Do hypothesis test using ANOVA to find if significant difference. Use alpha .05. All hypothesis steps and find degrees of freedom and critical values, calulate test statistic and effect size and write results in apa style.

Use Scheffe posttest if appropriate.

If you really want an expert to help you, be sure to follow directions and type your __subject__ in the **School Subject** box. Any other words, __including obscure abbreviations__, are likely to delay responses from a teacher who knows that subject well.
