摘要：The study compared errors in slope committed by physics students using the manual method of graph plotting and Origin lab software. A descriptive survey design was adopted for the study. The study was carried out using 52 final year students (39 males & 13 females) from Physics and Astronomy department, University of Nigeria, Nsukka. Optics Practical Test (OPT) was used for data collection. Kendal Coefficient of Concordance (KCC) which yielded 0.85 reliability coefficient was used to obtain the reliability of the instrument. The mean and standard deviation of the computed errors were used to answer the research questions, while the t-test, was used to test the hypotheses at 0.05 level of significance. Findings showed that Origin lab software reduces error in slope than manual method among others. It was recommended that Origin lab computer software be adopted in plotting graphs for reduced errors in slope.
