user: I've been tracking the closing prices of a specific stock over the last 10 trading days for a report on market volatility. The figures I've recorded are 1000, 2000, 3000, 4000, 5000, 7000, 9000, 15000, 20000, and 30000. To get a better understanding of the price fluctuation and the risk associated with this stock, I need to calculate the standard deviation of these closing prices. Could you provide me with that statistic?
