It is possible to group data in a numeric question according to the data found in that question. To do so, locate the question in the rows, columns or edges tab, then right-click it and select numeric, then the appropriate grouping method, as described below.
The available grouping methods are as follows:
Insert interval: allows you to create custom intervals for numeric questions. The response properties window appears with a default value of 0 that can, however, be modified, as follows:
In the interval section, select interval.
In from, enter the minimum boundary value. Then select incl if you wish to include this value within the interval; otherwise, it will be excluded.
In to, enter the maximum boundary value. Again, select incl if you wish to include this value within the interval; otherwise, it will be excluded.
Note: If you do not insert a maximum boundary value, askiaanalyse will take all values into account from the minimum boundary value (i.e. 'X' and over). Similarly, if you don't insert a minimum boundary value, askiaanalyse will take into account all values below that of the maximum boundary (i.e. 'Y' and under).
Find all values: AskiaAnalyse will automatically create a distribution of all existing values found in the numeric question.
Find 2 intervals: Creates two intervals around the median.
Find 3 intervals: Creates three intervals in order to assign 33.33% of the respondents to each interval.
Find 4 intervals: Creates four intervals in order to assign 25% of the respondents to each interval.
Find 'n' intervals: Creates 'n' intervals in order to assign 100/'n'% of the respondents to each interval (a window will prompt you to select the precise number of intervals you wish to create).
Create bands: Creates a specific number of evenly-spaced intervals in the data. Examples, assuming the data contains values from 1 to 100:
If you specify 5, then five evenly-spaced bands will be created (these bands would be 1-20, 21-40, 41-60, 61, 80 and 81-100).
If you specify 100, then the data would be split into 100 bands (i.e. 1, 2, 3, 4, etc., up to 100).
In start and end, you can specify the low and high values that will be used to calculate the bands (in our examples above, these would be 1 and 100). To specify values here, you need to uncheck automatically. If you leave detect automatically checked, then askianalyse will choose the start and/or end values, based on the lowest and highest values found in the data.
