Abstract

The research aims to define skewness to know the type of skewness, by applying skewness measures such as the Karl-Pearson measure in its cases (median, median and moments) and Kelly’s measure and Bowly’s measure on real data for the variable (x, y), where the variable (x) represents the data for cement expansion taken from Badoush Cement Plant n=80 for the period (2008-2010) (Al-Sarraf, 2021) and the variable (y) represents data showing the times of failure resulting from various reasons for the life test device for n=30 devices (ZEENALABIDEN, 2023) .The Z-criterion was used to measure skewness for the data of variable X and for the data of variable Y. The results for both variables were outside the acceptable period for this criterion (1.96, -1.96).
