A student conducted a biological psychology practical investigation into the relationship between sleep deprivation (measured in hours of wakefulness) and reaction times (measured in milliseconds) on a motor coordination task.
They calculated a Spearman's rank correlation coefficient of rs=0.582r_s = 0.582rs=0.582. The critical value for a one-tailed test at the p≤0.05 p \le 0.05\,p≤0.05 significance level with N=10N = 10N=10 participants is 0.564.
