+Before open the dialog, ensure you have created and selected a GLM which you would like to create an SPM on. There are currently 4 statistical tests to create an SPM with:
-  * Two-Sample T-Test: The standard students two-sample t-test.
+  * **One-Sample T-Test**: The standard students one-sample t-test. Tests that the value is non-zero.
+  * **Two-Sample T-Test**: The standard students two-sample t-test. Tests that the two samples are equivalent.
+  * **Paired T-Test**: The standard students paired t-test. Tests that all pairs of data are equivalent. Equivalent to a one-sample t-test of the paired differences.
+  * **ANOVA**: The standard ANOVA test. Tests that multiple groups are equivalent.
+==== Dialog Sections ====
 The dialog has 6 sections:
   * **SPM Name**: Enter the name for your SPM . Allows you to cycle through and select different SPM's. Must be a distinct name within the GLM.
-  * **Statistic**: Select the statistic to create a SPM for.
+  * **Statistic**: The statistic that we are testing for. Locked to that of the GLM.
-  * **Group 1**: Select the grouping for the first comparison for the t-test. Auto-populated with the groupings for the GLM, whether it is by group or workspace.
+  * **Group 1**(If relevant): Select the grouping for the first comparison (ex. for one-sample t-test). Auto-populated with the groupings for the GLM, whether it is by group or workspace.
-  * **Group 2**: Select the grouping for the second comparison for the t-test. Auto-populated with the groupings for the GLM, whether it is by group or workspace.
+  * **Group 2**(If relevant): Select the grouping for the second comparison (ex. for two-sample t-test). Auto-populated with the groupings for the GLM, whether it is by group or workspace.
+  * **Threshold **: The alpha value to threshold the test against.
+  * **Two-Tailed**: If the inference should be two-tailed.
   * **Cancel**: Cancels the process of creating a SPM.
-  * **Create SPM**: Creates a SPM. Makes this the "active" SPM, and populates the [[Sift:Application:Analyse_Page#Statistical_Parametric_Mapping|Visualization]]
