CHAPTER 11 DATA SET 2 Gender: 1 - male, 2 - female Gender Hand Up Gender Hand Up Hypothesis [Ho: Research Hypothesis aka Alternative hypothesis (Ha: It Is a two talled test or one-talled? Significance level [a]: (Choose usually, It Is elther 0.01 or 0.05] Direction: Compute the following values: Sample statistics Description Computed Values Mean for group 1 Mean for group 2 Number Participants in group 1 Number participants in group 2 Variance for group 1 Variance for group 2 Now substitute the values obtained in the formula (formula of t-value). Continue solving until you get the value. X X, Degrees of freedom (show computation using n, +m,-2) JP TAR -2 "Now go to the attached table (F-cable). Using your computed degree of freedom (df) and the level of significance (a), find yo critical value to be compared with the t value. SUMMARY Computed t value Degree of freedom The critical value you got from the f-table (based on di and a] Now, compare your computed t value with the critical value. Is It smaller, larger or equal? Decision In sentence form, as to whether you will reject the null hypothesis or fall to reject It.)
