OTHER:

I am very determined and a hard worker. I am very much willing to learn from others. Have good communication skills and computer skills. I consider myself competent, reliable, and responsible. PROJECTS ACCOMPLISHED

The first project I was involved in is a research project in partial fulfilment of my BCom (Hons) degree. The research project involved me working as an individual under supervision. My topic was based on Repeated-Measures Designs, which is mostly associated with Behavioural sciences and meta- analysis. Repeated-Measures Designs involve measuring subjects more than once to determine statistically significant change over time. The designs can be effectively used in determining how effective certain medications are on certain people; or how effective rehabilitation is on certain people where the period variable is time. Statistical Analysis software such as SAS (Statistical Analysis Software), SPSS (Statistical Package for the Social Sciences) was used for analysis. The Second project I was involved in is a research project which was done in a group with two of the Master students from Philosophy faculty at the University of Pretoria. It was based on the out of sample forecasting ability of India’s Industrial production. Incorporation was Economics, Econometrics, Time-series Analysis and Data Mining. WORK EXPERIENCE:
