# Create New Variables - Bottom 2 Category Variable(s) (Bottom 2 Boxes)

Create new variable(s) that show the proportion of respondents who selected the bottom 2 options

This tool creates new variables that show the proportion of respondents who selected the bottom 2 options in Pick One and Pick One - Multi questionsNominal, Nominal - Multi, Ordinal, or Ordinal - Multi variable sets (i.e., it computes what is commonly referred to as 'Bottom 2 Box' percentages). Categories which look like Don't Know options will not be included in the bottom boxes, and when such categories are identified the script will give you the option to remove them.

The bottom options are identified by looking at the numeric Value for each category that is not selected as Missing DataExclude from analyses in the ValuesDATA VALUES, and choosing the lowest.

## Usage

1. Select this option from Automation > Online Library.
2. Choose whether you want Q to automaticaly identify scale questions for you (for example, 5-point agreement scales), or if you just want to choose from all available questions.
3. Select the questions you wish to generate bottom boxes for.
4. If any of the selected questions look to contain Don't Know style answers, choose whether to include or exclude these options from the top boxes. Excluding them is equivalent to setting the category as Missing Data.
1. Select one or more variable sets under Data Sets.
2. Select Anything > Data > Variables > New > Ready-Made New Variables > Bottom 2 Category Variable(s) (Bottom 2 Boxes).
3. If any of the selected variable sets look to contain Don't Know style answers, choose whether to include or exclude these options from the top boxes. Excluding them is equivalent to setting the category as Exclude from analyses in DATA VALUES.

## Example

The table on the left shows a SUMMARY table of a Pick One - Multi questionNominal - Multi variable set. The table on the right shows a SUMMARY of the Pick Any questionBinary - Multi variable set created by this QScript. Note that the computation is performed prior to rounding, which is why the calculation does not appear to add up correctly.
