A 2k factorial design is an experimental setup used in statistics to evaluate the effects of k factors, each at two levels (commonly labeled as low and high). This design allows researchers to systematically study the interactions between factors by running a full set of experiments at all combinations of factor levels, resulting in 2^k total experimental runs. It is particularly useful for identifying the optimal conditions and understanding how variables interact in multifactorial experiments. The simplicity and comprehensive nature of this design make it a popular choice in various fields, including agriculture, manufacturing, and product testing.

factorial of -1
Factorial 6 = 720
In Prolog, a simple factorial program can be defined using recursion. Here's a basic implementation: factorial(0, 1). % Base case: factorial of 0 is 1 factorial(N, Result) :- N > 0, N1 is N - 1, factorial(N1, Result1), Result is N * Result1. % Recursive case You can query the factorial of a number by calling factorial(N, Result). where N is the number you want to compute the factorial for.
