Thanks I was confused.

Hello mam
Homework ans is 0.90🤔 right or wrong
Mam agar har statement question me same hota hai toh Kearl personal actual mean method se hi nahi nikal saktey kya

Mam there is a need of arrangement of all items in ascending order
Mam formula mai shuru mai ap minus likhi thi please correct lr dijiye
0.95 is correct answer
thank you mam mujhe bahut ache se samj aaya
Thanku mam🎉
Answer 0.9544🙏
aapne assumed mean method mai bataya ki yeh formula haii..i agree and usme denominator mai aapne minus ka sign lagaya haii and jab aapne question solve kia tab minus hatake aapne multiplication ka sign use kar lia to ab ham kare kya
02:37 she cleared it!
Thank you mam so well explained
Mam how would we know if question doesn't specify to do it by actual mean or assumed mean? Please reply
Condidtions are already explained in the lecture....that when to use which method...
Maam how to know that which method to used in correlation??
i think by calculating the x and y from the question table. if the Σx and Σy divided by the n are in decimals then this assumed mean method should be used. if the x bar and y bar are without decimals the arithmetic mean method can be used.
Ma'am ne video me bola hai
Agar x bar point me aata hai to assumed mean method use karenge
If digits are greater use assumed mean method and if digits are smaller then used actual mean metho6
Missing value ka question bhi krvaoo mam...
Thanks
Thank you 😊
Tq tq tq tq tq.....❤❤❤❤
Thankyou Ma'am
