In this paper, we present the results of a functional software size measurement experiment. We have conducted this experiment to analyze variances in functional software size measurement results among individuals. We aimed to isolate the factors that cause these variances. At the end of the study, statistical results are displayed. Common measurement problems were presented including their causes. And finally factors leading to discrepancies were identified based on these findings.
