    Text data is highly voluminous and performing mining tasks on it can be daunting due to large memory usage, thus researchers have considered different techniques to reduce the data while still maintaining or increasing the level of accuracy. Stop word removal is one of the pre-processing techniques used in text data mining. This paper investigates the effect of stop words removal on the text data mining performance. The machine learning algorithms used are C4.5 Decision Tree and Multinomial Naïve Bayes (MNB) on two text datasets; Sentiment Analysis and SMS Spam dataset. Results revealed that the removal of stop words had no influence on the classification accuracy of text mining model, but actually reduced the level of confidence of the prediction
