Random values extraction from an histogram

I have two distributions and I would like to casually correlate them. One distribution is represented by the park’s cars accesses for each quarter of the day (for example at the 8:00 two cars access in the park, at the 8:15 seven cars access in the park, at the 8:30 one car accesses in the park). The second distribution is represented by values couple where x represent the different battery SOCs and y is the number of cars which has the SOC x(i). The lengths of the two distributions are different and I would like to characterize each park’s access (not each park’s access for a quarter) whit a SOC.

Thank you

What's a SOC?

[Mahdi]

SOC stands for state of charge (how charged the battery is).

You can make the distributions have equal lengths by specifying the same number of bins for each histogram. Then use corrcoef.

What mystifies me is what information this would give, but then it’s not my analysis.

He did say it was to be a "casual" correlation, Star... :)

I wondered the same thing which is why I asked about the abbreviation to see if could make any sense of the query. Unfortunately, it doesn't help from that standpoint.

As Mark Twain said (and S Lord quoted here not long ago) --

"There is something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling investment of fact."

I have just solved with randsample function that takes in account the probability.

Thank you
