A set of raw paired sample data is given below. Convert this raw data into paired ranks, and calculate the value of the rs test

SOVA2 [1]

here is the data set for the complete question

x: 18 21 19 21 20 21

y; 2 14 5 6 18 18

Answer:

B. 0.652

Step-by-step explanation:

x y rank of x rank of y d d²

18 2 1 1 0 0

21 14 4 4 0 0

19 5 2 2 0 0

21 6 4 3 1 1

20 18 3 5.5 -2.5 6.25

21 18 4 5.5 -1.5 2.25

∑d² = 8.5

rs = 1 - 6[∑di² + ∑m(m²-1)]/n(n²-1)

= 1 - 6[8.5 +{3(3²-10/12 + 2(2² - 1)/12}]/6(6²-1)

= 1 - 0.348

= 0.652

therefore option b is the right answer.
