MAXQDA Stats supports the creation of a scale, consisting of several items. Before you start building a scale, it may be helpful to check the items for consistent polarity, otherwise the computation may give incorrect results. You can use the function Transform > Recode into other variable to standardize the item polarity.
To build a scale in MAXQDA Stats, select the function Scale > Reliability (Cronbach’s Alpha) from the main menu. A dialog will appear in which you can select all the variables you want to include in the initial scale.
Variables can be selected in several ways:
- Double-click on a variable.
- Drag and drop the variable into the right window pane.
- Select one or multiple variables with the mouse by holding the Ctrl/Cmd key then dragging the selection into the right window pane with the mouse, or click the blue arrow in the middle of the window.
To integrate code frequencies per document into the calculations, switch to the “Codes” tab and select the desired codes. (This option is available only if MAXQDA Stats was launched with the data of a MAXQDA project).
