Data analysis guide for Single Replicate Factorial Designs
1.0Introduction
This document intends to provide a quick guide to determine the factors/ interaction of factors that would have statistically significant effect on the output of interest. A simple way to do so is by constructing a normal probability plot of effects. Figure 1 is an example of such plot. Data points that fall along the straight line (black dots) correspond to factorial effects with negligible influence on the output; while outliers that deviate greatly from the line (red dots) are factors/ interaction of factors that have a significant effect on the output. Figure 1 illustrates that factors A,C,D, and the interaction between factors A and D, are primary factorial effects that influence the output.

2.0Experiment Design
The experiment of interest aims to evaluate the joint effects of four factors on injection molding products’ critical dimension. The four factors are listed in Table 1, with an alphabet assigned to each factor for easy referral in this report. AMold Temperature

BHolding Pressure
CInjection Rate
DCooling Time

Table1: Four factors under investigation
Single replicate Factorial design is chosen for the investigation as it provides the smallest number of runs for which k factors can be studied in a complete factorial design. With four factors of interest, each at two levels, an experimental measurement from each of treatment combinations are required for the analysis. Table 2 shows the setting of the four factors for all treatment combinations. Runs

* In statistics the group we wish to study is called the population
* A sample is a subset of the population which is used to gain insight about the population. Samples are used to represent a larger group, the population.
* • Descriptive statistics – the collection, organization, analysis, and presentation of data.
* Inferential statistics – uses descriptive statistics to estimate population parameters; an educated guess about the...

...ADVANTAGES OF THE FACTORIAL DESIGN
Some experiments are designed so that two or more treatments (independent variables) are explored simultaneously. Such experimental designs are referred to as factorial designs. In factorial designs, every level of each treatment is studied under the conditions of every level of all other treatments. Factorial designs can be arranged such that three,...

Independent variable
← One that influences the dependent variable in either a positive or negative way.
Example
← Cross-cultural research indicates that managerial values govern the power distance between superiors and subordinates.
Moderating variable
Has a strong contingent effect on the independent variable - dependent variable relationship.
← Modifies the original relationship between the...
