hypothesis predicts a correlation between two variables
Data is related
Design is correlation
data is ordinal, interval or ratio

What is needed for spearman's to be significant

Chi-squared

predicts a difference between two conditions or association between variables
the data is independent
Independent measures as each participant is only in one condition or correlation
data nominal

What is needed for Chi-squared to be significant
