I’m new to statistics and need to create a probability distribution with the following study:

*Note: Due to proprietary reasons the example given below is the best representation of the real data.

Studies state that Geese Migrate in flocks within 2 Kilometers of each other.

100 cases were made each containing a different number of flocks observed. There were a total of 700 flocks observed between the 100 cases. Of the 700 flocks, only 100 of them had another flock within 2 Kilometers.

The data analysis and distribution are being completed in Matlab.

What is the best method to validate the data and provide a distribution on the observations? How would I go about visualizing / plotting the distribution?

I have the data together but unsure what distribution to use and how to visualize the data.
