This project was developed through the Data Science and Analytics course at the Mannheim University of Applied Sciences. A data science cycle was taught theoretically on the basis of lectures and implemented practically in the project.

### Demographic plots
#### Hypothesen #### Histogram
The following two hypotheses were applied in this project: The following histogram shows the age distribution. It illustrates the breakdown of the grouped diagnoses by age group as well as the absolute frequencies of the diagnoses.
- Using ECG data, a classifier can classify the four disease groupings with an accuracy of 80%. The exact procedure for creating the histogram can be found in the notebook [demographic_plots.ipynb](notebooks/demographic_plots.ipynb).
- Sinus bradycardia occurs significantly more frequently in the 60 to 70 age group than in other age groups.
