Probably the commonest way to design an experiment in psychology is to divide the participants into two groups, the experimental group, and the control group, and then introduce a change to the experimental group and not the control group.
The p-value is widely used in statistical hypothesis testing, specifically in null hypothesis significance testing in this method, as part of experimental design , before performing the experiment, one first chooses a model (the null hypothesis ) and a threshold value for p , called the significance level of the test, traditionally 5% or 1%.

The design of experiments (doe, dox, or experimental design) is the design of any task that aims to describe or explain the variation of information under conditions that are hypothesized to reflect the variation. A test of a statistical hypothesis, where the region of rejection is on only one side of the sampling distribution, is called a one-tailed test for example, suppose the null hypothesis states that the mean is less than or equal to 10. Quasi-experimental designs in a quasi-experimental design, the researcher lacks control over the assignment to conditions and/or does not manipulate the causal variable of interest a quasi-independent variable is not manipulated by the researcher but rather is an event that occurred for.
