Recall that when you are writing up a results section you want to cover three things:
    a)    Tell the reader the analysis that was conducted.
    b)    Whether the analysis was significant including the appropriate statistical "proof."
    c)    Describe what the analysis means in words. Be sure to include means and 
           standard deviations either in the text or in a table.

Below you will find descriptive information and an analysis of variance summary table. This table is from an experiment that investigated whether physically attractive vs. unattractive defendants in a criminal case would be rated differently on amount of guilt (GUILTY) and length of prison sentence (PRISON). Because there is only one independent variable (attractiveness of the defendant), this analysis is referred to as a one-way analysis of variance. If there were two independent variables, then the analysis would be referred to as two-way analysis of variance.

A good results section for the analysis on guilt ratings would be:

        An alpha level of .05 was used for all statistical tests and r was calculated as the effect size (Rosenthal, 1991).

Guilt Ratings (tells the reader what the paragraph will be about).

        A one-way analysis of variance (ANOVA) was calculated on participants' ratings of 

defendant guilt. The analysis was not significant, F(1, 37) = 1.20, p > .05 (r = .18).

Participants who read about an unattractive defendant rated the defendant more guilty (M = 6.50, 

SD = 1.85) than participants who read about an attractive defendant (M = 5.79, SD = 2.20).

Try writing the results for the analysis on length of prison sentence ratings...I'll get you started.

Length of Prison Sentence Ratings

        A one-way ANOVA was calculated on participants' ratings of length of prison sentence for 

the defendant. The analysis was significant, F(  ,    ) =          , p       .05 (r =       ).

What goes in the "F (   ,     )"?

The information contained in the "F(   ,     )" can be most easily found in the analysis of variance summary table under the "df" column. This information is the degrees of freedom (df) for your experiment. Specifically, the degrees of freedom in the numerator (between groups) and the degrees of freedom in the denominator (within groups or error). The first number is your between groups degrees of freedom followed by your within groups degrees of freedom. Because your degrees of freedom are dependent on the number of participants you have in each of your conditions, your degrees of freedom may change from analysis to analysis.

What comes after the "="?

The information that comes after the "=" is the actual value of that F. This value can be found in the analysis of variance summary table under the "F" column.

How Do I Know if the Analysis is Significant?

Simple. All you need to do to determine whether that particular analysis is significant is to, again, look at the analysis of variance summary table under the "Sig." column. The "Sig." column is your probability level for that particular analysis. Remember, any value in this column that is LESS than .05 is significant. All other values in that column that are greater than 
.05 are NOT significant. But, I KNOW you remember all of this from your statistics class...right?

What is "r"?

"r" is an effect size. There is a very simple formula for calculating r. You can find the formula for r and more information on effect sizes by following this link or the "(r = .18)" link above under the "Guilt Ratings" heading.

One-Way Analysis of Variance with Three Groups

Below you will find descriptive information and an analysis of variance summary table. This table is from an experiment that investigated whether the type of music that song lyrics were attributed to would differently impact whether participants 
thought the lyrics were objectionable (OBJECT) and whether they thought the lyrics should have a mandatory warning label
(WARN). This analysis differs from the one above, because the independent variable (type of music) has three levels. When
you have an independent variable that has three or more levels, then you must run comparisons among the levels (e.g.,
country vs. rap, country vs. heavy metal, rap vs. heavy metal) for each of the dependent variables.

        An alpha level of .05 was used for all statistical tests and r was calculated as the effect size (Rosenthal, 1991).

Objection to the Lyrics

        A one-way analysis of variance (ANOVA) was calculated on participants' ratings of 

objection to the lyrics. The analysis was significant, F(2, 61) = 5.33, p < .05. Participants

found the lyrics more objectionable when they were attributed to rap music (M = 6.25, 

SD = 2.71) than when the lyrics were attributed to heavy metal (M = 5.10, SD = 0.63)

or country music (M = 3.91, SD = 2.92). Comparisons indicated that the rap music condition

was significantly different from the country music condition , t(61) = -3.26, p < .05, r = .39. 

The rap music condition was not significantly different from the heavy metal condition, t(61) = 

1.58, p > .05, r = .20. The country music condition was not significantly different from the

heavy metal music condition, t(61) = -1.67, p > .05, r = .21.
