram. As the area under the curve for the normal distribution is 1, we only have to multiply this by the area under the curve for the histogram in order to end up with the same size. To compute the size of the histogram we have to sum the size of each rectangle that is part of the histogram. To compute the size of one rectangle we have to multiply the width by the length. The width is 5 as we chose a bin width of 5 for our histogram and the length is the number of observations that falls into that bin. Since we have to do this computation for each bin and hence we capture all observations, it suffices to multiply the bin width by the total number of observations. I hope this helps.
The total number of observations 5000 and width of bin 5 I am right, sorry if I bother you again. Can I have your work Excel sheet please? High priority!
@@Aishasadventures7809 Hi, sorry for the delayed response. I added the file to the website. You can download it from: softtechtutorials.com/microsoft-office/excel/excel-histogram-with-normal-distribution-curve/
Can I save the work and reuse it by refreshing the input data and have the curve updated accordingly? I’d like to use it to show distribution of students’ marks as there are new quizzes and exams without having to do the steps from the beginning.

Oh my god! Finally! THANK YOU VERY MUCH! You saved our team! Much love and respect from department of biochemistry in Greece! (Eva, Spyros, Giannis
Thank you! This is the best explanation and practical instruction on this topic that I have seen on the internet.
You're welcome! I really appreciate the kind feedback.
Omg this was very helpful I have a group research ang I'm assigned to the Organizing ang Presentation of our data. So this helped me alot for my FDT and visualization for the normality of distribution. Thankyou verymuch!!
Wow. This really saved my day. So much better than the other explanations I clicked through before finding this. Thanks!
Very helpful video. Really impressed my colleagues with this one!
Ty so much for showing howto add the analysis toolpak
THANK YOU there isnt any video like yours, i find this hardly it was very non understandable how can distribution be like a curve, how create by own and understand the whole process, Thanks a lot))))
How did you determine the "mid point" here? and what is the difference between it and the "end point"? Thanks.
Saved an entire work my friend, congratulations
Thank you sooo much. I have been trying to find a guide to this for sooo long and finaly something what I understand.🙏🙏🙏👍👍👍👍👍👍👍👍
Lifesaver! Thank you so much!!
Good Work, really helpful
This really help a lot for me, Respect!
If this is the quickest way to do it, the developers should be fired for not having a trendline available in histogram
👌☺️😍
THANK YOU FOR THE EXCELENT EXPLANATION. COULD YOU PLS EXPLAIN WHEN ERROR BARS COME VERTICALLY WHAT CAN WE DO?
thank you so much for your great explanation. I really understood it. how about Excel Histogram with Normal Distribution Curve for a Likert Scale Data
really good! Thanks.
Thank you. It was very useful.
You're welcome. I'm glad to hear it

Awesome, very helpful!
You're welcome! Glad it was helpful
Why dont use answer to the questions about mean and standart deviation? How did you get it?
5:34 why is it multiplied by 5?
There is the certain formula to find bin width. ;)
great video! 8/10
I'm looking to get the percentage of the histogram outside of the curve, is that possible?
Excellent
Thank you so much however, when I try adding the curve, my normal graph (lets say series 1) goes down. Now I have a curve way over the actual graph. Theres jut something Im missing
at 6:25 when I am changing scatter from no line to solid line, I am getting too many lines connected to each other.
Where do you get the "X" value?
the time I deleted the error bars, my graph was gone. What happened
5.28
Brother, where did the 5,000 come from?
You should put a link to download the excel template that you used in this tutorial so that viewer could follow what you did, otherwise I will give you a thumb up.
How did you get the mean and the standard deviation so fast
He just did not show them in the video. Use average function and STDEV.S(range)
Why do we have to multiply by 5000?
How can got x value from histogram please, good work thanks 😊
I have a data set with averages. Am I still able to use the normdist formula ? or is there another way ?

Another question. How can I calculate frequency -15 against bin value 150?
How did U find the midpoint in the bin??
Here student Number is 31. Your frequency distribution in Bins is more than 5000, How is the procedure to calculate like you
Another question please why you multiply y by 5000*5 please

Since we have to do this computation for each bin and hence we capture all observations, it suffices to multiply the bin width by the total number of observations.

5000 how many students do you have and 5 for bin or it’s constant??
@@SoftTechTutorials89 very helpful thanks a lot

how did you find the variance please?
are we supposed to take mean and standard deviation of our x values or original values
the mean and stdev of the original values. he posted the link where downloadable file could be accessed in the comment section
How can I add control limit lines on this histogram
hello I am failing to download the excel sheet - is the link working ?
Can I save the work and reuse it by refreshing the input data and have the curve updated accordingly? I’d like to use it to show distribution of students’ marks as there are new quizzes and exams without having to do the steps from the beginning.
Do your own homework! 😂
can any one help with file - failing to download
Why are we multiply by 5000 sir
Because he has 5000 respondents, 5000 students
Do you have the workbook to this tutorial so I can follow? Thanks.
Sure, where can I send it to?
where can i download the excel sheet
how you gonna make a tutorial video and then cut an edit in with new things done????
The worst video explaining this
