There were too few subjects. First, people who say they have ESP don't always have it, and those who are randomly selected may have a tendency to perform well on ESP tests. We should also attempt to identify known or expected sources of variability in the experimental units since one of the main aims of a designed experiment is to reduce the effect of these sources of variability on the answers to questions of interest.

When you design an experiment, you are controlling and measuring variables. a small sample size to insure a reliable outcome of the experiment . In a well designed experiment, only one variable is changed? In design of experiments, single-subject design or single-case research design is a research design most often used in applied fields of psychology, education, and human behavior in which the subject serves as his/her own control, rather than using another individual/group. It is unlikely, for example, that a pilot study alone can provide adequate data on variability for a power analysis to estimate the number of animals to include in a well designed experiment. If other scientists get different results, then you have overlooked one or more important parts of your experimental design, like a variable you didn't take into account that influences the outcome. A well-designed and constructed experiment will be robust under questioning, and will focus criticism on conclusions, rather than potential experimental errors.A sound experimental design should follow the established scientific protocols and generate good statistical data.. As an example, experiments on an industrial scale can cost millions of dollars. Review Part A How many variables should there be in a well-designed experiment?
