Hi Cody, that was awesome. I've been struggling with statistics all my live but am ever curious, and this really gave me a push in the right direction! You've got a great gift of explaining, thank you for making that video.
Cody This video is very very useful I have a question about a problem that maybe you can explain me the way you show at your video. This is about how to find the variable value for which the probability is about a stated value, like this next: Which is the value of "t" for a normal distribution N(1,0), mean 0, standard deviation 1, the probability stated is 0,80, the condition is P( -2 t < Z < t ) I´m a little bit confuse about how to calculate it I would appreciate a lot your information Thanks in advance
I am trying to figure out how to plug this into MS excel. Is it possible to do so? Assume that a population is normally distributed with a mean of 100 and a standard deviation of 15. Would it be unusual for the mean of a sample of 3 to be 115 or more?
Hi Cody! great video. Can you pls tell me what formula did you use to calculate the "Area" of the "range" (59.8 - 70)? As "Norm.Dist" function doesn't allow to calculate the range!
You would not want to share how you got it would you? I've been trying to sole a problem for the past 2 hours only because I don't know how to do this in excel.
oh - well just off the top of my head, if you want a range between values.....REMEMBER, that this finds the area to the LEFT of a number. So let's say I want between 6 and 10. I would find the area to the LEFT of 10 then subtract off the area to the LEFT of 6. Leaving the area between 6 and 10. Does that help?
OSSovik You don't. You create it by watching the video! The point is to also learn how to use EXCEL. There would be no learning if I just gave you the document and you clicked a button.
Great Article; Can I CREATE a graph to show the results? (Area between z-scores) Similar to your hand drawn one, but based on the actual data in the chart?

Thank you for this video. I struggled with this area and you helped me to get through it! Thanks a billion!!!
Thanks for the video! It really helped. I also shared the link with my Stats class so they could watch too if they were having problems!
Hello Cody, this video was very helpful , do you have a similar video for Poisson distribution
Naveen Jolly I have not. As this was just for an elementary stats course and we don’t cover that topic.
Really good tutorials!
Great explanations! Thanks!
thanks for posting, just what I needed!
Hey Cody, Great video. Do you have a video on creating an excel sheet that you used to complete the calculations?
i'm having trouble understanding the z score and the table. which part of this excel sheet gives us the number from the z table?
Great Information...thanks!!

can you show how you made those graphs from d beginning?
U are really good In exel
In the norm.dist formula, what does selecting false for the cumulative option mean?
I think selecting false gives you density rather than cumulative distribution.
Thank you!!
U just got another subscriber

Got it!! :)

you say "got it", but I have no idea what you are talking about. You have to be specific.
Sorry Cody, I wasn't expecting you to to reply, I was replying to Nitin who mention they got how to a range to work with normal distribution.

Where can we download this xls file you re using?

What is the equivalent on a mac i select norm dist and it doesnt give me the same window as the one you got
nvm figured it out

hi sir, i have daily data of rainfall, if i snd u my data, can u will analyze it for me according to normal distribution in excel...
thank you so much.
thanks a lot
