Split-Half Method

The step to do split-half reliability


Then, to find the correlation (relationship between 2 variables), we should plot a graph of the results of the two halves. The graph can plotted by using Microsoft Excel. The best graph, which mean the best correlation between two results, is when the gradient of the graph is equal to 1. If the gradient is equal to 1, it means that the questions for two halves is at the same level as their knowledge. The reliability that can be accepted is when the gradient is 0.7 till 1.0, below 0.7 the reliability is not accepted.
