Paper Tile :Imputing Missing Values for Data Samples In Educational Empirical Research Using Machine Learning Techniques

Authors : Ms.Pooja Manghirmalani Mishra and Ms.Rabiya Saboowala

Abstract

The major concern that arises in every research that involves physical data collection is the loss of data which happens because certain units of sample are rejected due to missing responses or values of the participants. The problem of missing values in the data is more profoundly seen where the amount of time spent by the participant in going through the test is in hours. For this study, data was collected from in-service teachers in order to understand their acceptance to adopting blended learning pedagogy as the new normal post Covid era. To solve the proposed problem, two methods are investigated for imputing the missing values; network prediction using multi-layered feedforward neural network model which predicts the missing value and multi-layered feed-backward neural network model which imputes missing values using estimated values from predictor networks, and their performance is compared. It has been found that the multiple-layered feedback neural network model was superior in terms of accuracy. When we combine the technology of machine learning with educational research problems, a lot of issues can be catered to, out of which, one of the common ones is of the missing values.
