Spurious Correlations
- in several rare situations when plotting the data for x and y we may have a group indicating either positive correlation or negative (-ve) correlation but when you analyze the data for x and y in general life there may be no convincing evidence that there is such a relationship. Therefore this shows that the relationship only exists in theory and thus it is referred to as spurious or non sense for illustration, when high pass rates of student show high relation along with increased accidents.
provide a real-world example or scenario that can be express as a relation that is not a function
If there are (2n+1)terms in an AP ,prove that the ratio of the sum of odd terms and the sum of even terms is (n+1):n Ans: Let a, d be the I term & Cd of the AP. ∴ ak =
If the p th term of an AP is q and the q th term is p. P.T its n th term is (p+q-n). Ans: APQ a p = q a q = p a n = ? a + (p-1) d = q a + (q-1) d = p
Utilizes the definition of the limit to prove the given limit. Solution In this case both L & a are zero. So, let ε 0 so that the following will be true. |x 2 - 0|
for what value of k,the following system of equations have infinite solutions?kx + 5y -(k-5)=0;20x +ky - k=0
