Launch the Oneway Platform

To perform a one-way analysis of variance, do the following:

1. Select Analyze > Fit Y by X.

2. Enter a continuous column for Y, Response.

3. Enter a nominal or ordinal column for X, Factor.

Figure 6.4 The Fit Y by X Launch Window 

The word Oneway appears above the diagram, to indicate that you are performing a one-way analysis.

Note: You can also launch a one-way analysis from the JMP Starter window. Select View > JMP Starter > Basic > Oneway.

For more information about this launch window, see Introduction to Fit Y by X. For more information about the options in the Select Columns red triangle menu, see Column Filter Menu in Using JMP.

Specifying a Block variable identifies a second factor, which forms a two-way analysis without interaction. In the Oneway plot, the values of the Y variable are centered by the Block variable. If there are equal counts in each block by group cell, the available Oneway platform options are adapted to the two-way analysis setting. If there are unequal counts in the block by group cells, a Fit Model report is shown below the Oneway plot and the Oneway platform options are not available.
