Q3. Independent of origin and dependent on scale

[@baasitali6065]

Thnku so much...I learnt few new formula,s which I don't know earlier.

[@hardiksangoi]

Ans for Q5 should be -1 to 1

[@kaur7259]

1:53 I have a doubt on this Q4 , Why not it is D option?
As if Correlation coefficient is 0 i.e. there is no casual relationship between them , means they are independent.
And obviously there is no negative correlation.
And it's shape is curvilinear.
So, all the options are correct.
Please tell my mistake, Sir.

[@knowledgeboost1454]

Here you have to pic what Question is actually. correlation of 0 does not imply independence. . It measures the degree to which there is a linear relationship between the two variables.. the correct answer is same
