In Chapter 2 we discussed how to summarize data using different methods and to display data using
graphs. Graphs are one important component of statistics; however it is also important to numerically
describe the main characteristics of a data set. The numerical summary measures, such as the ones
that identify the center and spread of a distribution, identify many important features of a distribution.
For example, the techniques learned in Chapter 2 can help us graph data on family incomes.
However, if we want to know the income of a “typical” family (given by the center of the distribution),
the spread of the distribution of incomes, or the relative position of a family with a particular income,
the numerical summary measures can provide more detailed information (see Figure 3.1). The
measures that we discuss in this chapter include measures of (1) central tendency, (2) dispersion
(or spread), and (3) position.
The type of logical fallacy that involves an argument based on the opinion of someone who is no an expert on the topic is Appealing to false authority.
Classical, soft pop and <em>certain types of folk music</em> are most likely to encourage relaxation. It determines to have the bulk of the musical components needed to <em>assist people in relaxing</em>, and further discussion can be defined as follows:
- It is a kind of sensory stimulation, that can be detected via our <em>sense modalities</em>, such as the eyes, feel, and ears.
- It's disputed when it works or not, but there is some evidence that it does.
- Another study contends that it is ineffective and should not be <em>utilized for ads</em>.
- Therefore, Subliminal stimulation is shown through <em>soothing musical CDs</em> that include <em><u>undetectable instructions</u></em> meant to encourage people to consume more vegetables and fruit.
Therefore, the final answer is "subliminal stimulation".
