The formula for calculating the average is based on the manipulation of the cells, in the form =C2/B2. As the spreadsheet is unaware of the user's desire for D to be an ...
P-Values: The p-value is a measure of the probability that the observed data would occur by chance if the null hypothesis were true. In replication studies p-values help us determine whether the findings can be consistently replicated. A low p-value in a replication study indicates that the results are not likely due to random chance. [6]
As objects are made up of several different parts, copying becomes nontrivial. Several strategies exist to treat this problem. Consider an object A, which contains fields x i (more concretely, consider if A is a string and x i is an array of its characters). There are different strategies for making a copy of A, referred to as shallow copy and ...

If the values of all variables in a propositional formula are given, it determines a unique truth value. A propositional formula may also be called a propositional expression, a sentence, [1] or a sentential formula.
