Warning: Sawtooth Software considers Choice-Based Conjoint and Adaptive Choice-Based Conjoint as the preferred techniques for measuring price sensitivity. Please use the Price Laddering approach with caution.
Description
Respondents answer a series of pricing questions. The question completes once the highest price the respondent is willing to pay has been determined.
Instructions
- Requires Better Lighthouse Library.
- Header 1 has two possible question texts, the former for a five-point Price Laddering question and the latter for a yes-no Price Laddering question.
- Line 3 of the HTML defines the prices to be offered to respondents, from least to greatest.
- The variables "_DynamicPriceX," "_DynamicResponseX," and "_FixedResponseX" should be duplicated so that one of each variable exists for each price on line 3.
Options
- The first price a respondent sees is determined by line 4 of the HTML:
my $start = 4;- Respondents start on the fourth lowest price.my $start = 'middle';- Respondents start on the middlemost price.my $start = 'random';- Respondents start on a random price.
- The acceptable and unacceptable response options are defined on lines 5 and 6 of the HTML. It is standard to either include two acceptable responses and three unacceptable responses (default), or one acceptable response and one unacceptable response ("Yes" and "No").
- Line 7 defines how the question selects the next price to display.
1will display the next adjacent price;2will display a random valid price. - Whether the question should require a response can be set on line 8. The error message to display if not responded to can be set on line 9.
