Question 1
Spearman rank-order Correlation
* Used as scores on both variables are in the form of ranks.
* The observations on each variable are between-subjects in nature.
Formula for Spearmans rank-order Correlations
R = 1 V 6 D
N(N V1)
Hypothesis:
H : = A=B
The ranks of A and B are significantly related
H : = A=B
There is no significant relationship between ranks A and B.

Critical value for Spearmans r: r = 1
A spearman rank-order Correlation addressed the relationship between rank-order scores for a new model fishing reel between Magazine A and Magazine B. For an alpha level of .05, the observed correlation was found to be significantly significant (r (5) = .071, p .
