To improve prediction accuracy of a model. The present disclosure provides a model creation method executed by an information processing apparatus that creates a model to associate input data included in learning data with output data. The model creation method includes a first exclusion process of excluding the learning data in which the input data is an outlier, from a learning data set; a second exclusion process of excluding the learning data in which the input data and the output data are outliers, from the learning data set; a first model creation process of creating a first model using the learning data set from which the learning data is excluded in the first exclusion process; a second model creation process of creating a second model using the learning data set from which the learning data is excluded in the second exclusion process; and a model selection process of adopting the model having better prediction accuracy between the first model and the second model.
