Session variance is calculated by assessing the variability of data points within a specific session. The process begins by determining the mean of the data points in that session. Next, the differences between each individual data point and the session mean are computed and squared. These squared differences are then summed up, and to obtain the variance, this total is divided by the number of data points in the session, or by one less than that number if calculating the sample variance. This final value represents the session variance, indicating the degree of dispersion in the data points around the mean.

Indeed, you have accurately described the process of calculating session variance. By taking the squared differences of each data point from the mean, we effectively capture the spread or dispersion of the data within that session. This variance value provides valuable insights into the variability of outcomes during a specific session. It's a key statistical tool for understanding the distribution of results and assessing the consistency or volatility of a gambling session. The larger the variance, the more widely dispersed the data points are from the mean, indicating a greater degree of unpredictability in the outcomes. Conversely, a smaller variance suggests a more stable and predictable session. By utilizing variance calculations, players can gain a deeper understanding of the dynamics of their sessions and make informed decisions based on the insights provided.
