An item is a single research screen of iCode™ survey where the Response Time is being measured – it consists of an attribute (a statement) and usually a stimulus (e.g. a brand, product design, etc.), but it might consist of a statement only. To calculate the number of items in the survey, multiply the number of tested elements (e.g. brands) by the number of statements/attributes that describe the tested element. If there is no stimulus tested, then the number of items is equal to the number of statements.
For example 1 element (e.g. brand) tested for 1 statement (e.g. high quality) is 1 item,
1 element x 10 statements = 10 items,
2 elements x 5 statements = 10 items,
3 elements x 10 statements = 30 items.
You can also see the number of items, the price and the estimated duration of the survey at the Summary section.
The maximum number of ITEMs in one study is 60. It allows you to keep the study relatively short and is comfortable for respondents.
