Summation of X = 20
Summation of Y = 20
Summation of X^2 = 90
Summation of Y^2 = 90
Summation of X.Y = 73
X bar = 4
Y bar = 4
COV(X, Y) = -1.4
Sigma X = 1.4142
Sigma Y = 1.4142
Coefficient of Correlation
r = -0.7000134263
Solved

[anasshaikh]

x̄ and ȳ = 4 ,
sigma x and y = 1.4,
cov(x, y) = -1.4,
r = -0.70

[abhishekak]

Thankyou sir 🙏 Excellent teaching sir
Answer is -0.70

[yashrao]

Literally the best vid for this chapter ❤😊

[raghvdhir]

Sir I just very thankful to you. I was totally dependent on your lectures and today was my MST of math of topic partial differentiation and differential equations. I totally studied from your playlist and today I knew everything in paper and it went very good

[PUSHKARSINGH]

lots of power to you brother
keep it up

[CAROHITYADAV-kk]

Sir, I got the answer
The correct answer is = -0.7

[Snowflake]

Thanks alot for helping with this!!!🎉🎉🎉

[Frankly_One]

sir actually exams main share and like karneka har kisike pass time shayd nahi hota lekin sir sach main dil se thank you sir jiii❤❤❤❤💝💝💝💝💛💛💛💛

[nikitakhurgade]

Thank u so much sir for your useful content, I want really appreciate for your work and dedication sir, it's lot help for me

[UE_devlover]

ye cal c may pura solv ho jata hai
statistics may ja k fir Y=a+bx vale may ja kar x col, y col fill kar k fir AC uske baad fir se statsics may jak summesion may Janeka ans mil mayenge

[rohitkhedkar]

thank you sir it helps for passing m3 🤩

[AEvlog]

Thank you so much sir 🙏 for your good teaching 🎉

If you put sigma x&y = 1.414213562 then ans is -0.49498.
But if sigma x&y = 1.4
Then ans r= -0.71 so
which one is correct? Plz reply

[VedangRaul]

the answer of the last question is r=-0.7041

Please conduct lectures for Statistics subject 2nd year computer engineering 🙏🙏🙏🙏🙏🙏

[saniyashaikh]

Sir probability and statistics ka leya konse book refer karna

[sayyampokale]

Assumed mean method me bhi yahi steps and formulas use karne hai?

[manvijain]

Sir how to solve this que...Show that E (x) = 0, E (x, y) = 0 and hence deduce that the correlation between x and y is zero.
