To determine the relationship between the COVID-19 Spread Speed and other indicators, we applied Pearson Product-Moment Correlation [13] to 286 data samples (the countries and regions in the combined dataset) and 116 data indicators (whose data indicators that have remained after the Sparse Data Indicator Filtering step). We then filtered out all non-significant correlation values (α = 0.05) and presented the obtained results in a form of a correlation semi-matrix (see Figure 3 ). On the Figure, white circles denote a positive correlation, while the black circles mean that the correlation is negative. The size of the circle is proportional to the correlation strength (the larger circle -the stronger the correlation) and the absence of a circle in a cell means that there was no correlation found or the correlation is not significant.
