Abstract EN

Homogeneity tests are used in linear regression to test the variance homogeneity hypothesis that requires conditions, requirements and hypotheses to be applied.

if one of these conditions is violated, we will obtain inaccurate results.

therefore, we resort to other methods that give reliable results in decision-making.

from this perspective, it is imperative for the researcher to test and examine the data and information to know the nature of the data and thus clarify the relationship between the various factors and analyze the results more accurately and more thoroughly, hence the importance of research in the use of statistical tests that test the hypothesis of variance homogeneity and detect whether the data has a problem of variance Heteroscedasticity or not, and the tests used in this study are spearman rank test, Coldfield Quandt test, Park test, Levene test and Bartlett test, the results were analyzed using the program SPSS Ver 20, MINITAB Ver 16 and its application to the relationship between money supply and its effects on the GDP in Iraq for the period (2005-2015).
