+#### Hypothesen
+The following two hypotheses were applied in this project:
+
+- Using ECG data, a classifier can classify the four disease groupings with an accuracy of 80%.
+
+- Sinus bradycardia occurs significantly more frequently in the 60 to 70 age group than in other age groups.
+The procedure was as follows:
+
+1.
+2.
+3.
+4.
+
+### Demographic plotted
+
+#### Correlation matrix
+
+The following figure shows a correlation matrix of age groups and diagnoses. This matrix describes the four diagnosis groupings on the horizontal axis and the age groupings in decade increments on the vertical axis.
+
+The colour scale represents the correlation between the two types of categorization:
+
+- Blue (low)
+- Red (high)
+
+The exact procedure for creating the matrix can be found in the notebook [demographic_plots.ipynb](notebooks/demographic_plots.ipynb).

+
+
+
+#### Histogramm
+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.
+
+The exact procedure for creating the histogram can be found in the notebook [demographic_plots.ipynb](notebooks/demographic_plots.ipynb).
