Research Methodology

Content

Objective

This course aims to teach the fundamental concepts, principles and applications related with scintific research and methods used.

Course Content

1) Introduction, research project and steps of a research project, basics of sampling.
2) Statistical inference (Estimation of a mean and proportion)
3) Statistical inference (Estimation of a mean and proportion), determination of the sample size.
4) Hypothesis testing, hypothesis, determination of the significance level, type I and II errors, rules of decision.
5) Parametric hypothesis testing (Test of a mean or a proportion of a population).
6) Non-parametric hypothesis testing (Contingency tables, Test Chi-2 of independance, homogeneity and conformity).
7) Non-parametric hypothesis testing. (Test of Kolmogorov-Smirnov, Wilcoxon signed rank test, Mann-Whitney U test)
8) Regression analysis, scatter plots. Regression and correlation analysis and hypothesis.
9) Simple linear regression, computing coefficients using least squares method. Pearson’s coefficient of correlation, tests of regression end correlation coefficients.
10) Multiple regression analysis. Part and partial correlation coefficients.
11) Non-parametric correlation. (Spearman’s rank correlation, coefficient of Kendall-Tau).

1. Carry out a scientific research project.
2. Define correctly the population, the sampling method and sample size for a research project.
3. Ascertain the appropriate method for data collection and data analysis.
4. Deduce the right and unbiased outcome as a result of a hypothesis testing.
5. Execute a parametric or non- parametric correlation analysis.
