Note: the solutions to most of the multiple choice questions in these sections use what call the standard assignment of truth values to atomic propositions. The standard assignment of truth values assigns the values given here to the variables in the wffs in the exercises, when read left to right. So, the first variable in the formula read left to right gets the α assignment; the second variable in the formula read left to right (if any) gets the β assignment; the third variable in the formula read left to right (if any) gets the γ assignment; and the fourth variable in the formula read left to right (if any) gets the δ assignment.
For exercises with only one propositional variable, the standard assignment is:
For exercises with two propositional variables, the standard assignment is:
For exercises with three propositional variables, the standard assignment is:
For exercises with four propositional variables, the standard assignment is:
For each of the given propositions, determine which of the given sequences properly describes the column under the main operator, given the standard assignment of truth values to atomic propositions.
-(?C ? ?D) ? [D ? (C ? D) ]
Degrees Of Freedom
The number of independent values or quantities that can vary in the analysis without breaking any constraints.
Obtained Value
The actual value measured or calculated from a statistical test, which is compared against the critical value to draw conclusions.
Test Computation
The process of calculating results from test data, often using statistical methods to analyze the data.
Test Statistic
A value calculated from sample data during a hypothesis test that is used to determine the probability of observing the given or more extreme data if the null hypothesis is true.
