The Interviewer application allows several different types of questions: numeric, text, single-select categorical, multi-select categorical, list, date, GPS, barcode, and picture. As an interviewer, you must know how to answer each of them. To help you with that text, each question type is briefly explained below with visual aids.

Numeric

Questions that take a numeric response have a field for an open numeric answer. When that field is tapped, the numeric keyboard appears so that the interviewer can compose an appropriate numerical response.

Text

Text questions have a field for an open text response. When that field is tapped, the text keyboard appears so that the interviewer can compose an appropriate text response.

Categorical: Single-Select

Single-select categorical questions have answer options with radio buttons. To answer this type of question, the interviewer taps the radio button associated with the most appropriate answer.

Categorical: Multi-Select Multi-select categorical questions have answer options with check boxes. To answer this type of question, the interviewer taps in all appropriate check boxes. Selected answers will show a check in the box.

Categorical: Multi-Select in Yes/No Mode

Multi-select categorical questions in yes/no mode have two radio buttons for each item–one that denotes “yes” and another that denotes “no”. To answer this type of question, the interviewer taps the radio button associated with the most appropriate answer for each item.

Categorical: Cascading Selections
When unanswered, cascading selections look similar to text or numeric questions. Each question has a field where an answer can be composed. However, to answer these questions, the enumerator first taps in the field and then selects the most appropriate categorical answer from a drop-down menu. Selecting an answer option can be done either through tapping an option directly or through typing to narrow down answer options and then select the most appropriate.
 

List

Tap on the empty text box and use the keyboard to input an answer. Additional, elements can be added to the list until the maximum allowable number of items is reached.

To delete elements from the list, click on the X mark. However, be careful: doing so may result in deleting data, if the elements of a list question are linked to a roster (e.g., names of household members, each of which has their own row in the household demographics roster).

Date

First, tap on the enter date textbox.

Then, use the pop-up window to input the correct date. Depending on which is more convenient, the interviewer may either scroll elements of the date up and down (i.e., use the left-hand component of the date input in the image below) or pick the date from the calendar (i.e., use the right-hand component of the date input dialog).

After clicking the Done button, the date will be recorded. The recorded answer will be displayed below the question text, as pictured above.

Date: Current Time

Tap on the Tap to record current time box.

Then, the current time on the tablet will automatically be recorded.

GPS

First, tap on the textbox. This will open a window informing you that the tablet is searching for the GPS location. Closing this window will stop the tablet from searching for GPS.

Then, the tablet automatically records the GPS coordinates. The GPS location is displayed immediately below the question text, showing the longitude, latitude, accuracy, and altitude.

If GPS reading is not accurate enough, you may tap on the record GPS textbox again. Doing so will replace the old GPS reading with the new GPS reading. You can continue in this fashion until you obtain and adequately precise GPS reading.

Barcode

First, tap on the textbox.

Then, point the tablet’s camera towards the barcode, trying to align the red bars with the barcode, as above. 

Once the tablet can clearly read the barcode, the camera will turn off and the barcode’s value will appear just below the question text.

Picture

First, tap on the take a photo textbox. Then, point the tablet’s camera to compose your picture, pressing the camera icon on screen to take the picture.

Once the picture has been taken, press the check button to accept the picture or the X button, as pictured above, to reject the picture and replace it with another picture.

Then, the picture will appear below the question text. Tap on the take a photo textbox to replace the photo by retaking the picture.
