This means that if we roll a die 60 times we can expect each of the six faces to come up an equal amount of times, which would be 60 ∕ 6 = 10. Thereby we can say that as Dave is to roll a die 60 times, he should expect 10 of ...
WebbThe value found measured in the experiment referred to as the experimental value. The standard value is the value that is typically regarded as true by scientists and is also called the accepted value or theoretical value. “An error does not become a mistake until you refuse to correct it.” — John F. Kennedy Webb1.1 Expectancy-Value Theory. As formulated by Eccles and colleagues, expectancy-value theory holds that achievement-related choices—such as deciding to major in engineering with the goal of becoming a civil engineer—are governed by a variety of factors (Eccles, 1994; Eccles (Parsons) et al., 1983; Meece, Eccles-Parson, et al., 1982 ).
