Final answer:
In a 2^k Design, each factor has 2 levels.
Step-by-step explanation:
In a 2^k Design, each factor has 2 levels.
Let's break down the question to understand it better. A 2^k Design is a method used in experimental design to analyze factors and their levels. The number 2^k represents the number of factors and their corresponding levels.
For example, in a 2^3 Design, we have 3 factors, and each factor has 2 levels, resulting in a total of 8 possible combinations or treatments.
