## Congratulations![¶](https://knowledge.dataiku.com/latest/courses/statistics/course-complete.html#congratulations "Permalink to this headline")

You’ve just completed the **Interactive Visual Statistics** course. To recap, here are a few of the main takeaways from this course:

* Dataiku DSS provides the capabilities for performing descriptive and inferential statistics and also analyzing the effects of principal component analysis (PCA) on your data.

* Cards in a worksheet provide a straightforward way to explore your data set while organizing your workspace.

* Recognizing whether variables (or features) in your data set are categorical or numerical can help you to identify the appropriate statistics to compute on them in a univariate or bivariate analysis.

* The Fit Curves and Distributions cards in Dataiku DSS allow you to fit univariate and bivariate distributions to numerical columns in your data set, and to use curves for modeling the relationships between numerical columns.

* The Correlation Matrix card is useful for displaying pairwise correlation coefficient values for numerical columns in your data set.

* The Principal Component Analysis card allows you to visualize a 2-dimensional representation of the numerical columns in your data, using the first two principal component axes. The card also displays other features of the PCA implementation, to aid in analyzing the effects of dimensionality reduction on your data.

* You can implement hypothesis testing using the Statistical Tests cards. Dataiku DSS provides one-sample, two-sample, N-sample, and categorical tests. The tests are further grouped into location tests or distribution tests. Finally, each individual test card provides a description of the hypothesis that is being tested.
