- This video explains about Correlation Analysis and the 2 types of correlation analysis proposed by Karl Pearson.
A complete explanation of formulae is provided. Also a complete problem solution is provided for better understanding of concept.
This concept is used in every statistical analysis and hence covered from standard 11 to post graduation studies.

mean of X - whole value, but mean of Y - decimel....entha method use pannanum sis
Even if one of the mean value is in decimal then it's assumed mean method

Ok

Why only finding which method using X alone and not calculating Y
Same doubt!
@@yodi28 since X mean itself turned out to be decimal values, it's understood that we need to take assumed mean method
BUt why ur assuming 30 for X and not other number
, pls tell the reason it wille be helpful
@@yodi28 it's the nearest value of mean we got. Also the mean value we choose should make the total final addition value as positive so chose 30
Thank you so much mam very useful for me 💗

Akka arithmetic mean method oru sum sollunga akka
Sis assumed num ethu venalum eduthukalam ahh......in our choice ahh?
It should be nearest to the mean value we got. Also ensure that the number you choose don't give final sum as a negative value
Y we take 30- and 40 as the A
It's an assumed value. You can take any value and the answer will be the same
Mam direct method eppidi mam guess panuvathu
I think you are asking arithmetic mean method...video la ye solli iruken..when mean values of x and y are whole numbers and not decimals then it's arithmetic mean method..please watch the video again for clarity
Egga mam potu erukara sum la assumed mean whole number tha mam varuthu
@@ktvtechta4040 assumed mean nah namba subtract panradhuku edukra value..video va porumaya clean ah paarunga..apo dhan endha word la edha represent panrom nu clear aagum..rendu sum potu paarunga better clarity kedaikum
Do we have take any number as assumed value?
I assume you have asked if we can take any value as assumed mean...so the answer is almost Yes. Take a value which is nearest to its mean value and ensuring the final summation of those value ends up as a positive value
Akka how to find its a direct method
Not sure of what is direct method
Sis arithmetic mean method oral ah explain pannuga pls
Please check the video. It's explained 😊
Mam oru doubt namma assumed mean na entha number venalum edukalam la apdi vera number wdutha namma final answer rum differ aaguma 😢 pls reply mam
@@Divyasri-dv5kf please take a value which is closer to your mean value so that there won't be much deviation in your final answer

Assumption x-30, y- 40 epdi eduthigha ka
Adhan assumption..ungaluku kedacha mean value ku near by value eduthukonga..ensure that the final summation of values of X and Y are not negative

@@subject360 one doubt akka if we take any value as assumed mean in x nd y.
The answer won't be wrong ahh ? Akka
@@Premv-vt3lm No you will still get the same value. Approximate ah same value dhan varum. It is always recommended to take an Assumed Value which results in a positive total value( i mean summation of all x values and summation of all y values)
Super. It is very useful to me.
Thank you 🙏🏻keep supporting 🤗
Y assumed value is 30 and 40
This is assumed mean method. So we need to assume values which is closer to the mean values we get and that value on subtracting with x and y values shouldn't return a negative resultant on totalling x and y. So took 30 and 40. You can take any value and the answer will be the same
mam en specific ah 30 eduthinga detail ah explain panunga mam
Since mean of X is in decimal, we should take an assumed value from the given samples list. I have chosen 30. When you subtract every element with 30, the resulting dx will be in positive and hence I chose it
Ok mam Thanks for the reply 💜
Wgy mam you take 30 and 40
This is assumed mean method. So we need to assume values which is closer to the mean values we get and that value on subtracting with x and y values shouldn't return a negative resultant. So took 30 and 40

Akka assumed value x and y la edukurom la athu ethu venalum eduthukalama??
When your mean value is exactly present, advised to take the same value...else take a value closer to mean value so that there won't be much variation in the final answers
