The class mean and standard deviation of the distribution used should be of most concern.
What is mean and standard deviation?
- In statistics, the measurement of variability known as the standard deviation (SD) is frequently utilised. It demonstrates how different things are from the norm (mean). While a high SD shows that the data are dispersed throughout a wide range of values, a low SD suggests that the data points tend to be close to the mean.
- The mean and SD provide information about the average value and the average distribution of values around the mean, respectively.
- The standard deviation is a measure that summarises how far away from the mean each observation is. The positive would exactly balance the negative if the discrepancies themselves were totaled together, making their aggregate equal to zero.
