Calculate Mean: Calculate the mean for each group. $\newline$ Boys: $(9 + 7 + 5 + 10 + 9) / 5 = 8$ $\newline$ Girls: $(6 + 5 + 7 + 3 + 4) / 5 = 5$
Calculate Variance: Calculate the variance for each group. $\newline$ Boys: $[(9-8)^2 + (7-8)^2 + (5-8)^2 + (10-8)^2 + (9-8)^2] / 4 = 4.5$ $\newline$ Girls: $[(6-5)^2 + (5-5)^2 + (7-5)^2 + (3-5)^2 + (4-5)^2] / 4 = 2.5$
Calculate Standard Error: Calculate the standard error of the difference between the means. $SE = \sqrt{(\frac{4.5}{5}) + (\frac{2.5}{5})} = \sqrt{1.4} = 1.183$
Calculate t-value: Calculate the t-value. $\newline$ $t = \frac{8 - 5}{1.183} = 2.534$
