Home Energy Analysis (HEA) - Questions and Answers

The number of responses given to each answer in the HEA survey. This can refer to the number of responses for radio, checkbox, or drop-down questions, or for user-provided answers to ordinal questions.

Ordinal questions are questions where an integer is collected. For example, one of the questions in the survey is, "How often do you use your clothes washer?" In reply, customers can choose from among one of several ordinal answers: Less than once a week, 1-2 loads / week, 3-4 loads / week, and so on. The ordinal answer value in Opower Analytics Visualization refers to the number of customers who select one of those answers.

Another example of an ordinal question is the question about the customer's home size. In response, customers can enter an integer to represent the size of their home.

Type: Attribute

The abbreviated form of the survey answer. For example, DVD_PLAYER is used to represent the answer "DVD Player" in response to the survey question about what electronics a customer has in their home.

Sometimes the data in the Answer Bucket will be the same as in the Answer attribute above. However, this attribute will show aggregated data for ordinal answers.
