Can someone please tell from the information given below, which equation (Pearson's r or Spearman's) would be most accurate and why?

Pearson' s r= 0.906477

Spearman's = r=0.9779

Comparing two APGAR results from two doctorss gave a mean difference and standard deviation of:

Mean = -0.1875

SD = 0.981

t= 2.04

n=30 (16 from doctor 1 and 16 from doctor 2)

the degrees of freedom here are 16 + 16 - 2 = 30

After calculating the 95 % CI I came to a result of (1.3085, 1.6835)

The question is, which equation is most accurate and why? Thanks everyone!

Given the information you have provided it

**appears** you have a bigger problem on your hands.

More specifcally, given the degrees of freedom (30), your

*t*-statistic is based on a two-independent samples

*t*-test (Right?).

And, it also appears that the Pearson correlation between the two doctors data points (n1 + n2 = 32) is r= .906477 (Right?).

Before I go any further, can you tell me that my assumptions are correct. If not then you should present you information more clearly.
