ABSTRACT
The mode is the most common value that occurs in a set of discrete data. In the naming task data (see Table 2.1) the mode was 26 since this was the score that occurred most often. If there are two most common values which occur with equal (or almost equal) frequency in a distribution of discrete data, then there are two modes, and the distribution is called bimodal. For example, imagine that a new type of cola drink is tasted by a sample of 30 people, and everyone rates how much they like it on a five-point scale (1 = not at all, 3 = neutral, 5 = very much). The results are presented in Figure 2.4. The distribution of these data is bimodal since there are two ratings (i.e., 1 and 5) which are the most common and which were chosen by the same number of people (i.e., 9).
