 # IDC-dominant-gene
-Statistical analysis to determine the dominant gene for Invasive Ductal Carcinoma (IDC).
+Invasive Ductal Carcinoma (IDC) is a type of ductal carcinoma which is one of the breast cancers that started in the milk duct of women’s breasts. 
+
+The two most common genes that cause IDC are TP53 and ERBB2. To determine which gene is the dominant one, statistical analysis is performed using R.
+The analysis carried out includes:
+- checking for outliers
+- normality of the genes
+- mean and median values
