Given the following series: X 10 13 12 15 8 15 Y 12 16 18 16 7 18 The rank correlation coefficient r =

Correct Answer is : 1−6[∑d2+∑i=13mi(m2li−1)12]n(n2−1)

1-{6\sumd^3+\sum_{i=d}^{2}{m_2({m^3}_2-1)}/12}/{m(n^2-1)}

1-{6[\sumd^2+\sum_{i=1}^{3}{m_i({m^2}_{li}-1)}/12}]/{n(n^2-1)}

1-6\sumd^2+\sum_{i=1}^{2}{{m_i({m^2}_1-1)}/12}/{n(n^2-1)}

1-6\sumd^2+\sum_{i=1}^{3}{{m_i({m^2}_i-1)}/12}/{n(n^2-1)}
