In card view, each variable appears on a Variable card. The variable card displays a top-line summary of the data contained in that variable.
Hover your mouse cursor over a variable to reveal the Properties link below the card – click this link to reveal Variable Properties for that variable. Note that if you cannot edit the dataset, these properties will be read-only.
The following variable types are currently supported by Crunch.
A categorical variable represents a question for which the respondent could choose exactly one answer. Click Valid/Missing at the bottom of the card to show missing values and reasons.
A multiple response variable represents a question for which the respondent could choose any number of responses, i.e. “choose all that apply.” As with categorical variables you can click the Valid/Missing area to show missing values and reasons.
Each category of a multiple response variable is represented by a dichotomous subvariable (i.e. each subvariable describes whether the variable is selected or unselected for the corresponding category). See Analyzing Data for more information about using subvariables in analyses.
A numeric variable represents a question to which the respondent gave a numeric answer. The variable card displays a histogram of the responses as well as summary statistics.
A date/time variable represents a timestamp, for example the date of a survey. The variable card displays a histogram of the dates in the variable.
A categorical array represents a series of questions with the same response options. The responses are shown in the columns while the individual questions are shown in the rows.
Valid/missing shows how many valid responses exist for any item (row) in the array, which is usually a range. In the example above, if a respondent was not asked about mobile internet usage because they did not have a mobile device, they would not be included in the “Mobile” row. “Missing (all)” indicates the number for which no valid category is selected for any of the items in the array.
Each row of an array is represented by a subvariable that contains each of the column categories. See Analyzing Data for more information about using subvariables in analyses.
Click Valid or Missing to see the number of missing values for each row.
