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.
The positive value of k for which x 2 +Kx +64 = 0 & x 2 - 8x + k = 0 will have real roots . Ans: x 2 + K x + 64 = 0 ⇒ b 2 -4ac > 0 K 2 - 256 > 0 K
