Dear Students in PSYC 2101:Here I show how to get the correlation/regression analysis:Descriptive StatisticsMeanStd.

Don’t you be making any of these errors.Not identifying the subjects. They were working professionals, as indicated in the abstract at .Reporting an incorrect value for power.Reporting incorrect values for the confidence interval.Reporting an incorrect value for the t or the F.Reporting an incorrect value for p or no value for p.Reporting an incorrect value for the slope or not reporting a value for the slope.Reporting an incorrect value for the intercept or not reporting the intercept.Reporting an incorrect value for the error degrees of freedom, which are equal to (n – 2).When reporting F, neglecting to give the numerator degrees of freedom.Reporting r2 rather the r. Either would have been acceptable if I had not specifically requested r.After having made that error, reporting a 95% confidence interval for 2 – to be consistent with the F test (with = .05), a 90% confidence interval should be employed.Failing to put a blank space on each side of equality and inequality signs.Failing to indent the first line of each paragraph, an error which was noted in the feedback I provided following previous assignments.Neglecting to put statistical symbols (not Greek) in italic font.Neglecting to put a blank space after every comma.Neglecting to put a blank space on each side of any equality or inequality sign. TIP: Toggle on the display of formatting characters – in that way you can easily see where blank spaces are.Using a font size other than 12 point. The APA specifies 12 point font.Neglecting to draw the regression line on the scatter plot.Neglecting to delete the NOTES tables from the SPSS output.Using “data” as a singular noun. The APA insists it is pluralUse of the royal “we.”Not correctly producing the symbol for rho ().Creating the rho symbolMove to the Insert tab on the ribbon.Click Symbol.Select .Click Insert. ................
