We want to assess the relationship between romantic relationship satisfaction and education. We are able to obtain data from 8 participants to survey and we have participants rate their satisfaction as either extremely unsatisfied, moderately unsatisfied, neither unsatisfied nor satisfied, moderately satisfied, or extremely satisfied and then report their education level in terms of the highest degree attained. Because the two variables are ordinal, we want to compute Spearman's rho to assess if there is a relationship between these two variables. What would be the denominator for Spearman's rho? Please report your final answer to the nearest integer.
