Had you taken multiple random samples of the same size and from the same population the standard deviation of those different sample means would be around 0.08 days. In a regression, the effect size statistic is the Pearson Product Moment Correlation Coefficient (which is the full and correct name for the Pearson r correlation, often noted simply as, R). The proportion or the mean is calculated using the sample. n is the size (number of observations) of the sample. http://www.investopedia.com/terms/s/standard-error.asp
