Marketing - Price Sensitivity Meter

Plot the Van Westendorp Price Sensitivity Meter to determine what price most people consider is reasonable

Plots the Van Westendorp Price Sensitivity Meter to determine what price most people consider is reasonable.

Inputs

DATA SOURCE

The input data can be supplied using either Paste or type data or existing output in 'Pages'. These are expected to be tables where each row is the response to 4 columns. The columns contain the response to the question: At what price would you consider this product/brand to be 1) Too cheap, 2) Cheap, 3) Expensive, 4) Too expensive.

Alternatively, if the survey responses are present as variables in the data set, the variables can be individually selected as Price considered 'Too cheap' , Price considered 'Cheap' , Price considered 'Expensive' , Price considered 'Too expensive' . If less than 4 of these variables are provided, then only the intersections of the variables provided will be shown.

Chart

Intersection Points

Show intersection labels Label the points where the curves meet, i.e. the point of marginal cheapness, optimal price point, indifference point price and the point of marginal expensiveness.

Number of decimals Number of decimals to show in the intersection labels.

Wrap intersection labels Whether the intersection labels should be wrapped; otherwise they will be shown in a single line of text which may be quite long.

Intersection labels width (in characters) This specifies when the line breaks are introduced into the labels. Line breaks are added at the closest wordbreak before the number of characters specified.

Arrow color The color of the arrow next to the intersection labels

Arrow line width Line width of the arrow (in pixels).

Arrow length Controls the length of the arrows (and therefore how close the labels are to the intersection points).

Currency symbol The currency symbol used in the labels. These will also be used as the defaults in the CATEGORIES (X) AXIS, however, there is a separate control in that group to specify a different symbol (or no symbol).

Refer to Visualization Options for general chart formatting options.
