Document Summary
Beta weight specific coefficient between -1. 0 and +1. 0 used in a regression equation to represent how much weight a particular variable should have in predicting an outcome variable. Bivariate regression statistical analyses that allows for the prediction of scores on a dependent variable based on scores from a predictor variable. Regression - predicts outcomes: standardized reduction analysis, unstandardized regression line. Hypothesis testing determining if some effect in a sample is likely reflective of patterns in the population. State the research and null hypothesis (using formulas and symbols) Describe the comparison distribution (draw the normal distribution) Determine the critical/cut-off score and related alpha region. Determine the score that best represents your sample and compare it with the critical value (find the z-obtained) Comment on the null hypothesis/determine if your sample is unlikely to come from the population represented by the comparison distribution.
