Prediction accuracy of time series and regression analyses can be important. Sometimes, however, we want to know only extents of a rise or fall using rough information. In this case, we want to get predictions easily. The models were tested to see if they could easily predict scale of variation using qualitative data. In this trial, the expected results were obtained. Therefore, this paper reports its prediction methods and results.
