Underfitting

Underfitting is when a data model is unable to capture the relationship between the input and output variables accurately, generating a high error rate on both the training set and unseen data. Underfitting occurs when a model is too simple, which can be a result of a model needing more training time, more input features, or less regularization. IBM. (2021). What is underfitting?

Unpaired t-test

An unpaired t-test is a statistical test comparing the averages/means of two independent or unrelated groups to determine if there is a significant difference between the two. Gleichmann, N.
