This post will cover how to add the number of times a certain response has been given for a variable (its frequency or count), and append this information to the data set as a new variable in SPSS. For example, say you have a list of names. Next to each name you’d like to add the number of times the name appears in the list. In SPSS, this information is easy to view with the “frequencies” dialogue, but how do you add it as a variable automatically?
Doing Math in Qualtrics
Sometimes when creating surveys in Qualtrics you wish to do some kind of math on a respondent’s answer. This post outlines a simple way to do so using javascript.
The procedure involves three main components. First, there are the questions themselves. These are the responses you wish to do some math operations on. Second, there are embedded data variables. You create these variables in the survey flow, and they allow you to save the values you calculate for later use. For example, you could use them in the survey flow (branch logic) or display the values as piped text. Third, there is the javascript. The javascript reads the answers of the questions, performs the math, and saves the embedded data variables.

Implicit vs Explicit Targeting
Scott Galloway seems to claim that implicit targeting based on clickstream (i.e. observing a user’s browsing history and making recommendations) beats self-reports by a wide margin. While I’ve said before that I think doing so is a great idea, I’m not sure this will always be true. Google has done quite well for itself by demanding that users first type something into the search box.

Life is full of problems that are, quite simply, hard. And the mistakes made by people often say more about the intrinsic difficulties of the problem than about the intrinsic fallibility of human brains. – Brian Christian & Tom Griffiths

Sorting As Screening – Poster Presented at SCP 2016 St. Pete

Abstract
Sorting by a product attribute can diminish the importance weight of that attribute. When choosing is difficult, consumers may treat sorting as screening. Once options are sorted, consumers may form a consideration set comprising the options at the top. Because these options are more homogeneous with respect to the sorted attribute, consumers pay less attention to the sorted attribute in favor of a second attribute. This attentional shift emerges in a subsequent conjoint analysis, with less weight placed on the sorted attribute and more weight on a second attribute.
