A tool that enables you to draw quantitative conclusions about a procedure or series of actions is a statistical test. The objective is to determine whether there is sufficient data to "reject" a theory or hypothesis regarding how the process functions. This concept is known as the null hypothesis. In addition to offering journal services, Baghdad Edit is a leader in the use of application of statistical tests in Baghdad Iraq. Not rejecting could be a desirable outcome if we want to behave as though we believe the null hypothesis is true. It could also be a disappointing result, indicating that we don't yet have enough data to rule out the null hypothesis and declare something to be prove.
