Descriptive Statistics And Two Tailed Bivariate Pearson Correlations Download Table from www.researchgate.net
You will often see a statistical test or a hypothesis referred to as one-tailed or two-tailed. Use these two bivariate regression equations estimated from the 2008 GSS data to calculate some predicted values. With respect to One-Tailed and Two tailed test of significance while in case of one-tailed test you as a researcher are proposing that there is one possible relationship between the two variables which are being tested and that either the variable is higher than mean or lower than mean however in case of two-tailed test we are speculating that these variables can.
Hypothesis tests may be one- or two-tailed.
The mean is considered significantly different from x if the test statistic is in the top 25 or bottom 25 of its probability distribution resulting in a p-value less than 005. Power analysis for a Pearson correlation was conducted in GPower to determine a sufficient sample size with an alpha of 005 a power of 080 a large. Once I get those values I would simply divide by 2 to get the one-tailed level of significance. Before calculating a correlation coefficient screen your data for outliers which can cause misleading.
