Hello,
how do I increase the volatility (standard deviation) of a dataset (e.g., hourly price data)?
This is how this could look like.

Standard Deviation gives an estimate of the size of a typical deviation from the mean. Low Standard deviation means data points are closer to mean, Whereas High Standard deviation indicates higher deviation.
For increasing standard deviation, you can try below steps:
This would increase the deviation of all points from the mean and hence increase the Standard Deviation.
