Which t-test should be used to analyze whether sex predicts number of speeding tickets? (single sample, repeated measures/within subjects, or independent samples/between subjects) State the independent variable (IV). State the dependent variable (DV). State the Null hypothesis (H0): Run your t-test (see the SPSS guide at the bottom of the document for instructions). How many speeding tickets did males and females get on average? X males = X females = Next, type your results in APA format (t(df)=x.xx, p=.xx, d=.xx): (Note, use the "Two-sided p" for your p-value in the Equal variances assumed row) Explain what your results mean. If you reject the null, be sure to include the direction of the result, i.e., explain which sex generally speeds more. Mention whether you have a small, medium, or large effect size (d .2 or -.2 small; d .5 or -.5 medium; d .8 or -.8 large). Finally, use Excel to make a graph of your two group means (See instructions at the bottom of this document, and/or my lab tutorial)
