Possibilities to compare vibration in drilling rocks

Within the research, quality of control drilling vibrations for drilling of rocks was recorded. Prior to the determination research, it is necessary to verify hypotheses about the data, which states that data are from the same population for each type of rock. The paper deals with the possibilities of solving tasks with regard to the nature of the data measured. the R statistic software was used. The paper presents the algorithm and the verification results for four types of rock.
