Find the best distribution

Hi experts,

I have a data which represent the request comes into development center. I need to know the distribution of the arrival data into that center. I have calculate the inter-arrival time and calculate the frequency of the inter-arrival time. So, how can I know the fit probability distribution for this data?

* Please find a sample of the data file (an example)

7 data points are not enough to determine a model much more sophisticated than Poisson.
It's easy enough to find more complicated models that fit the data, but you'd probably just be fitting idiosyncrasies in the particular data set in a way that won't generalize to any other data.

Thanks for all,

Actually, it is a real data and more than 2000 record. I have calculate the inter arrival time and calculate the frequency to plot it and see which distribution can use. I have attached what I have got from plotting the frequency . The problem is I have problem to scale the data. SO, I plot it in minutes as shown in attached file.

Hi

Still stuck with this problem. I have no idea where is the problem. to simplify the problem,  I have the attached data as a time of arrival tasks to a center, I need to find the fit distribution to set the simulation. So, I calculate the inter-arrival time between coming tasks and try to plot the frequency in histogram to compare it with Poisson distribution.

The question is that: does my steps correct to find the fitness distribution for my arrival point?

How can I calculate the Poisson distribution for this data or how to find the best distribution?
