First, qualitative variables are specific attributes that are often non-numeric. Many of the examples given in the car example are qualitative. Other examples of qualitative variables in statistics are gender, eye color, or city of birth. Qualitative data is most often used to determine what perc...
by nature, they're not subject to governmental oversight; therefore, the economic activity does not generate tax returns or appear in official statistical reports; however, tracking outgoing expenditures, even though the transactions are cloaked, can give a sense of statistics. In other words, the ...
The central limit theorem states that the mean of a sufficiently large number of identically distributed random variates will be approximately normally distributed. Or in other words, the sampling distribution of the mean tends toward normality, regardless of the distribution. Distributions and Hypothesis...
In the 1960s, the social sciences became "critical," in other words, they gradually shifted from the kind of role summed up in Durkheim's slogan to an unveiling function: their purpose now was to unmask and denounce the true social relationships that lay behind an ideology. The critique of...
In other words, the location of the pendulum in a good region or bad region is unrelated to where it was a second before, and—here’s the rub—there isn’t even a pendulum. The fickle finger of fate pops randomly from possible outcome to possible outcome, and the probability of it ...
In other words, the intersection of A and B is the empty (or null) set, denoted by ∅, as depicted in Figure 6-5. To put the definition in plain English, disjoint events are events that have nothing in common with each other. Disjoint events are said to be mutually exclusive, and...
In other words, a peak that tends to the left is “left skewed.” This is incorrect. There are two main things that make a distribution skewed left: The mean is to the left of the peak. This is the main definition behind “skewness”, which is technically a measure of the ...
In other words, consumers do not want businesses to obtain data on them by purchasing it from third parties. Source: Segment 6. 83% of consumers are willing to share data with brands to receive personalized experiences Accenture surveyed 8,000 consumers from around the world to uncover key dat...
(yes, I know he was governor –see here). In other words, 60% of the people who die prematurely as a result of strokes, ischaemic heart diseases, chronic obstructive pulmonary diseases and lung cancers can be attributed to indoor air pollution. That means pollution resulting from the fact ...
In other words, scene complexity influenced the speed of information accumulation, resulting in higher reaction times and more errors for low and high complexity scenes. Experiment 2 A key question is whether the effects found in experiment 1 are driven by the two scene statistics together, as ...
