It includes code for obtaining descriptive statistics , frequency counts and crosstabulations including tests of independence , correlations pearson, spearman, kendall, polychoric , t-tests with equal and unequal variances , nonparametric tests of group differences Mann Whitney U, Wilcoxon Signed Rank, Kruskall Wallis Test, Friedman Test , multiple linear regression including diagnostics, cross-validation and variable selection , analysis of variance including ANCOVA and MANOVA , and statistics based on resampling.
Since modern data analyses almost always involve graphical assessments of relationships and assumptions, links to appropriate graphical methods are provided throughout. It is always important to check model assumptions before making statistical inferences. Although it is somewhat artificial to separate regression modeling and an ANOVA framework in this regard, many people learn these topics separately, so I've followed the same convention here.
Regression diagnostics cover outliers, influential observations, non-normality, non-constant error variance, multicolinearity, nonlinearity, and non-independence of errors. The identification of multivariate outliers is also considered. Power analysis provides methods of statistical power analysis and sample size estimation for a variety of designs. You can access your lectures, readings and assignments anytime and anywhere via the web or your mobile device.
In the later courses in the Specialization, we assume knowledge and skills equivalent to those which would have been gained in the prior courses for example: if you decide to take course four, Bayesian Statistics, without taking the prior three courses we assume you have knowledge of frequentist statistics and R equivalent to what is taught in the first three courses.
Coursera courses and certificates don't carry university credit, though some universities may choose to accept Specialization Certificates for credit.
