In this question, you will do some power calculations. This is often a question of whether or not your sample size is large enough to detect an effect. This is a calculation that determines if you will have enough power to detect an effect with a test of size a. Power Calculation - in most statistical experiments, it is expected that the researchers complete a power calculation.

Determination of corneal elasticity coefficient using the ORA database. It is rightly assumed that the active plan of experiments represents a possible optimal planĪvetisov, S. It is meant to choose the most suitable mathematical model, but which requires a minimum number of experiments. Which would exceed the value of the positive effects that will result from their results. Required to be optimized, because it does not make sense to make a very large number of experiments, the value of To current knowledge, is proportional to the square of the number of experts participating in them, while theirĮfficiency is proportional to the square root of the total number of experiments. The cost of experimental research, according Also, in this case a large number of experiments would have toīe performed, but the reliability of the results would be at a low level. Others remained at the initial level, is practically not used in contemporary industrial facilities, because this methodĭoes not take into account the interactions of factors. The classical approach to conducting an active experiment, when only one factor (variable) changed, while the Selection phase in the final stage for the correct interpretation of data and results. This can beĭecomposed in advance into the following notions: during the analysis of the relevant notes before and during theĮxperiment planning during the processing of the results arising from the experiment in the research strategy This means that specific mathematical methods must be used at all stages of the experiment. Used here, means laying out experiments based on a scheme previously designed in the form of the respective Of processing these results (collected data), are put into service in the last stage of an important process towards theįormation of the mathematical model for the object under consideration. Modeling, supported the processing of results from the 'passive experiment'. Statistical methods (regression analysis, statistical correlation, etc.), which were mainly used for mathematical The 70s, and their rapid development and application is being encouraged by the intensive use of computers. The mathematical theories concerning the plan of experimentation are relatively new.
