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 .
