B Factor: The independent variable. The categories or groups of the independent variable will define which samples will be compared. When the initial F test indicates that significant differences exist between group means, contrasts are useful for determining which specific means are significantly different when you have specific hypotheses that you wish to test.

Contrasts are decided before analyzing the data i. Contrasts break down the variance into component parts.

They may involve using weights, non-orthogonal comparisons, standard contrasts, and polynomial contrasts trend analysis. Many online and print resources detail the distinctions among these options and will help users select appropriate contrasts. D Post Hoc: Optional Request post hoc also known as multiple comparisons tests.

Specific post hoc tests can be selected by checking the associated boxes. For detailed information about the specific comparison methods, click the Help button in this window. Alternatively, a directional, one-sided hypothesis test can be specified if you choose to use a Dunnett post hoc test.

Click the box next to Dunnett and then specify whether the Control Category is the Last or First group, numerically, of your grouping variable. By default, significance is set to 0.

When the initial F test indicates that significant differences exist between group means, post hoc tests are useful for determining which specific means are significantly different when you do not have specific hypotheses that you wish to test. Post hoc tests compare each pair of means like t-tests , but unlike t-tests, they correct the significance estimate to account for the multiple comparisons. E Options: Clicking Options will produce a window where you can specify which Statistics to include in the output Descriptive, Fixed and random effects, Homogeneity of variance test, Brown-Forsythe, Welch , whether to include a Means plot , and how the analysis will address Missing Values i.

Click Continue when you are finished making specifications. Let's use ANOVA to test if there is a statistically significant difference in sprint time with respect to smoking status. Sprint time will serve as the dependent variable, and smoking status will act as the independent variable. Just like we did with the paired t test and the independent samples t test, we'll want to look at descriptive statistics and graphs to get picture of the data before we run any inferential statistics.

The sprint times are a continuous measure of time to sprint a given distance in seconds. This is because Compare Means and additionally, the one-way ANOVA procedure itself requires there to be nonmissing values for both the sprint time and the smoking indicator. Lastly, we'll also want to look at a comparative boxplot to get an idea of the distribution of the data with respect to the groups:. From the boxplots, we see that there are no outliers; that the distributions are roughly symmetric; and that the center of the distributions don't appear to be hugely different.

The median sprint time for the nonsmokers is slightly faster than the median sprint time of the past and current smokers. The Means plot is a visual representation of what we saw in the Compare Means output. The points on the chart are the average of each group. It's much easier to see from this graph that the current smokers had the slowest mean sprint time, while the nonsmokers had the fastest mean sprint time. To determine that, we would need to follow up with multiple comparisons or post-hoc tests.

Search this Guide Search. Data Requirements Your data must meet the following requirements: Dependent variable that is continuous i. This means that: subjects in the first group cannot also be in the second group no subject in either group can influence subjects in the other group no group can influence the other group Random sample of data from the population Normal distribution approximately of the dependent variable for each group i.

These conditions warrant using alternative statistics that do not assume equal variances among populations, such as the Browne-Forsythe or Welch statistics available via Options in the One-Way ANOVA dialog box.

When this assumption is violated, regardless of whether the group sample sizes are fairly equal, the results may not be trustworthy for post hoc tests.

When variances are unequal, post hoc tests that do not assume equal variances should be used e. Researchers often follow several rules of thumb for one-way ANOVA: Each group should have at least 6 subjects ideally more; inferences for the population will be more tenuous with too few subjects Balanced designs i.

Data Set-Up Your data should include at least two variables represented in columns that will be used in the analysis. Note: SPSS restricts categorical indicators to numeric or short string values only. Please check your Junk E-mail folder just in case the email was delivered there instead of your inbox.
