Researchers use multiple methods for data checking. Each method can help identify and fix errors that were introduced during the data entry process. Fixing the errors that were introduced during the data entry process increases the accuracy of the research results. Accuracy is important because if a researcher publishes inaccurate results other researchers would not be able to replicate those results and draw the same conclusions. The purpose of this study is to compare the accuracy of four different data checking methods: double entry with one person, double entry with two people, visual checking, and solo read aloud. So far, previous research has shown that double entry is more accurate than visual checking (Barchard & Pace, 2011) and partner read aloud (Kawado, Hinotsu, Matsuyama, Yamaguchi, Hashimoto, & Ohashi, 2003). Although there has not been many studies done on the comparison of these four methods and only one study has used solo read aloud, double entry has been shown to produce the highest quality data. I therefore hypothesize that the two double entry methods will have the highest accuracy.
