I've taken your first row of data and built a column in an Excel spreadsheet with 21 fours, 49 threes, 287 twos, and 143 ones. Using the data in this column, I can replicate your calculation of the mean and standard deviation for these values. However, using Excel's StDev formula, I arrive at a standard deviation of 0.7364 for the values. This result can be verified using Descriptive Statistics in Excel's Data Analysis package. Why is there a difference in these results compared to yours? Am I missing something?

This is great but you did not provide your contact, is a unique explanation

Perfect ❤

To calculate the SD i tried it, like this = Sqrt(F2:G2) Is not giving me the answer

Thank you so much but you got the standard deviation wrong

Source code please

Where did you find the factors of the second mean?

👍

Please how can I analyse my ,5 likert scale questionnaire. Okay I have 3 research questions and have 10 questions each, with a population size of 68

Your interns did well

Thanks a million

this video was so helpful, thank you!

Thank you sir , this video came in handy for me today. Have been battling with this for 2 days now. Thank you ,God bless you . More grace sir

I love the seriousness and passion! Your interns are doing great 👍🏾

This is a real practical center as I perceive!

This is awesome ❤

well well well

Wow

Good job 👏

Nice!

Good job sir. But I think one thing is missing. You have to squareroot the first mean before subtracting the 2nd mean from the first then square the answer before you get STD. Example.55 SA, 6 A, 25 D, 14 SD. Total response is 100. The first mean is 3.020.....STD from SpSS is 1.17. I want us to apply this method to see if we can get the STd.

What symbol he used when he say 5:13 , the difference of first mean of goods and these? Is that a - symbol?

Today, I'm preparing 2nd Research Paper. I learnt now how to calculate mean & SD. Really Sir, Superb!!!!!!! May God Bless you.Thank you so Much, Sir!!!!!

you saved me....thank you so muchhh

Excellent guys

Super proud of you all. GOD bless you

Why squared the points?

THANK YOU VERY MUCHH SIRR!! THANKK YOUU!!

But why 16, 9, 4, and 1?

thank you! this helped me with my UX project.

Why the {0} and {1} if you can do something like this: Console.WriteLine("Hello, " &variable& "!")

Good video! 👍 i learned new things!

I forgot my language after listenning this😂

Thank you so much! This is so helpful!

Bro doesn’t even know how clutch he is rn

thanks

Sir we have a query, we asked 25 questions to 400, and there is 4 category in age groups 20-25, 25-30, 30-35, we want to calculate mean and standard deviations of opinion of each age group.
