Full Factorial Design Calculator

To create a Full Factorial design online, simply select the number of factors, the number of repetitions and the number of blocks. Now you can give the factors names and set the number of levels per factor. The Full Factorial Design generator will then output your experimental design.

The calculated full factorial design can then be exported to Excel and you can run the experiments. Once the experiments have been carried out, you can analyse them again with DATAtab. If you have to many factors, you can also use the Fractional Factorials Design calculator.

A Full Factorial Design is a comprehensive approach used in the field of experimental design or design of experiments (DoE). It's a methodological framework used to study the effect of multiple factors across multiple levels. Here are some key aspects of Full Factorial Design:

Key Aspects

  • Multiple Factors and Levels: In a full factorial design, experiments are conducted for all possible combinations of levels across all factors. For example, if there are two factors and each factor has three levels, the full factorial design would consist of 3 × 3 = 9 experiments.
  • Thorough Analysis: This approach allows for a complete analysis of the interaction effects between factors, in addition to their main effects. It provides a comprehensive understanding of how different factors influence the response variable and how they interact with each other.
  • Design Complexity: The number of experiments required increases exponentially with the addition of more factors or levels. For instance, with 3 factors each having 3 levels, the design would require 33 = 27 experiments.
  • Data Richness: Full factorial designs yield a rich data set that can be analyzed to understand the effects and interactions in great detail. This can be particularly valuable in settings where the relationships between variables are not well understood.
  • Versatility: This design is versatile and can be applied in various fields such as industrial engineering, product development, and scientific research, where understanding the complex interaction between variables is crucial.
  • Resource Intensiveness: Due to the large number of experiments required, full factorial designs can be resource-intensive in terms of time, materials, and costs, especially as the number of factors increases.
  • Statistical Analysis: The results from a full factorial design are typically analyzed using techniques such as ANOVA (Analysis of Variance), which helps in identifying significant factors and interactions.

Full Factorial Design is particularly useful when it's important to observe the interaction effects between factors, and when the resources are available to conduct the comprehensive set of experiments required. However, in cases where resources are limited, other experimental designs like fractional factorial designs may be more practical.

Full Factorial Designs are suitable for experiments with a small number of factors and levels. If you have more factors and want to determine nonlinear relationships, you can also use the Box-Behnken Design Calculator. Box-Behnken Design requires fewer experimental runs than Full Factorial Design for three or more factors, making it more practical for larger experiments. Alternatively, you can also use the Central composite design Calculator.
